Script control 'RadProgressManager1' is not a registered script control.

[RobDob]

Hi,

I am getting the following error within the event log sometimes..,  any ideas would be great.. 
The error seems to occur sometimes, the general process is that I upload a file,  I do NOT get a progress bar, and then the error occurs,  other times the file upload works correctly with a progress bar being displayed and then no error.

Thanks

Exception information:
    Exception type: ArgumentException
    Exception message: Script control 'RadProgressManager1' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

"That occurs if you are not calling the base implementation of that method - e.g. overriding OnLoad and not calling base.OnLoad. Please check your code for such problems."

So how do I do this,  where do I do this,  within what the RadProgressManager.  Is there an example? or could you post one please..

Thanks,

Hi,

The error is not particularly connected to our controls, but to asp.net controls live cycle itself and it depends on your scenario. I have searched the case in google and found many articles which discuss the issue. I suggest you take a look at some of them.

If this doesn't help please open a support ticket and send us your page.
