You can try this :- 

.aspx 

                   <asp:Button 
ID="lnk" runat="server" commandname="DataCommand" commandargument="<%# Eval("ID" )%>" text="Detail Information"/>


.aspx.cs 

Protected Void Grid1_RowCommand(object sender, GridViewEventArgs e) {  if(e.CommandName=="DataCommand")      {       // Get the value of command argument         var value= e.CommandArgument;       // Do whatever operation you want.       } }
