Delete Individual row of gridview without deleting from database

Delete Individual row of gridview without deleting from database - c#

I am using Linq-to-SQL in ASP.NET & C#. I want to delete individual row of gridview by click on delete button (i.e. CommandField or TemplateField) with gridTrainingNeed_RowDeleting event.
Here is my code for loading gridview on page load.
int departmentId;
int branchId;
int positionId;
double month;
int levelId;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Initialize();
}
}
public void Initialize()
{
ddlBranch.DataSource = TrainingManager.GetBranchName();
ddlBranch.DataBind();
ddlDepartment.DataSource = DepartmentManager.GetAllDepartments();
ddlDepartment.DataBind();
ddlPosition.DataSource = TrainingManager.GetDesignationName();
ddlPosition.DataBind();
ddlLevel.DataSource = TrainingManager.GetLevelName();
ddlLevel.DataBind();
gridTrainingNeed.DataSource = TrainingManager.GetAllEmployees(departmentId, branchId, positionId, month, levelId).ToList();
gridTrainingNeed.DataBind();
}
Now I am going to keep my design code:
<div class="innerLR">
<div class="seperator bottom" />
<div class="widget">
<div class="widget-head">
<h4 class="heading">
Send Circulation To
</h4>
</div>
<div class="widget-body">
<table class="tableShow" cellpadding="3" cellspacing="0">
<tr>
<td>
<asp:DropDownList ID="ddlBranch" runat="server" DataTextField="Name"
DataValueField="BranchId" Width="170px" AppendDataBoundItems="True"
>
<asp:ListItem Text="---Select Branch---"/>
</asp:DropDownList>
</td>
<td>
<asp:DropDownList ID="ddlDepartment" runat="server" AppendDataBoundItems="True"

</td>
</tr>
</table>
</div>
</div>
<div>
<asp:GridView ID="gridTrainingNeed" runat="server" AutoGenerateColumns="False"
EnableModelValidation="True" CellPadding="4" ForeColor="#333333"

<asp:CommandField HeaderText="Delete" ShowCancelButton="False"
ShowDeleteButton="True" />
</Columns>
<EditRowStyle BackColor="#999999" />
<FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />

<SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
</asp:GridView>
</div>
</div>
Thus, I want to delete row one by one with RowDeleting Event from displaying data on gridview not from database.
protected void gridTrainingNeed_RowDeleting(object sender, GridViewDeleteEventArgs e)
{//Row delete code
}
Thank You.

Instead of assigning the DataSource directly like you are doing:
gridTrainingNeed.DataSource = TrainingManager.GetAllEmployees(departmentId, branchId, positionId, month, levelId).ToList();
Store the result in Page level List. Define a page level List like:
//Define List at page/class level
List<Employee> gridList = new List<Employee>();
Then in your method Initialize
gridList = TrainingManager.GetAllEmployees(departmentId, branchId, positionId, month, levelId).ToList();
gridTrainingNeed.DataSource = gridList;
gridTrainingNeed.DataBind();
You need to persist the List<Employee> in memory on PostBack, Use Session/ViewState etc. (See ASP.Net State Management).
Later in your gridTrainingNeed_RowDeleting, get the ID from row or any field that uniquely identify an employee. Query your list and remove that object from the List in memory. Re-assign the DataSource to the modified list and call DataBind.

how to get values from gridview in asp.net web forms?

hello all i am new to asp.net and i want to get values from grid view when i click on Edit or Delete or and i don't know how to do it i am sending data table to show table data and i don't want to use SQL Data Source from Visual tool box.
i have tried the following code but it gives error
protected void dgv1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Edit")
{
int rowindex = ((GridViewRow)((LinkButton)e.CommandSource).NamingContainer).RowIndex;
dgv1.EditIndex = rowindex;
dgv1.DataBind();
}
}
}
my view page code is as follows
<form id="form1" class="form-control form-group" runat="server">
<asp:Panel ID="pnlAddCustomers" runat="server" Height="376px">

</form>
and body pic is as follow
enter image description here

Try this:
LinkButton lnkBtn = (LinkButton)e.CommandSource; // the button
GridViewRow gvRow = (GridViewRow)lnkBtn.Parent.Parent; // the row
You may also get the data key index by adding DataKeyNames="MyTableKeyID" to the <asp:GridView /> tab, then
string selectedKeyIndex = this.GridView1.DataKeys[myRow.RowIndex]["MyTableKeyID"].ToString();

Not able to display selected value in drop down list in asp.net

Please help

Try to get the DropDownList value using foreach loop
foreach(RepeaterItem item in rpt1.Items)
{
DropDownList ddl = (DropDownList)item.FindControl("ddl");
string ddl_value = ddl.SelectedValue;
}
Note: rpt1 is Repeater's Id
also note that by using foreach loop you'll get all dropdownlist's
value, so you have to use it according your scenario.

When a Control is inside a Repeater, you cannot access it directly. You will have to use FindControl with an Index number of the Item that contains the Control inside the Repeater.
DropDownList drp = Repeater1.Items[index].FindControl("ddlqty") as DropDownList;
drp.SelectedValue = "2";
UPDATE
If you want to set the DropDownList values from the cart, and update the cart when you change the items you can do this by adding OnItemDataBound and OnSelectedIndexChanged
<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
<ItemTemplate>
<asp:DropDownList ID="ddlqty" runat="server" OnSelectedIndexChanged="ddlqty_SelectedIndexChanged" AutoPostBack="true">
<asp:ListItem Value="1">1</asp:ListItem>
<asp:ListItem Value="2">2</asp:ListItem>
<asp:ListItem Value="3">3</asp:ListItem>
</asp:DropDownList>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("tocht_id") %>' Visible="false"></asp:Label>
</ItemTemplate>
</asp:Repeater>
Code behind
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
int itemsInCart = 3;
//find the dropdownlist using findcontrol
DropDownList drp = e.Item.FindControl("ddlqty") as DropDownList;
//set the correct cart value
drp.SelectedValue = itemsInCart.ToString();
}
protected void ddlqty_SelectedIndexChanged(object sender, EventArgs e)
{
//cast the sender back to a dropdownlist
DropDownList drp = sender as DropDownList;
//get the item as a repeater item
RepeaterItem item = drp.NamingContainer as RepeaterItem;
//find the label with the product ID in the Repeater
Label lbl = Repeater1.Items[item.ItemIndex].FindControl("Label1") as Label;
//get the product id from the attri
int productID = Convert.ToInt32(lbl.Text);
//convert the selectedvalue back to an int
int itemsInCart = Convert.ToInt32(drp.SelectedValue);
//you now have the product id and the new cart amount
}

Below is the code that will use to Bind Repeater at page load under IsPostback condition on page load event
private void BindData()
{
DataTable dt = new DataTable();
dt.Columns.Add("ID", Type.GetType("System.String"));
dt.Columns.Add("ItemName", Type.GetType("System.String"));
dt.Columns.Add("Category", Type.GetType("System.String"));
dt.Columns.Add("Rate", Type.GetType("System.String"));
dt.Columns.Add("Qty", Type.GetType("System.String"));
dt.Columns.Add("Total", Type.GetType("System.String"));
for (int i = 1; i <= 10; i++)
{
DataRow dr = dt.NewRow();
dr["ID"] = 1;
dr["ItemName"] = "hoodie";
dr["Category"] = "Hoodie";
dr["Rate"] = 25;
dr["Qty"] = 4;
dr["Total"] = (4 * 25);
dt.Rows.Add(dr);
}
Repeater1.DataSource = dt;
Repeater1.DataBind();
}
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
DropDownList ddlQty = new DropDownList();
ddlQty = (DropDownList)e.Item.FindControl("ddlqty");
HiddenField hdn = new HiddenField();
hdn = (HiddenField)e.Item.FindControl("hdnQty");
if (hdn.Value != "")
{
ddlQty.SelectedItem.Selected = false;
ddlQty.Items.FindByValue(hdn.Value).Selected = true;
}
}
}
You need to use ItemDataBound event of Repeater that will give you control at the time of binding data to repeater and you can change value of that control while binding records.
Another thing that you have to do is to handle dropdown selected index event that will give you value of qty and you can use it to rebind repeater.

I am able to solve my issue, now i can see selected value in the text of dropdownlist. However i have to remove Repeater. And used gridview instead. I am having 1 issue that when I click on Save using <asp:LinkButton ID="lnkUpdate" runat="server" CommandName="Update" Text="Save" ></asp:LinkButton> it refreshes the page and value again goes to 1 which is by default value.

Please help

Writing an all new answer since the first one was way too verbose.
Set the ShowFooter="true" on your GridView. Next edit the first TemplateField like this:
<asp:TemplateField HeaderText="Select" ItemStyle-Width="5">
<ItemTemplate>
<asp:CheckBox ID="chkDelete" runat="server" onClick="Check_Click(this)" />
</ItemTemplate>
<FooterTemplate>
Number of records: <%# grdTeacherProfile.Rows.Count %>
</FooterTemplate>
</asp:TemplateField>
And that's all you should need. At least works while I tested.
There should also be some way to span the text to several columns, but didn't have time to test for that..

int RowCount = grdTeacherProfile.Rows.Count;
lblDisplayCount.Text = RowCount.ToString();
Try this code.

If I use frm.Controls.Add(tblOne) instead of frm.Controls.Add(divContent) then it works fine because tblone doesn't have an Ajax Control. But divContent has both the table as well as Ajax Controls, and it throws the above exception. I have tried many options like overriding OnInit and OnPreRender but doesn't work for me.

It could be due to the placement of ToolkitScriptManager in your code. See if this resolves your problem:
Error: Extender controls may not be registered before PreRender

Finally i have resolved this problem by using JavaScript code & it works better for me, i would like to thanks for all who gives their valuable time & feedback.
The code is here :
<script>
function Panel1() {
var panel = document.getElementById("<%=printablediv.ClientID %>");
var printWindow = window.open('', '', 'height=400,width=800');
printWindow.document.write('<html><head><title>newTable</title>');
printWindow.document.write('</head><body >');
printWindow.document.write(panel.innerHTML);
printWindow.document.write('</body></html>');
printWindow.document.close();
setTimeout(function() {
printWindow.print();
printWindow.close();
}, 1000);
return false;
}
</script>

The gridview Gender column shows true/false instead of male/female.
Thanks!

You need a TemplateField for this. Assuming Male equates to True, this should work:
<asp:TemplateField HeaderText="Gender" SortExpression="Gender">
<ItemTemplate><%# (Boolean.Parse(Eval("Gender").ToString())) ? "Male" : "Female" %></ItemTemplate>
</asp:TemplateField>
