Please add the code for SelectedIndexChanged for this.
Thanks in Advance

If you using GridView, then I doubt this is a .net core application?
And really, to help us out here - try posting at LEAST SOME of your gridviewe markup, as then we not trying to play a game of darts in a room with the lights out.
Assuming a GV like this:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="ID"
CssClass="table table=table-hover" Width="800px"
OnRowDataBound="GridView1_RowDataBound">
<Columns>
<asp:BoundField DataField="Firstname" HeaderText="First name" />
<asp:BoundField DataField="LastName" HeaderText="Last Name" />
<asp:TemplateField HeaderText="Select Hotel City">
<ItemTemplate>
<asp:DropDownList ID="cboCity" runat="server" Width="120px" Height="26px"
DataTextField="City"
DataValueField="City"
AutoPostBack="true"
OnSelectedIndexChanged="cboCity_SelectedIndexChanged">
</asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="HotelName" HeaderText="Hotel Name" />
<asp:BoundField DataField="Description" HeaderText="Description" />
</Columns>
</asp:GridView>
</div>
<div style="float:left;margin-left:20px">
<asp:Label ID="lbl1" runat="server" Height="179px" Width="450px" TextMode="MultiLine">
</asp:Label>
</div>
Code to load:
DataTable rstCity = new DataTable();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
LoadData();
}
void LoadData()
{
using (SqlConnection conn = new SqlConnection(Properties.Settings.Default.TEST4))
{
string strSQL =
"SELECT City FROM City ORDER BY City";
using (SqlCommand cmdSQL = new SqlCommand(strSQL, conn))
{
conn.Open();
rstCity.Load(cmdSQL.ExecuteReader());
cmdSQL.CommandText =
"SELECT * FROM tblHotelsA ORDER BY HotelName";
DataTable rstData = new DataTable();
rstData.Load(cmdSQL.ExecuteReader());
GridView1.DataSource = rstData;
GridView1.DataBind();
}
}
}
Ok, and now the code for the combo box (dropdown list). We assume auto-post back, so the code is thus this:
protected void cboCity_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList cboCity = (DropDownList)sender;
GridViewRow gRow = (GridViewRow)cboCity.NamingContainer;
int PK = (int)GridView1.DataKeys[gRow.RowIndex]["ID"];
string cr = System.Environment.NewLine;
string sResult =
$"Row index = {gRow.RowIndex} \n DataBase PK = {PK} <br/>" +
$" Hotel = {gRow.Cells[3].Text} <br/>" +
$"Combo Box selection = {cboCity.Text}";
lbl1.Text = sResult;
}
and thus we see/get this:
Edit2:
I should also note the following additonal information:
Of course I have to fill/load the drop down.. and that is done in row data bound event. Eg this:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DataRowView gData = (DataRowView)e.Row.DataItem;
DropDownList cboCity = (DropDownList)e.Row.FindControl("cboCity");
cboCity.DataSource = rstCity;
cboCity.DataBind();
cboCity.Items.Insert(0,new ListItem("Select", ""));
if (gData["City"] != DBNull.Value)
{
cboCity.Text = gData["City"].ToString();
}
}
}
Also, note how I don't care (or bother) with the GV selected index changed event. I really don't need it. I as noted, simple set autopost-back = true.
Last but not least?
you of course cannot build ANY working webforms page if you attemptto load up data in on-load but FORGET to check isPostback.
Since any button click, any post-back, or anything causing a post-back will of course trigger the page load event again, and BEFORE any of your other events. Thus, you need to ALWAYS ensure that you only load up the information one time on page load, since if you re-load the gv, or even a dropdown, then you tend to lose that choice by the user being made.
thus, that all imporant !IsPostBack stub is required for most pages.
Eg this:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
LoadData();
}
next up:
Since the dropdown list has the one grid row, then you are free to get data, hide data, enable or do whatever you please.
Just keep in mind that
For built in "databound" columns, you use the cells[] colleciton.
For any templated control, then you use gRow.FindControl("control name here")
So, since your "goal" in question is to operate on "txtrmrks" then that is a templated column, and thus we have to use findcontrol.
Say, like this:
air code warning!!!
protected void cboCity_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList cboCity = (DropDownList)sender;
GridViewRow gRow = (GridViewRow)cboCity.NamingContainer;
TextBox txtrmrks = (TextBox)gRow.FindControl("txtrmrks");
if (cboCity.Text == "Banff")
{
// disable the txtrmrks box
txtrmrks.Enabled = false;
}
}
You also not clear if you are going to working the value returned from the cbo box as "id", or "Title"
I suggest this way, and not to use ".Text" of the cbo, but this:
cboCity.SelectedItem.Value (gets value - ID)
cboCity.SelectedItem.Text (gets Text - Title)
if (cboCity.SelectedItem.Text)

Trying to add a second level nested table without sucess

I am trying to learn how to add an additional nested table inside the firstLevelGrid but I am not succeding. Any help would be appreciated.
Particularly I am doing something wrong in managing the OnRowDataBound when I create the second level grid, both in the markup and the code behind.
This is the code I have that generate the grid and the first level. I have not added my attempts for the second level grid just to avoid to mess up the code.
It is not homework, I am not a professional coder and I am a selflearner.
<div>
<asp:GridView ID="zeroLevelGrid" runat="server" AutoGenerateColumns="false" CssClass="Grid"
DataKeyNames="Code" OnRowDataBound="OnRowDataBoundZeroLevel">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<img alt="" style="cursor: pointer" src="images/plus.png" />
<asp:Panel ID="firstLevelPanel" runat="server" Style="display: none">
<asp:GridView ID="firstLevelGrid" runat="server" AutoGenerateColumns="false" CssClass="ChildGrid">
<Columns>
<!-- Here is where I add the second level grid copying the entire block "TemplateFiled" of the firstLevelGrid and renaming it secondLevel...-->
<asp:BoundField ItemStyle-Width="150px" DataField="Id" HeaderText="Id" />
<asp:BoundField ItemStyle-Width="150px" DataField="Code" HeaderText="Code" />
<asp:BoundField ItemStyle-Width="150px" DataField="Description" HeaderText="Description" />
<asp:BoundField ItemStyle-Width="150px" DataField="Quantity" HeaderText="Quantity" />
</Columns>
</asp:GridView>
</asp:Panel>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField ItemStyle-Width="150px" DataField="Id" HeaderText="Id" />
<asp:BoundField ItemStyle-Width="150px" DataField="Code" HeaderText="Code" />
<asp:BoundField ItemStyle-Width="150px" DataField="Description" HeaderText="Description" />
<asp:BoundField ItemStyle-Width="150px" DataField="Quantity" HeaderText="Quantity" />
</Columns>
</asp:GridView>
and my c# code:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
zeroLevelGrid.DataSource = GetData("select top 10 * from Table_xx");//top10 only for test purposes
zeroLevelGrid.DataBind();
}
}
private static DataTable GetData(string query)
{
string strConnString = ConfigurationManager.ConnectionStrings["Test1ConnectionString"].ConnectionString;
using (SqlConnection con = new SqlConnection(strConnString))
{
using (SqlCommand cmd = new SqlCommand())
{
cmd.CommandText = query;
using (SqlDataAdapter sda = new SqlDataAdapter())
{
cmd.Connection = con;
sda.SelectCommand = cmd;
using (DataSet ds = new DataSet())
{
DataTable dt = new DataTable();
sda.Fill(dt);
return dt;
}
}
}
}
}
protected void OnRowDataBoundZeroLevel(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string code = zeroLevelGrid.DataKeys[e.Row.RowIndex].Value.ToString();
GridView firstLevelGrid = e.Row.FindControl("firstLevelGrid") as GridView;
firstLevelGrid.DataSource = GetData(string.Format("IF (EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = N'{0}')) SELECT * from [{0}]", code));
firstLevelGrid.DataBind();
}
}
//here is where I add an OnRowDataBound event copying the above one as OnRowDataBoundFirstLevel
//but then I get lost...
}
I would be glad if someone could indicate me how to add an additional level of nested grid inside the firstLevelGrid identical to it. I would be happy to offer a bounty to get this right but unfortunatelly I do not have enough rep yet. Thank you a lot.

Similart to your firstLevelGrid, you have to declare the third level grid inside the firstLevelGrid as a template column
<asp:TemplateField>
<ItemTemplate>
<asp:GridView ID="secondLevelGrid" runat="server" AutoGenerateColumns="false" CssClass="ChildGrid">
<Columns>
<%--Your columns go here--%>
</Columns>
</asp:GridView>
</ItemTemplate>
</asp:TemplateField>
Then handle OnRowDataBound event for the firstLevelGrid
OnRowDataBound="firstLevelGrid_OnRowDataBound"
In the RowDataBound event you can get the grid view, data key and bind the child grid
protected void firstLevelGrid_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
GridView firstLevelGrid = e.Row.NamingContainer as GridView;
string code = firstLevelGrid.DataKeys[e.Row.RowIndex].Value.ToString();
GridView secondLevelGridView = e.Row.FindControl("secondLevelGrid") as GridView;
secondLevelGridView.DataSource = //GetData
secondLevelGridView.DataBind();
}
}

Delete data row from sql in a gridview

I am trying to delete data from a gridview using a a link button. I need help with the logic and making the link button remove the row data from the database on click.
GridView
<asp:GridView Style="width: 100%" ID="GvReportResults" runat="server" AutoGenerateColumns="False" EmptyDataText="No data" ShowHeaderWhenEmpty="True">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lnkBtnEdit" runat="server" CausesValidation="false" >Edit</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="LnkBtnRemove" runat="server" CausesValidation="false" CommandName="DeleteItem" CommandArgument='<%# Eval("OtherDataID") %>'>Delete</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="SourceID" HeaderText="ID" />
<asp:BoundField DataField="LastName" HeaderText="Last Name" />
<asp:BoundField DataField="FirstName" HeaderText="First Name" />
<asp:BoundField DataField="MiddleName" HeaderText="Middle Name" />
<asp:BoundField DataField="Title" HeaderText="Title" />
<asp:BoundField DataField="NationalID" HeaderText="SSN" />
<asp:BoundField DataField="DOB" HeaderText="DOB" />
<asp:BoundField DataField="HireDate" HeaderText="Hire Date" />
<asp:BoundField DataField="Address1" HeaderText="Address" />
<asp:BoundField DataField="City" HeaderText="City" />
<asp:BoundField DataField="State" HeaderText="State" />
<asp:BoundField DataField="PostalCode" HeaderText="Zip Code" />
</Columns>
</asp:GridView>
Store precedure thats importing data to gridview
private void BindGrid()
{
//set up arguments for the stored proc
int? FacilityID = (ddlFacility2.SelectedValue.Equals("-1")) ? (int?)null : int.Parse(ddlFacility2.SelectedValue);
int? OtherDataID = null;
//bind
GvReportResults.DataSource = this.DataLayer.model.MS_spGetOtherData(FacilityID, OtherDataID);
GvReportResults.DataBind();
}

Add OnClick attribute for the LinkButton, for example (added OnClick to your linkbutton code)
<asp:LinkButton ID="LnkBtnRemove" runat="server" CausesValidation="false" CommandName="DeleteItem" CommandArgument='<%# Eval("OtherDataID") %>' OnClick='LnkBtnRemove_Click'>Delete</asp:LinkButton>
Have OnClick listener as
protected void LnkBtnRemove_Click(object sender,EventArgs e)
{
string id = ((LinkButton)sender).CommandArgument;//CommandArgument is always returns string
Do_DeleteRow(id);//method to delete
BindGrid();
}
private void Do_DeleteRow(string id)
{
//your delete code will be added here
}

Just attach ItemCommand event to your grid
On web page in your grid definition add:
<asp:DataGrid OnItemCommand="Grid_ItemCommand" />
after that in code behind:
void Grid_ItemCommand(Object sender, DataGridCommandEventArgs e)
{
var id = Int32.Parse(e.CommandArgument.ToString()); //use parse if OtherDataID is int
//here goes logic for deleting row
this.DataLayer.model.spDeleteData(id);
//after deleting rebind grid
BindGrid();
}

Convert your boundfiled into Item Template, Here using sourceid will fire delete Query.
Code look like this:
protected void GvReportResults_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "DeleteItem")
{
int getrow = Convert.ToInt32(e.CommandArgument);
Label lblSourceID = (Label)GvReportResults.Rows[getrow].FindControl("lblSourceID");
bool flag=deleteRecord(lblSourceID.text);
if(flag)
{
succes msg!
}
else{ failed msg}
}
}
public bool deleteRecord(String SourceID)
{
try
{
SqlCommand cmd = new SqlCommand("Your Delete Query where condtion ", conn);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
return true;
}
catch(Exception ac)
{
return false;
}
}

Filtering a GridView with drop downs

I've been stuck on this for too long, and my Google-Fu is failing me. I'm new to C# and .Net, so I'm getting pretty frustrated here.
Here's what I have so far:
A method called GetData populates a DataSet, then I create a DataTable from that.
I bind the DataTable to the GridView, which is then made sortable. The table and sorting work fine, but I need to have drop down filtering on a few of the columns, but I can't get anything to work.
My ASP:
<asp:GridView id="gvEvaluator" Runat="server" Width="750" tooltip="Evaluator Status" AutoGenerateColumns="False"
EnableViewState="true"
HeaderStyle-ForeColor="#000000"
HeaderStyle-BackColor="#CCCCCC"
FooterStyle-ForeColor="#000000"
FooterStyle-BackColor="#CCCCCC"
Font-Size="8pt"
Font-Names="Verdana"
CellSpacing="0"
CellPadding="3"
ShowFooter="true"
AllowSorting="true"
GridLines="Both"
BorderColor="#ffffff"
BackColor="#ffffff"
ItemStyle-HorizontalAlign="Left"
visible="true"
AllowPaging="false"
AllowCustomPaging="false"
OnSorting="GridView_Sorting">
<Columns>
<asp:TemplateField HeaderText="<strong>Term</strong>"
HeaderStyle-HorizontalAlign="Center" HeaderStyle-VerticalAlign="Bottom"
ItemStyle-HorizontalAlign="Center" ItemStyle-VerticalAlign="top" >
<HeaderTemplate>
<asp:DropDownList ID="ddlTerm"
runat="server"
visible="true"
OnSelectedIndexChanged="ddlTermChanged"
AutoPostBack="true"
DataSourceID="gvEvaluator">
</asp:DropDownList>
</HeaderTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Dept" HeaderText="Dept" SortExpression="Dept></asp:BoundField>
<asp:BoundField DataField="Course" HeaderText="Course" SortExpression="Course"></asp:BoundField>
<asp:BoundField DataField="Section" HeaderText="Section"></asp:BoundField>
<asp:BoundField DataField="Evaluator" HeaderText="Evaluator" SortExpression="Evaluator"></asp:BoundField>
<asp:BoundField DataField="Type" HeaderText="Evaluator Type"></asp:BoundField>
<asp:BoundField DataField="Email_Address" Visible="false"></asp:BoundField>
<asp:BoundField DataField="Days_Since_Login" HeaderText="Days Since Login"></asp:BoundField>
<asp:BoundField DataField="Required_Work" HeaderText="Required Work" SortExpression="Required_Work"></asp:BoundField>
<asp:BoundField DataField="Total_Assigned" HeaderText="Total Assigned" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right"></asp:BoundField>
<asp:BoundField DataField="Total_Not_Started" HeaderText="Total Not Started" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right"></asp:BoundField>
<asp:BoundField DataField="Total_in_Progress" HeaderText="Total in Progress" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right"></asp:BoundField>
<asp:BoundField DataField="Total_Complete" HeaderText="Total Complete" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right"></asp:BoundField>
<asp:BoundField DataField="eval_id" Visible="false"></asp:BoundField>
<asp:TemplateField HeaderText="<strong>Need Reminder<strong>" ItemStyle-Width="250px">
<ItemTemplate>
<label for="hyplEvaluator" class="hide">Email Evaluator</label>
<asp:HyperLink ID="hyplEvaluator" runat="server" CssClass="BodyLink" Text='<%# DataBinder.Eval(Container, "DataItem.Need_Reminder")%>' NavigateUrl='' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
And my C#:
protected void getEvaluatorStatus()
{
try
{
ds = GetData();
DataTable myTable = ds.Tables[0];
if (myTable.Rows.Count != 0)
{
gvEvaluator.DataSource = ds;
gvEvaluator.DataBind();
gvEvaluator.Visible = true;
lblNoAssignment.Visible = false;
}
else
{
lblNoAssignment.Visible = true;
gvEvaluator.Visible = false;
}
//Adds attributes to hyplEmailContact
for (int i = 0; i < gvEvaluator.Rows.Count; i++)
{
string inSenderID = Convert.ToString(meth.decrypt(Session["UserID"].ToString(), Convert.ToString(Session["University"]), Convert.ToString(Session["Department"])));
string inRecptID = Convert.ToString(gvEvaluator.Rows[i].Cells[10].Text);
//custom string of attributes above
string customStr = "inSenderID=" + inSenderID + ",inRecptID=" + inRecptID;
//Adds the NavigateURL for Contact command to pass variables/attributes
HyperLink hyplEmailContact = (HyperLink)gvEvaluator.Rows[i].FindControl("hyplEvaluator");
hyplEmailContact.NavigateUrl = "javascript:openEmailGeneral(" + customStr + ")";
} //End for loop
}
catch (Exception ex)
{
Session["Error_Code"] = ex;
Response.Redirect("../Error.aspx");
}
I'm just a lowly bug squasher, so the only code I personally wrote was creating the GridView (from a DataGrid), the GetData method, making it sortable, and making the data exportable.

Something like this should work:
Handle the ddlTermChanged changed event:
Grab the new selected value in the dropdown list as so
protected void ddlTermChanged(Object sender, EventArgs e) {
var newValue = ddlTerm.SelectedValue;
//see step 3 below
}
Now filter the data and rebind it to the Gridview; something like:
protected void ddlTermChanged(Object sender, EventArgs e) {
var newValue = ddlTerm.SelectedValue;
DataTable t= GetDataByID(newValue);
gvEvaluator.DataSource=t;
gvEvaluator.DataBind();
}
On a separate note, all the transformations you are doing on the Gridview inside the getEvaluatorStatus method should have been handled in the OnRowDataBound event. By doing it the way you did it, every time you rebind the data (as in the case of filtering) you'll have to repeat the code inside the getEvaluatorStatus to do the transformations again. If you do it OnRowDataBound you won't have to repeat code as the event is raised for every row as it is being bound.

ASP.Net C# Gridview CheckBox Questiom

I am creating a web app using asp.net and c#. I am using gridview to display a list of staff from the database. I have added a checkbox so that the user can choose the staff they wish to pick. However when I go to check where the user clicked all the checkboxes show up unclicked.
This is my code:
<asp:GridView runat="server" id="gvPickStaff" GridLines="Horizontal" AutoGenerateColumns="false">
<Columns>
<asp:BoundField DataField="idusers" HeaderText="ID " ReadOnly="true" />
<asp:BoundField DataField="first_name" HeaderText="Name " ReadOnly="true" />
<asp:BoundField DataField="job_title" HeaderText="Job Title " ReadOnly="true" />
<asp:BoundField DataField="code_quality" HeaderText="Code Quality" ReadOnly="true" />
<asp:BoundField DataField="time_bonus" HeaderText="Time Bonus" ReadOnly="true" />
<asp:BoundField DataField="analysis_of_requirements" HeaderText="Analysis Of Requierements" ReadOnly="true" />
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="cbxSelect" runat="server" Checked="true" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
The Code Behind where I found the problem:
protected void btnAddStaff_OnClick(object sender, EventArgs e)
{
foreach(GridViewRow rowitem in gvPickStaff.Rows)
{
chk = (CheckBox)(rowitem.Cells[0].FindControl("cbxSelect"));
if(chk.Checked)
{
int staffid = Convert.ToInt32(gvPickStaff.DataKeys[rowitem.RowIndex]["idusers"]);
staffChosen.Add(staffid);
}
}
}
I fill the gridview like this:
protected void fillStaffChoiceList()
{
string strConnection = ConfigurationSettings.AppSettings["ConnectionString"];
MySqlConnection connection = new MySqlConnection(strConnection);
MySqlCommand command = connection.CreateCommand();
MySqlDataReader reader;
command.CommandText = "SELECT idusers, first_name, job_title, code_quality, time_bonus,analysis_of_requirements FROM `test`.`users` WHERE security_level > 1";
//SELECT idusers, first_name, last_name, job_title, code_quality, time_bonus,analysis_of_requirements FROM `test`.`users` WHERE security_level > 1;
connection.Open();
reader = command.ExecuteReader();
gvPickStaff.DataSource = reader;
gvPickStaff.DataBind();
connection.Close();
}
Can anyone perhaps see where I am going wrong?

I think problem is in page load
try this
public void Page_Load(object sender,EventArgs e)
{
if(!IsPostBack)
{
fillStaffChoiceList();
}
}

(rowitem.Cells[6].FindControl("cbxSelect")`
Your looking for the checkbox in the wrong cell I guess. Don't you get an exeption on the checkbox? It shouldn't be available in cell 0.

This is an example of what can be used.
((CheckBox)gvPickStaff.Rows[i].FindControl("cbxSelect")).Checked
I hope that this can help also this is making it explicitly into a Check-box thus being able to return as is supposed to.

Use this in the check box:
<input type="checkbox" name="chk1" id="chk1" value='<%# Eval("idusers") %>' />
And when you want ids which is selected, use:
request("chk1");
It will return all data which is checked with comma(,) separated
