[Solved] radgrid Javascript errors

[steve]

I have the grid in a user control in the default page (which has a master page).  Once I bind the control the the dataview, if I do any thing out side of the control, do any of the client side functionality, close the control, rebind or try to clear the control I keep getting this javascript runtime error.  I cannot find anything on the web about this error.  What am I missing. 

Microsoft JScript runtime error: 'this._owner.MasterTableView.get_element().offsetWidth' is null or not an object

I have grouping, sorting, resizing, column reorder and exporting enabled.

Thanks

I did figure out that the error goes away when I remove scolling.  So if any one can tell me what i need to enable scrolling or if there is more too it then enabling the property. 

Thanks

Looks like it was the was the loading panel.  I removed this panel and turn the scrolling back on and it the error went away.
