GridView - Get Column Header + Button Link- RowCommand

Question

Hi all...

 

I need help in GridView Binding -

 

My GridView Design in aspx page is -

 

<asp:GridView ID="grd_Data" runat="server" AutoGenerateColumns="false">

<Columns>

<asp:ButtonField DataField="N" HeaderText="EName" />  

<asp:ButtonField DataField="C" HeaderText="ECode" />
<asp:ButtonField DataField="D" HeaderText="EDept" />

 <asp:ButtonField DataField="S" HeaderText="ESal" />

</Columns>

</asp:GridView>

--------

Now - THe columns - ECode ; EDept and ESal - are all numeric.

 

I want a logic that -

When I click on any number of any column (ECode ; EDept; ESal) ; I want its corresponding Headertext and  Datafield in CS Page - In RowCommand Event.

 

i.e. - Get corresponding column header text of selected value.

 

Also, WHere ever the number is 0(zero); the user should not be able to click the number.

 

How to achieve this ??
