Hi!
I have a tri-state RadCheckBox and tried to change its intermediate state background color with the "SetThemeValueOverride", but nothing happens.
The code is the following:
checkBox.ButtonElement.CheckMarkPrimitive.CheckElement.GradientStyle = GradientStyles.Solid;
checkBox.ButtonElement.CheckMarkPrimitive.SetThemeValueOverride(FillPrimitive.BackColorProperty, Color.Black, "ToggleState=Intermediate", typeof(FillPrimitive));
What do I wrong?
Thank you,
Sandor
