asp.net popup confirmation window

I need to add an "are you sure" popup window to a delete button and I am not sure how to get whether the user clicked Ok or Cancel.

Here is how I do it:

string message = "Are you sure you want to delete this user?";
            System.Text.StringBuilder sb = new System.Text.StringBuilder();
            sb.Append("return confirm('");
            sb.Append(message);
            sb.Append("');");
            Type type = this.GetType();
            ClientScript.RegisterOnSubmitStatement(type, "alert", sb.ToString());

I agree with above answers, but in case you don't wanna mix you server and client side code/events then I would suggest you go with AjaxToolKit confirm button http://bit.ly/NtmpOT

If you are using ajax control toolkit just use the confirmextender

if you want to know wich button the user clicked try this

add a hidden field in your webform

and use this to set his value when the user click Ok

  sb.Append("if (confirm(").Append(msg).Append("))")
                .Append("document.getElementById('")
                .Append(confirmResult.ClientID)
                .Append("').value = 'ok';");

in your code behind read the value of confirmResult to know if the user clicked ok or cancel

You could just set OnClientClick on the button to:

return confirm("Are you sure you want to delete this user?");

Then the submit/postback won't happen if the user doesn't click OK.

The simplest way is to just add this to your <input type="button|submit|reset" /> or <button /> html markup (no submit on cancel): OnClick="if(!confirm('Are you sure?')) return false;"

Rename the event to OnClientClick for <asp:Button /> - it is compatible with CausesValidation="True" and/or UseSubmitBehavior="False", because it gets added before them in the html markup.
