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.
How to get the latest service release - Infragistics Community
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.
Hi Mike,
We have upgraded to the latest service release (11.1.20111.2042) and are still getting the same exception.
is this the latest service release ? (11.1.20111.2042)
That is the latest service release, so if you are still experiencing the exception with that version, then you must be running into a different issue.
Are you sure all of the projects in the solution are using the service release?
Can you post a small sample project demonstrating the exception?
