I have a GridView with the following columns
<asp:TemplateField HeaderText="Name">
<FooterTemplate>
<asp:TextBox ID="txt_Name" runat="server"></asp:TextBox>
</FooterTemplate>
<ItemTemplate>
<asp:Label ID="lbl_name" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "t_Name") %>' />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txt_name" runat="server" Width="100px" Text='<%#DataBinder.Eval(Container.DataItem,"t_Name") %>'></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Created By">
<ItemTemplate>
<asp:Label ID="lbl_tabcreatedby" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "t_CreatedBy") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField HeaderText="Modify" ShowEditButton="True" />
<asp:CommandField HeaderText="Delete" ShowDeleteButton="True" />
<asp:TemplateField HeaderText="Add a New Name">
<FooterTemplate>
<asp:LinkButton ID="lnkbtn_AddName" runat="server" CommandName="Insert">Add Name</asp:LinkButton>
</FooterTemplate>
</asp:TemplateField>
And then in the Code Behind I am trying to access the txt_Name Textbox as
protected void gv_Name_RowCommand(object sender, GridViewCommandEventArgs e)
{
string t_Name = ((TextBox)(gv_Name.FooterRow.FindControl("txt_Name"))).Text;
// Insert Code
}
But I am getting null in the string t_Name everytime irrespective of what is the current Text of txt_Name.
However I can get the text if I disable the ViewState for the page. Any explanation.
I have got around this problem by using an additional variable, see the following:
Dim txtBox As TextBox = GridView1.FooterRow.FindControl("txtName")
Dim name As String = txtBox.Text
or you can try getting the textbox by column index, like following:
protected void gv_Name_RowCommand(object sender, GridViewCommandEventArgs e)
{
string t_Name = ((TextBox)(gv_Name.FooterRow.Cells[5].FindControl("txt_Name"))).Text;
// Insert Code
}
Try following code in gv_Name_RowCommand event
if (e.CommandName.Equals("Insert"))
{
string t_Name = ((TextBox)(gv_Name.FooterRow.FindControl("txt_Name"))).Text;
}
this should work
i think you data grid is being disconnected from the data source upon post back. If you are sure that data/ data value coming from db is not null.

How Do I Transfer Grid view values to next page. Grid view consist one of the text box(txtItemGroup) which values have to be entered by the user dynamically, not from the Data base.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" HorizontalAlign="Center">

</asp:TemplateField>
</Columns>
</asp:GridView>
In your GridView's RowCommand event put in the following code:
if (e.CommandName == "Send")
{
TextBox txt = (TextBox)GridView1.FindControls("txtItemGroup");
Session["ItemGroup"] = txt.Text;
}
In addition to this, put a Button or LinkButton in your GridView's ItemTemplate to send the value of the appropriate Textbox as you have put a TextBox and set it's CommandName property in the .aspx page as:
<asp:Button id="btnSend" runat="server" Text = ">" commandName="Send"/>
And then in the Page_Load event of the page where you want the value of TextBox to be viewed:
if (!IsPostback)
{
Label1.Text = Session["ItemGroup"].ToString();
//or
Label1.Text = (String)Session["ItemGroup"];
}
try this:-
Add a button just below that textbox like this:-
<asp:Button ID="btnsend" Text="Send" runat="server" CommandName="Send" />
In RowCommand event write like this:-
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Send")
{
GridViewRow row = (GridViewRow)((Control)e.CommandSource).NamingContainer;
TextBox TextBox1 = row.FindControl("txtItemGroup") as TextBox;
Response.Redirect("yourasppage.aspx?txt=" + TextBox1.Text);
}
}
On page load of `yourasppage.aspx' use this code
string txtval = Request.QueryString["txt"];
Hope this will help
I have a datagrid view, and I'd like to capture a datakeyname value on a selected row of a gridview. But in this scenario one of my columns (Event Title) will be a hyperlink, and when this link is clicked it will fire selectedindexchanged and capture DataKeyName which will be passed to populate a form. Here's my code. Currently my hyperlink field is not eve "clickable". Do I need to change my approach?
<asp:GridView ID="gvEventDetails" CssClass="gvEvent" runat="server" DataKeyNames="Event_ID"
AutoGenerateColumns="false" OnSelectedIndexChanged="gvEventDetails_SelectedIndexChanged" >
<Columns>
<asp:TemplateField HeaderText="Event Title">
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" Text='<%# Eval("Event_Title") %>' runat="server"></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Client Name">
<ItemTemplate>
<asp:Label ID="ClientName" runat="server" Text='<%# Eval("Name") %>'>
</asp:Label>
</ItemTemplate>
</asp:TemplateField>
The method:
protected void gvEventDetails_SelectedIndexChanged(object sender, EventArgs e)
{
string DataKey = gvEventDetails.SelectedValue.ToString();
}
Instead of a hyperlink, try a linkbutton with command name:
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton runat="server" CommandName="Select" CommandArgument='<%# Eval("Event_ID") %>' Text='<%# Eval("Event_Title") %>'
...
The rule is that posting back with common command names (Edit, Select, Delete, Cancel etc.) is correctly recognized by the event engine.
This is what I ended up doing
protected void gvEventDetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
string PK = (e.CommandArgument).ToString();
}
<asp:TemplateField HeaderText="Event Title">
<ItemTemplate>
<asp:LinkButton ID="HyperLink1" runat="server" Text='<%# Eval("Event_Title") %>'
CommandArgument='<%# Eval("Event_ID") %>'
></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
I'm having problems with a web app. I have a gridview connected with SQL datatable and in the footer I have textboxes (or dropdownlists) and an "insert" button. The problem occurs when I click on the button, and want to insert new line in my SQL table. It does not read text (we need to put in some strings) from textboxes. Of course insert does not happen, since some of the data must not be null.
I have the same problem with Editing rows.
this is my code:
Gridview:
<asp:GridView ID="gvUser" runat="server" AutoGenerateColumns="False"
DataKeyNames="ID" OnRowDataBound="gvUser_RowDataBound"
OnRowCommand="gvUser_RowCommand" ShowFooter="True">
<Columns>
<asp:TemplateField HeaderText="ID">
<ItemTemplate>
<asp:Label ID="lblID" runat="server" Text='<%# Bind("ID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:Label ID="lblName" runat="server" Text='<%# Bind("name") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtName" runat="server" Text='<%# Bind("name") %>'></asp:TextBox>
</EditItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtNewName" runat="server"></asp:TextBox>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Last name">
<ItemTemplate>
<asp:Label ID="lblLname" runat="server" Text='<%# Bind("lname") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtLname" runat="server" Text='<%# Bind("lname") %>'></asp:TextBox>
</EditItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtNewLname" runat="server"></asp:TextBox>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Edit" ShowHeader="False">
<FooterTemplate>
<asp:LinkButton ID="lnkAdd" runat="server" CausesValidation="False" CommandName="Insert"
Text="Shrani"></asp:LinkButton>
</FooterTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Code behind:
protected void BindGV()
{
//bind the SQL table to the GridView (no problem here)
}
protected void gvUser_RowDataBound(object sender, GridViewRowEventArgs e)
{
//here I bind the dropdownlist (did not include it in code snippet,
//since firstly I need to get text from textboxes
}
protected void gvUser_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("Insert"))
{
TextBox txtNewName = (TextBox)gvUser.FooterRow.FindControl("txtNewName");
TextBox txtNewLname = (TextBox)gvUser.FooterRow.FindControl("txtNewLname");
string NewName = txtNewName.Text; //this strings come up empty (just "")
string NewLname = txtNewLname.Text; //it should read from textboxes
AddRow(NewName, NewLname);
BindGV();
}
}
private void AddRow(string name, string lname)
{
//insert row into SQL datatable
}
EDIT:
Well it works now. Found a simmilar problem, and the author said he was able to get it work with adding EnableViewState="false" to the Gridview.
I tried and it worked. :)
Anyone here able to answer why would this work? And how will this correspond with other gv functions?
Try with this code - based on e.Item.FindControl
if (e.CommandName.Equals("Insert"))
{
TextBox txtNewName = (TextBox)e.Item.FindControl("txtNewName");
TextBox txtNewLame = (TextBox)e.Item.FindControl("txtNewLname");
....
}
When the user changes the text in the textbox's in the edit template and clicks update, when I try to grab those new values it still is graving the old value of the text box.

{
int key = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value);
Label CompanyID = (Label)GridView1.Rows[e.RowIndex].FindControl("txtCompanyID");
TextBox thisIssueDate = (TextBox)(GridView1.Rows[e.RowIndex].FindControl("txtIssueDate"));
TextBox NoticeIntentResponseDue = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtNoticeIntentResponseDue");
Response.Write(NoticeIntentResponseDue.Text + " " + thisIssueDate.Text);
Response.End();
TextBox DeadlineForQuestions = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtDeadlineForQuestions");
TextBox BidsDue = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtBidsDue");
TextBox ShortlistNotice = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtShortlistNotice");
TextBox FinalSelection = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtFinalSelection");
}
The response is showing me that the value being grabbed is still the origonal text value of the box. Not what you typed into the box.
In your grid view row updating event add the following condition
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
if (e.Row.RowState == DataControlRowState.Edit )
{
int key = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value);
Label CompanyID = (Label)GridView1.Rows[e.RowIndex].FindControl("txtCompanyID");
TextBox thisIssueDate = (TextBox)(GridView1.Rows[e.RowIndex].FindControl("txtIssueDate"));
TextBox NoticeIntentResponseDue = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtNoticeIntentResponseDue");
Response.Write(NoticeIntentResponseDue.Text + " " + thisIssueDate.Text);
Response.End();
TextBox DeadlineForQuestions = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtDeadlineForQuestions");
TextBox BidsDue = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtBidsDue");
TextBox ShortlistNotice = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtShortlistNotice");
TextBox FinalSelection = (TextBox)GridView1.Rows[e.RowIndex].FindControl("txtFinalSelection");
}
}
Update:
the problem looks like that you have also bind your Edit Item template columns with the data from data table, and when you are getting the data in the code behind you are not getting the updated data which the user updates in edit mode and u still getting the old data. If you remove the Binding from the Edit Item Template feilds then your code will work.
I figured it out, Derek was right. It had to do with the Binding Data on postback in page load. I binded the data every time instead of just the first time. Thanks
I have a GridView with an anonymous type. I need to check the value in a cell and highlight that cell if a condition is met. The problem is, I always get an empty string when I try to pull data out of the row's cells. I have successfully highlighted all the cells and I have checked in the Visual Studio 2010 debugger and confirmed that the Row has data (the row's DataItem has the values I need). This is happening on a PostBack, I'm not sure if that's a problem or not.
Here is the code and solutions I've tried:
protected void grvValidCourses_RowDataBound(Object sender, GridViewRowEventArgs e) {
if (e.Row.RowType == DataControlRowType.DataRow) {
String str = e.Row.Cells[6].Text.ToString(); // empty string
Label lbl = (Label) grvValidCourses.FindControl("lblEndDate"); // null
DataRowView rowView = (DataRowView)e.Row.DataItem; // exception about casting anonymous type
What's going on here? Why can't I get data from the cells?

UPDATE: I've been trying all your suggestions, but I get exceptions or nulls or empty strings. I've even re-created the problem in a simpler example and still can't figure it out! I'll keep trying though, and I appreciate any new suggestions.
Part 1 - Missing Text
You are probably getting blank values in the first part due to a need to access a child control:
String str = ((DataBoundLiteralControl)e.Row.Cells[6].Controls[0]).Text;
To see if your cells have any values in debug mode (check text in debug output window):
void grvValidCourses_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
System.Diagnostics.Trace.WriteLine(e.Row.Cells.Count);
foreach (TableCell c in e.Row.Cells)
{
System.Diagnostics.Trace.WriteLine(c.Text);
}
}
}
Part 2 - Missing Control
This is wrong:
Label lbl = (Label) grvValidCourses.FindControl("lblEndDate"); // null
You can't search the gridview for a row's control. You need to search the row.
Label lblProductOptionGrpName = (Label)e.Row.FindControl("lblProductOptionGrpName");
Part 3 - Accessing DataItem
DataBinder.Eval(e.Row.DataItem, "ColumnName")
Finally, I'm not sure what you're doing with your anonymous types, but you may need to check the contents before accessing properties:
if(MyControl.GetType() == typeof(HyperLink))
{
HyperLink TestLink = (HyperLink)MyControl;
TestLink .Visible = false;
}
Okay I finally figured out what is going on! I can only access the bound field through the row (e.g. e.Row.Cells[index].Text). So I used the bound field to get the ID of my item, then found the item in the database, got the date, compared it, and highlighted the row's cells. Not the most efficient way, but it works.
Code from simple sample:
Grid View Front End
<asp:GridView ID="gdv" runat="server" AutoGenerateColumns="True" OnSelectedIndexChanged="gdv_SelectedIndexChanged">
<Columns>
<asp:CommandField ShowSelectButton="True" SelectText="Select" />
<asp:BoundField DataField="id" HeaderText="#" ReadOnly="True" />
<asp:TemplateField HeaderText="CategoryName" >
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("name") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Description" >
<ItemTemplate>
<asp:Label ID="Label3" runat="server" Text='<%# Bind("desc") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:Label ID="lblSelected" runat="server" Text="No row selected"></asp:Label>
Code Behind Page
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack) {
var qry = ctx.Categories
.Select(c => new {
id = c.CategoryID,
name = c.CategoryName,
desc = c.Description,
});
gdv.DataSource = qry;
gdv.DataBind();
}
}
protected void gdv_SelectedIndexChanged(object sender, EventArgs e) {
selectRow();
}
private void selectRow() {
GridViewRow row = gdv.SelectedRow;
String strId = row.Cells[1].Text; // Bound Field column
lblSelected.Text = strId;
// use ID to get object from database...
}
If you can post markup, then it will be possible to figure out your issue.
You are doing this in wrong way,
this DataRowView rowView = (DataRowView)e.Row.DataItem;
should be DataRow rowView = ((DataRowView)e.Row.DataItem).Row;
protected void gridPanne_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType==DataControlRowType.DataRow)
{
Label label = (Label)e.Row.FindControl("Label4");
lbl.Text += " ** / ** "+label.Text;
}
}
