Hi,
We've just upgraded our project from using Infragistics v10.2 to v11.1 and have found that every one of our UltraDropDown controls used in a grid is throwing an exception at the EndInit() method in the designer:
The exception reads: "Control does not support transparent background colors."
Has anyone come across this before?
I've been through every line of code relating to the control, and there is no Transparency set to any of the appearance object or on the column settings.
Any idea's on how to fix this?
Cheers,
Craig
ohh, and if it helps, the exception stack trace reads:
Exception at System.Windows.Forms.Control.set_BackColor(Color value) at Infragistics.Win.UltraWinGrid.UltraGridBase.set_BackColor(Color value) at Infragistics.Win.UltraWinGrid.UltraGridLayout.SynchGridBackColor() at Infragistics.Win.UltraWinGrid.UltraGridBase.System.ComponentModel.ISupportInitialize.EndInit()
Hi Craig,
This is a known bug that was fixed. Get the latest service release.

Alternately, I think you may be able to work around this by explicitly setting the dropdown's DisplayLayout.Appearance.BackColor property to a specific color.
