Hello, Kevin,
Reading through your posts it seems that you need help with RadDropDownList:
To change the color of selected item in the drop down you can use the VisualListItemFormatting event: Formatting Items - RadDropDownList - Telerik UI for WinForms
void radDropDownList1_VisualListItemFormatting(object sender, VisualItemFormattingEventArgs args)
{
if (args.VisualItem.Selected )
{
args.VisualItem.DrawFill = true;
args.VisualItem.BackColor = Color.DarkBlue;
args.VisualItem.GradientStyle = GradientStyles.Solid;
}
else
{
args.VisualItem.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
args.VisualItem.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
args.VisualItem.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
}
}Here you can find also useful information about how to access and customize elements: Accessing and Customizing Elements - RadDropDownList - Telerik UI for WinForms
The following code snippet demonstrates how to access the arrow button element and change its color:
this.radDropDownList1.DropDownListElement.ArrowButton.Fill.BackColor = Color.Aqua;I hope this information helps. If you have any further questions, please let me know.

{
RadMenuItem item = sender as RadMenuItem;
item.FillPrimitive.BackColor = Color.Blue;
}

{
RadMenuItem menuItem = sender as RadMenuItem;
menuItem.FillPrimitive.BackColor = Color.Green;
}
RadMenucontrol and found that it has the same issue as theRadDropDownListandRadSpinEditorcontrols. When the mouse hovers over it, it displays the same color as the other controls. Can this be modified uniformly? Thank you.
