Example

This sample overrides the virtual method DrawForeground of UIElement. Here we are filling the control Rect with the System.ControlLight color, and outlining it using ControlDark.

Visual Basic

Imports Infragistics.Win

Protected Overrides Sub DrawForeground(ByRef drawParams As UIElementDrawParams)
       
       ' We are going to draw the foreground ControlLight
       ' with a ControlDark border.
       Dim Brush As SolidBrush = New SolidBrush(SystemColors.ControlLight)

       Dim colorRect As Rectangle = Me.Rect

       colorRect.Inflate(-3, -3)
       drawParams.Graphics.FillRectangle(Brush, colorRect)

       colorRect.Width -= 1
       colorRect.Height -= 1

       drawParams.Graphics.DrawRectangle(SystemPens.ControlDark, colorRect)

       Brush.Dispose()

End Sub

C#

using Infragistics.Win;

protected override void DrawForeground(ref UIElementDrawParams drawParams)
{

	// We are going to draw the foreground ControlLight
	// with a ControlDark border.
	SolidBrush brush = new SolidBrush(SystemColors.ControlLight );

	Rectangle colorRect = this.Rect;

	colorRect.Inflate(-3,-3);
	drawParams.Graphics.FillRectangle(brush,colorRect);

	colorRect.Width--;
	colorRect.Height--;

	drawParams.Graphics.DrawRectangle(SystemPens.ControlDark,colorRect);

	brush.Dispose();
