To get the GridViewRow of a selected item Template, set an OnClick to a method to handle the event.

i.e.

 

In the method you can reference the clicked link button by using the following code:

[codesyntax lang=”csharp”]

GridViewRow row = (GridViewRow)((Control)sender).NamingContainer;
string item = row.Cells[1].text;

[/codesyntax]

Dim StringWriter1 As IO.StringWriter
Dim StringBuilder1 As StringBuilder = New StringBuilder
StringWriter1 = New IO.StringWriter(StringBuilder1)
Dim TextWriter1 As HtmlTextWriter = New HtmlTextWriter(oStringWriter)
label.RenderControl(oTextWriter)
Response.Clear()
Response.ClearHeaders()
Response.ContentType = “application/vnd.xls”
Response.AddHeader(“Content-Disposition”, “attachment;filename=WLMS-exlfile.xls”)
Response.Write(StringWriter1.ToString())
Response.Flush()
Response.End()

Here is a trick one, because IntelliSense doesn’t bring up the “SelectedValue” property for a RadioButtonList, or a DropDownList in an EditItemTemplate for GridViews you may forget that “SelectedValue” is an actual property of these controls.

Here is how you can set the selected value of a RadioButtonList inside an EditItemTemplate

[codesyntax lang=”html4strict”]

<asp:TemplateField HeaderText="Payment">
<ItemTemplate>
    <asp:Label ID="lablePayment" runat="server" Text='<%#Eval("PayName")%>' />
</ItemTemplate>
<EditItemTemplate>
  <asp:RadioButtonList Runat = "server" ID="rblPaymentType" SelectedValue='<%#Eval("PayTypeID")%>'>
    <asp:ListItem Text="Check" Value="1"></asp:ListItem>
    <asp:ListItem Text="Credit Card" Value="2"></asp:ListItem>
  </asp:RadioButtonList>
</EditItemTemplate>
</asp:TemplateField>
