Microsoft JScript runtime error
posted

I am using a WebHierarchicalDataGrid with a WebHierarchicalDataSource with three levels.  We use it on a web application, with Infragistics2.  Currently, when I run the page, I get this error:

Microsoft JScript runtime error: Sys.InvalidOperationException: A control is already associated with the element.

Does this look familiar?

Thanks for your help,

Terrance
