Similar to the look of graph paper, I want to draw straight lines of different colors on the Background of a Canvas to form a grid. The following code works fine for drawing only red lines. I also want to draw some Blue lines and gray lines. That means I need two more sets of lines, and so far I've not been able to solve the issue of drawing new sets of lines of additional colors.
<Window x:Class="GridTest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="700" Width="1000">
<ScrollViewer HorizontalScrollBarVisibility="Visible">
<Canvas Width="10000" Height="10000">
<Canvas.Background>
<DrawingBrush Stretch="None" TileMode="Tile"
Viewport="0,0 100,100" ViewportUnits="Absolute">
<DrawingBrush.Drawing>
<GeometryDrawing>
<GeometryDrawing.Geometry>
<GeometryGroup>
<LineGeometry StartPoint="0,0" EndPoint="0,100"/>
<LineGeometry StartPoint="0,0" EndPoint="100,0"/>
</GeometryGroup>
</GeometryDrawing.Geometry>
<GeometryDrawing.Pen>
<Pen Thickness="1" Brush="Red"/>
</GeometryDrawing.Pen>
</GeometryDrawing>
</DrawingBrush.Drawing>
</DrawingBrush>
</Canvas.Background>
</Canvas>
</ScrollViewer>
</Window>
To reiterate...this code is doing what I want for single color. But I also want to add lines of different colors.
