ASP.NET : Check for click event in page_load

Question

In c#, how can I check to see if a link button has been clicked in the page load method?

I need to know if it was clicked before the click event is fired.

Answer 1

Based on accepted answer and the answer of RealSteel this could be a more complete answer.

First add to the .aspx a button like this:

Then on the Page_Load method:

if(IsPostBack){
   var eventTarget = Request.Params["__EVENTTARGET"]
   // Then check for the id but keep in mind that the name could be 
   // something like ctl00$ContainerName$btnExport 
   // if the button was clicked or null so take precautions against null
   // ... so it could be something like this
   var buttonClicked = eventTarget.Substring(eventTarget.LastIndexOf("$") + 1).Equals("btnExport")

}
