assign value to label inside the gridview using c#

Dear Friend,

Try this:-

1). First add a tag inside the gridview

<footertemplate>
  <asp:label id="lblText" runat="server" xmlns:asp="#unknown"></asp:label>
</footertemplate>

2). Then in the gridrowdatabound event:-

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType == DataControlRowType.Footer)
  {
      Label lblText=(Label)e.row.Findcontrol("lblText");
      lblText=[Your Value];
  }
}       

I hope this helps you out. Don't forget to mark this as your answer if it solves your purpose.

Thanks
