I have a RadAsyncUpload inside a RadGrid, all of which is inside a RadWizard. These controls are in a user control that is loaded dynamically by the content page in a placeholder.
Whenever I go into Add or Edit mode in my RadGrid, the RadAsyncUpload does not render and I get the following error in my JS console
(see attachment error1.png)
Is there a known issue with using RadAsyncUploads in RadGrids, or a specific way to go about it?
I've tried mimicking this demo but I get the same error. https://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandradasyncupload/defaultvb.aspx?product=asyncupload
Any help is greatly appreciated!
