I have 2 button controls. When I click one i'm trying to determine which one caused a postback in the page load. How to do determine this?
What about using CommandName and CommandArgument has shown in this example. This way you can have just one handler.
<asp:Button id="Button1"
Text="Sort Ascending"
CommandName="Sort"
CommandArgument="Ascending"
OnCommand="CommandBtn_Click"
runat="server"/>
<asp:Button id="Button2"
Text="Sort Descending"
CommandName="Sort"
CommandArgument="Descending"
OnCommand="CommandBtn_Click"
runat="server"/>
