Ok, I have a call in to Infragistics as I really am having regular problems with these controls.
I am having to write code for just about all property value changes to these controls.

As a recent example, I wanted to use the UltraOptionSet but the item collection I added (Y - Yes and N - No) would not "stick". After a period of time rebuilding the app and debugging the item collection would reset to Yes - Yes and No - No which did not correspond to my dB bound column values of Y and N.
I had to write the following code for both binding and setting up the item collection:

        Me.VisitorLongNameUltraOptionSet.Items.Add("N", "No")
        Me.VisitorLongNameUltraOptionSet.Items.Add("Y", "Yes")
        Me.VisitorLongNameUltraOptionSet.DataBindings.Add _
            (New Binding("Value", VisitorDataset, "Visitors.VisitorLongNameYN"))

I had to write the following code to get my label's text to display at the bottom of the control:

        Me.VisitorLastNameUltraLabel.Appearance.TextVAlign = _
            Infragistics.Win.VAlign.Bottom
        Me.VisitorFirstNameUltraLabel.Appearance.TextVAlign = _
            Infragistics.Win.VAlign.Bottom

I cannot get any of the DisplayStyles to work (e.g. VisualStudio2005, Office2003, OfficeXP, Office2000).

This has been really frustrating as I have deadlines that are slipping while I have to write all this UI configuration code.

If anyone has any additional insights into what is going on I'd appreciated it.
