FocusPrimitive
Updated on Aug 4, 2026
FocusPrimitive supplies user interface cues that an element has received focus. The constructor for FocusPrimitive takes a BorderPrimitive that provides the basic dimensions. Fore colors and inner colors may be set explicitly or default control colors are used.
Creating a FocusPrimitive
C#
public class MyFocusPrimitiveElement : RadElement
{
protected override void CreateChildElements()
{
BorderPrimitive borderPrimitive = new BorderPrimitive();
borderPrimitive.Class = "MyBorderPrimtiveClass";
borderPrimitive.BoxStyle = BorderBoxStyle.SingleBorder;
borderPrimitive.Width = 3;
borderPrimitive.ForeColor = Color.Red;
borderPrimitive.GradientStyle = GradientStyles.Solid;
FocusPrimitive focusPrimitive = new FocusPrimitive(borderPrimitive);
this.Children.Add(borderPrimitive);
this.Children.Add(focusPrimitive);
base.CreateChildElements();
}
}
