Processing AJAX request in ASP.NET

Question

I'm working with an AJAX button and label controls. When the user clicks the button, the data is updated in the label.

But after clicking the button, the Page_Load event occurs, and I don't want it, because all data is being initialized to default values.

How can I check in Page_Load event that it's an AJAX request?

I'm using UpdatePanel and ScriptManager as AJAX tools.

Answer 1

in the page load check

  if (!Page.IsAsync)
  { 
  }
