Cannot read properties of undefined (reading 'open') at window.radopen

[Nigel]

The pop up that I am trying to display when clicking on an <a> tag seems to not be able to take in the URL that I have passed into it via a post-back. All this does is to throw me an error stating. These snippet of  code seems to be working on a previous iteration of an application but seems to be continuing to throw this error in this new iteration of the application that I am currently developing.

Uncaught TypeError: Cannot read properties of undefined (reading 'open')

Hi Nigel,

I tried to reproduce the problem with the following page but without success:

        <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
            <script type="text/javascript">
                function OpenForm(arg) {
                    console.log("Argument: ", arg);
                    var encodedArg = encodeURIComponent(arg);
                    window.radopen(encodedArg, "ConfirmDialogue");
                }


                function clientBeforeShow() {

                }

            </script>
        </telerik:RadCodeBlock>
    </form>

Based on the error message and the code snippet you've provided, it seems like the issue might be related to the window.radopen method not being recognized. This typically happens when there is a javascript error on the page, or when radopen is not defined or accessible in the window scope. Here are a few steps to troubleshoot and potentially resolve the issue:

1. Ensure Telerik Scripts are Loaded: Make sure that the Telerik scripts are correctly loaded on your page. Check the DevTools Network tab for blocked or not loaded script resources.

2. Correct Use of RadWindowManager's Client-Side API: To open a RadWindow programmatically from the client-side, you should ensure that you're using the RadWindowManager's client-side API correctly. Here's a revised version of your OpenForm function that explicitly uses the RadWindowManager's client-side API:
   
   

   function OpenForm(arg) {
       console.log("Argument: ", arg);
       var encodedArg = encodeURIComponent(arg);
       var windowManager = $find("<%= RadWindowManager1.ClientID %>");
       if(windowManager) {
           windowManager.open(encodedArg, "ConfirmDialogue");
       } else {
           console.error("RadWindowManager not found");
       }
   }
   

   This code snippet explicitly retrieves the RadWindowManager instance using its ClientID and then calls the open method on it, passing in the URL and the ID of the specific RadWindow you wish to open. 

3. Verify the URL: Ensure that the URL you're trying to open is accessible and correct.

4. Look for JavaScript errors: If after following these steps the issue persists, it might be helpful to look into any JavaScript errors that might be occurring on the page or conflicts with other scripts. Additionally, ensuring that your Telerik UI for ASP.NET AJAX controls are up to date could also help resolve compatibility issues.

Please try these suggestions and let me know if the issue persists. If you have further information or if the problem continues, providing additional details or steps to reproduce the issue could help in diagnosing and addressing it more effectively. Please also, create a minimal version of your page that only includes the necessary elements to reproduce the issue. This can help isolate the problem by removing any potential interference from other scripts or page elements. Also provide the page here so that we can test and examine it.
