This sample overrides the virtual method DrawFocus off of UIElement. Here we use ControlPaint to draw a focus rectangle around the specified rect.

Visual BasicCopy Code
Imports Infragistics.Win

 Protected Overrides Sub DrawFocus(ByRef drawParams As UIElementDrawParams)

' Get the rect inside bounding border.
     Dim rect As Rectangle = me.RectInsideBorders 

' Draw the focus rectangle using the ControlPaint class.
     ControlPaint.DrawFocusRectangle(drawParams.Graphics, _ 
	rect, drawParams.AppearanceData.GetForeColor(Me.Enabled), _
	drawParams.AppearanceData.GetBackColor(Me.Enabled))

 End Sub
C#Copy Code
using Infragistics.Win;
protected override void DrawFocus(ref UIElementDrawParams drawParams)
{

	// Get the rect inside bounding border.
	Rectangle rect = this.RectInsideBorders;

	// Draw the focus rectangle using the ControlPaint class.
	ControlPaint.DrawFocusRectangle(drawParams.Graphics,
										rect,drawParams.AppearanceData.GetForeColor(this.Enabled),
										drawParams.AppearanceData.GetBackColor(this.Enabled));

}
