Question

I am having a page where i need to confirm whether to show updated grid or not

I am calling a javascript function using

ScriptManager.RegisterStartupScript(this, typeof(string), "Error", "confirm('Are u sure');", true);

What I want to know is how to get the return value of confirm in C# code behind.

Answer 1

Instead of this

ScriptManager.RegisterStartupScript(this, typeof(string), "Error", "confirm('Are u sure');", true);

use this

ScriptManager.RegisterStartupScript(this, typeof(string), "Error", "ConfirmUser('Are u sure');", true);

<script type='javascript'>
 function ConfirmUser(msg)
 {
  if(confirm(msg))
    __doPostBack('','');
 }
<script>

see following links to know more about __doPostBack
