radalert from codebehing not firing first time

[Michael]

I am having trouble getting radalert to fire the first time when following the example posted here:

http://www.telerik.com/support/kb/aspnet-ajax/window/calling-radalert-from-codebehind-all-versions-of-radwindow.aspx

I am using the last example:
3. Calling radalert on RadAjax callback: You can use the ResponseScripts collection of RadAjaxManager for this purpose:

Here's my button codebehind:

 

protected void uxOkButton_Click(object sender, EventArgs e)

 

{

uxAjaxManager.ResponseScripts.Add(

"(function(){var f = function(){radalert('Please select criteria.',300,100,'Search');Sys.Application.remove_load(f);};Sys.Application.add_load(f);})()");

 

}

The radalert only pops up the second time I click on the OK button...

I know in the KB article the last post suggests using the RegisterStartupScript method of the ScriptManager to resolve the issue of the radalert not firing the first time, but I can not do this as I have a RadScriptManager on my page and you can not have both a RadScriptManager and a ScriptManager on the same page (http://telerikwatch.com/2008/05/optimization-tips-using.html).

Hi Michael,

In your case when you use the RadAjaxManager control the Sys.Application.load event is fired, and then the script from the codebehind is loaded by RadAjaxManager. That is why the script is executed the second time when you click on the button.

In such scenario you do not need to use the Sys.Application.load event and your code should look like this :

uxAjaxManager.ResponseScripts.Add("radalert('Please select criteria.',300,100,'Search');");

We will change the mentioned KB article in order to cover all of the possible scenarios.
