We've now come to the conclusion that different groups of people are in charge of developing different technologies over at Microsoft. The WPF (Windows Presentation Foundation) development team made a significant number of improvements over Windows Forms and GDI+, but in the process missed a couple of things.
One very important item is the System.Drawing.HatchBrush from System.Drawing.Drawing2D which was very useful in Windows Forms but is now totally absent in WPF. We have made an interim replacement, which although does not use the win32 API directly should provide a remedy for most situations.
If used conservatively it should not have that much of an impact on the performance of your WPF applications.
WPF does not use the OnPaint override like GDI+. Instead you have to override the OnRender method. One important thing to note however is that WPF will disregard any drawing made to the DrawingContext unless the background mode is set to transparent, so the XAML for the Window should look like this:
<Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="404" Width="727" Background="Transparent"> </Window>
public partial class Window1: WindowThe HatchType and HatchStyle should look like this:
{
private DrawingContext mp_oGraphics;
public FillPattern()
{
InitializeComponent();
}
protected override void OnRender(DrawingContext drawingContext)
{
base.OnRender(drawingContext);
mp_oGraphics = drawingContext;
