How to check whether UpdatePanel is posting back?

Question

Is there a way to determine if an has performed an Ajax postback similar to how we can use...

if(!Page.IsPostBack) { .         


        

Answer 1

Try out following:

var controlName = Page.Request.Params.Get("__EVENTTARGET");
if (!String.IsNullOrEmpty(controlName))
{
     // Use FindControl(controlName) to see whether 
     // control is of UpdatePanel type
}
