Hi,

Set the CommandArgument Property of the button or linkbutton as your column header text. Like:

ASP.NET

<asp:linkbutton id="lnkAddNew" runat="server" text="Add" commandname="AddNew" commandargument="MyColumnHeaderText" xmlns:asp="#unknown" />

And Handle it like:

C#

if (e.CommandName == "AddNew")
{
    lbl1.Text=e.CommandArgument.ToString();
    // Returns MyColumnHeaderText
}

Or

C#

if (e.CommandName == "AddNew")
{
    CommandField cf=sender as CommandField;
    lbl1.Text=cf.HeaderText;
    // Returns MyColumnHeaderText
}

Hi Mr.Amit

no i am giving example. i am using vb

<asp:HyperLinkField HeaderText="Plan1" Text="Plan1" NavigateUrl="~/PlanPopup1.aspx" Visible="False" />

<asp:CommandField ShowSelectButton="True" HeaderText="Plan1" SelectText="Plan1" ControlStyle-Width="80px" ItemStyle-HorizontalAlign ="Center" HeaderStyle-HorizontalAlign="Center"/>

<asp:HyperLinkField HeaderText="Plan2" Text="Plan2" NavigateUrl="~/PlanPopup1.aspx" Visible="False" />

<asp:CommandField ShowSelectButton="True" HeaderText="Plan2" SelectText="Plan2" ControlStyle-Width="80px" ItemStyle-HorizontalAlign ="Center" HeaderStyle-HorizontalAlign="Center"/>

In this i have two commandFields. i.e is plan1 and plan2
once i click on plan1 column i should get the plan1 header text.

Use This:

CommandField cf=(CommandField)e.CommandSource;
lbl1.Text = cf.HeaderText;

hi Amy ok i changed the code to Dim cf As CommandField = DirectCast(e.CommandSource, CommandField) txtNOB.Text = cf.HeaderText but error is showing at e.CommandSource err.msg is: CommandSource is not a member of system.Web.UI.WebControls.GridViewSelectEventArgs

Member 8715996 27-Jul-12 6:21am

u want to try

CommandField cf=(CommandField)e.CommandSource;
lbl1.Text = cf.HeaderText;
code??
if yes
i am getting the "CommandField is a type and cannot be use as an expression"

and one more thing after "e." there is no CommandSource only NewSelected Index is there
