Hello,
There are two update panel containing two text boxes. I have two buttons thats are triggered with these update pannels asynchronously.

On Cick even of the button I am writing code like as

C#

protected void Button1_Click(object sender, EventArgs e)
   {
       //Server.Transfer("http://www.google.co.in/");
       //Response.Redirect("http://www.google.co.in/");

       TextBox1.Text = "Ajax Clicked";
       Thread.CurrentThread.ThreadState..Sleep(100000);
   }

C#

protected void Button2_Click(object sender, EventArgs e)
   {
       TextBox2.Text = "Ajax Asynchrnously clicked";
   }

In this scenario, The AJAX not showin the asynchrnous behaviour. Neither first first Text box is updating nor second if we click on button one first.

Thank you to let me know the reason behind this situation.

Regards
Rajeev

can you post code of your aspx page?

rajeev,

Is the thread.sleep part of the functionality or are you just trying to experiment?

Erm...surely the HTTP AJAX request would time out before your Thread.Sleep ends resulting in no response to your AJAX request and so the textbox wouldn't be updated. The default (I think) is a 30 to 60 second timeout, you will have to increase this to 100 (if not more) for your code to work. If that doesn't fix it in itself, it is almost certainly going to be a problem.

Hope this helps,
Ed
