I have an UltraGrid located on the first tab of an UltraTabControl. When I add a UserControl to the RowEditTemplate, design mode breaks. Whats the deal? If you stick with built in controls either infragistics or MS, all is fine.
Here is a pic of the error message:

When I remove the UserControls from the RowEditTemplate, design mode works again. Is there some kind of bug here?

Hi Ken,
This error message doesn't say much, and you didn't post the call stack, so it's hard to guess what's happening here.
Can you post a small sample project demonstrating the error so we can check this out? You can attach files to your posts on the Options tab.
So here is the fix. I removed the databinding generated code from the designer file and into the forms constructor....like so.
public AnalysisProfileForm(){ InitializeComponent(); this.eligibleDaysFilters1.DataBindings.Add(new System.Windows.Forms.Binding("Days", this.ultraGridRowEditTemplate, "Days", true)); this.timeFormatter.DataBindings.Add(new System.Windows.Forms.Binding("TimeRange", this.ultraGridRowEditTemplate, "TimeRange", true)); this.DoubleBuffered = true; this.UpdateStyles();}
Here is the call stack and this only happens in design mode. When I have a custom User Control and I bind the control to the RowEditTemplate property....If I comment out the following line of code the error stops happening and design mode will render out.
this.timeFormatter.DataBindings.Add(new System.Windows.Forms.Binding( "TimeRange", this.ultraGridRowEditTemplate, "TimeRange", true));
