radconfirm callback funtion not found

[Andy]

I have been struggling to get the callback function to be recognized.  My situation is that I have a javascript function that executes when a user clicks a button.  This function contains code similar to the following to open the radconfirm prompt window

 var oManager = GetRadWindowManager();
    oManager.radconfirm(pMsg, "returnFunction",400,300,"Popup Title");

 

When the user clickes either the Ok or Cancel button the following error occurs.

JavaScript runtime error: Function expected

 

The function returnFunction(arg) exsits in the same javascript file but is not recognized.

Any ideas as to the issue.

Hello Andy,

When called from JavaScript, the radconfirm() method takes a function object for the callback function. It takes a string when called from the code-behind. Reference to the full functionality of the widget: https://docs.telerik.com/devtools/aspnet-ajax/controls/window/alert,-confirm,-prompt-dialogs/radconfirm-dialog.

Here's an example:

<script type="text/javascript">
    function confirmCallBackFn(arg) {
        radalert("Confirm returned the following result: " + arg);
    }
    function callRadConfirm() {
        radconfirm('Are you sure?', confirmCallBackFn); //no quotes around the callback function object reference
    }
</script>
<asp:Button Text="call RadConfirm" ID="Button1" OnClientClick="callRadConfirm(); return false;" runat="server" />
<telerik:RadWindowManager runat="server" ID="rwm1" RenderMode="Lightweight"></telerik:RadWindowManager>
