I have noticed this behavior as well, at first I though I was just doing something wrong, but after seeing this post I tested the following and found that when the Visual style on a True DB Grid is set to a 2007 style, the SelectedStyle.BackColor property is always desplaying as solid white. Below is the code where I am settting the style but it does not display correctly:
MyGrid.VisualStyle = C1.Win.C1TrueDBGrid.
VisualStyle.Office2007Blue;
MyGrid.SelectedStyle.BackColor = Config.clrGridSelect;
MyGrid.SelectedStyle.BackColor2 = Color.White;
MyGrid.SelectedStyle.GradientMode =
GradientModeEnum.Vertical;
When I switched the visual style back to system (MyGrid.VisualStyle = C1.Win.C1TrueDBGrid.VisualStyle.System;), then my SelectedStyle effects worked once agian.
Any thoughts on how this can be fixed or is this a bug?
