Using button code on a datagrid

I need to put buttons in a datagrid. I know how to do this with the
<templatecolumn> , but my question is how do I access it in the
codebehind .vb file, if the number of buttons is variable? I need to put some
code in the _Click event of each button.

Hi,

Try this code. Here is the code for how to put Radio Button in Datagrid, and how to select the perticular row which is clicked is given..

<asp:TemplateColumn>
<ItemTemplate>
<asp:RadioButton AutoPostBack="True" id="rbSel" OnCheckedChanged="SelectOpt" runat="server"></asp:RadioButton>
</ItemTemplate>
</asp:TemplateColumn>

-------------------------------------------------------------------------

public void SelectOpt(object sender,EventArgs e)
{

System.Web.UI.WebControls.RadioButton rb = new System.Web.UI.WebControls.RadioButton();
rb = (System.Web.UI.WebControls.RadioButton) sender;
sRbText = rb.ClientID;

foreach (DataGridItem i in Dg.Items )
{
rb = (System.Web.UI.WebControls.RadioButton) i.FindControl ("rbSel");
rb.Checked = false;
if (sRbText==rb.ClientID)
{
rb.Checked = true;
//txtSiraNo.Text = rb.Text.Trim();
// if you want to get a property of the selected id
Dg.SelectedIndex =i.ItemIndex;

}
}
}
