I'm developing a SharePoint application, using code-behind aspx pages. I've managed to get a WebGrid displaying data from a SharePoint list. When I try to instantiate an UltraGridRow, SharePoint throws an 'unknown error' exception. I've tried the identical code in a regular ASP.NET page with no problem.
I'm running NetAdvantage 2008 V 3, CLR 2.0
protected UltraGridRow MyActiveRow;
Here's the line of code that works in the ASP.NET app but crashes the SharePoint app:
this.MyActiveRow = new UltraGridRow();
Any ideas on what's causing the problem and what might be the cure?
