Example

This sample overrides the virtual method DrawBackColor on UIElement. It calls the base implementation then draws a semi transparant hatch.

Imports System.Drawing
Imports System.Drawing.Drawing2D  
Imports Infragistics.Win

Protected Overrides Sub DrawBackColor(ByRef drawParams As UIElementDrawParams)
      
		' First Draw background.
       MyBase.DrawBackColor(drawParams)

		' Draw a hatch pattern over the control.
       Dim brush As HatchBrush = New HatchBrush(HatchStyle.Percent50, Color.White, Color.Transparent)

       drawParams.Graphics.FillRectangle(brush, drawParams.InvalidRect)
       brush.Dispose()

   End Sub

'Declaration
 
Protected Overrides Sub DrawBackColor( _
   ByRef drawParams As Infragistics.Win.UIElementDrawParams _
) 

 

using System.Drawing;
using System.Drawing.Drawing2D;	
using Infragistics.Win;

protected override void DrawBackColor(ref UIElementDrawParams drawParams)
{

	//First Draw background.
	base.DrawBackColor( ref drawParams );

	//Draw a hatch pattern over the control.
	HatchBrush brush = new Drawing2D.HatchBrush( HatchStyle.Percent50, Color.White, Color.Transparent );

	drawParams.Graphics.FillRectangle( brush, drawParams.InvalidRect );
	brush.Dispose();

}
