Repeat a background brush in WPF

Repeat a background brush in WPF - wpf

and thank you.
This question is very similar to this old, unanswered question here:
How to paint notebook-like lines as TextBox background? However, it is not the same - not exactly.
I would like to create a notepad, lined paper-like background but I am not not familiar with how to repeat a brush in XAML. How do you?
EDIT
Here's the solution as part of a TextBox:
<TextBox TextBlock.LineHeight="20"
TextBlock.LineStackingStrategy="BlockLineHeight"
Padding="20,10,20,20" TextWrapping="Wrap">
<TextBox.Background>
<DrawingBrush TileMode="Tile" Stretch="None" Viewport="0,0,20,20"
ViewportUnits="Absolute" Opacity=".07">
<DrawingBrush.Drawing>
<GeometryDrawing>
<GeometryDrawing.Pen>
<Pen Brush="RoyalBlue" />
</GeometryDrawing.Pen>
<GeometryDrawing.Geometry>
<LineGeometry StartPoint="0,0" EndPoint="20,0"/>
</GeometryDrawing.Geometry>
</GeometryDrawing>
</DrawingBrush.Drawing>
</DrawingBrush>
</TextBox.Background>

</TextBox>

<DrawingBrush TileMode="Tile" Stretch="None"
Viewport="0,0,20,20" ViewportUnits="Absolute">
<DrawingBrush.Drawing>
<GeometryDrawing>
<GeometryDrawing.Pen>
<Pen Brush="Gray"/>
</GeometryDrawing.Pen>
<GeometryDrawing.Geometry>
<LineGeometry StartPoint="0,0"
EndPoint="20,0"/>
</GeometryDrawing.Geometry>
</GeometryDrawing>
</DrawingBrush.Drawing>
</DrawingBrush>

Funny, was just doing the same thing. Here ya go. You will probably have to play with the TileMode to set the direction of the tiling, and the ViewPort, the last two numbers should be the width/height of your image (I had to do this because my image was being stretched or just not coming out right).
<ImageBrush x:Key="WindowBackground" ImageSource="/Images/Background.png" TileMode="Tile" ViewportUnits="Absolute" Viewport="0,0,4,4" />

Use an ImageBrush
<ImageBrush ImageSource="image.png" TileMode="Tile"/>

Wpf canvas grid with coordinates

I have following canvas Code:
<Canvas>
<Canvas.Background>
<DrawingBrush TileMode="Tile" Viewport="0,0,40,40"
ViewportUnits="Absolute">
<DrawingBrush.Drawing>
<GeometryDrawing>
<GeometryDrawing.Geometry>
<RectangleGeometry Rect="0,0,400,400"/>
</GeometryDrawing.Geometry>
<GeometryDrawing.Pen>
<Pen Brush="Red" Thickness="1"/>
</GeometryDrawing.Pen>
</GeometryDrawing>
</DrawingBrush.Drawing>
</DrawingBrush>
</Canvas.Background>
</Canvas>
This canvas generates a grid like you can find it on excel.Now I want to know if ist possible to generate the coordinates too. With cooridnates I mean that the first top row in the first fiels has a tiny text in it that says "A0" and the next one has "B0" and so every cell has coordinates like Excel.Would this be possible?

XAML graphic vector as image source

Now many graphics designers provide the images as xaml file not ico, png, ..., How can I use a xaml file as image source?
Thanks

From the MSDN
<Image>
<Image.Source>
<DrawingImage PresentationOptions:Freeze="True">
<DrawingImage.Drawing>
<GeometryDrawing>
<GeometryDrawing.Geometry>
<GeometryGroup>
<EllipseGeometry Center="50,50" RadiusX="45" RadiusY="20" />
<EllipseGeometry Center="50,50" RadiusX="20" RadiusY="45" />
</GeometryGroup>
</GeometryDrawing.Geometry>
<GeometryDrawing.Brush>
<LinearGradientBrush>
<GradientStop Offset="0.0" Color="Blue" />
<GradientStop Offset="1.0" Color="#CCCCFF" />
</LinearGradientBrush>
</GeometryDrawing.Brush>
<GeometryDrawing.Pen>
<Pen Thickness="10" Brush="Black" />
</GeometryDrawing.Pen>
</GeometryDrawing>
</DrawingImage.Drawing>
</DrawingImage>
</Image.Source>
</Image>
Instead of in-lining the GeometryDrawing you could refer to it as a static resource that you keep in a Resourcedictionary.
<Image>
<Image.Source>
<DrawingImage PresentationOptions:Freeze="True"
Drawing="{StaticResource myDrawing}">
</Image.Source>
</Image>
You will also find that you can show the drawing only once this way. So if you want this image to be present in the UI in multiple places, put the Image in a control template and style the controls with the template.

Thanks too all, this approach I know, my question was what happens when I have 100 xaml graphics files provided by a designer, now I have to extract the content from each file to move in a resource dictionary and set a key for each. I ask only if a more easy way as time.

Thank again too all.
I got a graphic like this
<Viewbox xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" Width="128" Height="128">
<Canvas Width="10240" Height="10240">

</Canvas>
</Viewbox>
This can be user very easy as a content to a Content control, but to youse this for a control which requires Image source I cannot I have to transform to:
<DrawingImage>
<DrawingImage.Drawing>
<DrawingGroup>
<DrawingGroup.Children>
<GeometryDrawing Geometry="M5986 6814l828 -828c124,-124 328,-124 452,0l2428 2428c124,124 124,328 0,452l-828 828c-124,124 -328,124 -452,0l-2428 -2428c-124,-124 -124,-328 0,-452z" Brush="#EDC87E">
<GeometryDrawing.Pen>
<Pen Thickness="1000" Brush="Blue"></Pen>
</GeometryDrawing.Pen>
</GeometryDrawing>
<GeometryDrawing Geometry="M6082 5442l412 412 -640 640 -412 -412c-534,401 -1197,638 -1916,638 -1764,0 -3194,-1430 -3194,-3194 0,-1764 1430,-3194 3194,-3194 1764,0 3194,1430 3194,3194 0,719 -237,1382 -638,1916zm-2556 -4471c-1411,0 -2555,1144 -2555,2555 0,1411 1144,2555 2555,2555 1411,0 2555,-1144 2555,-2555 0,-1411 -1144,-2555 -2555,-2555z" Brush="#808080"/>
</DrawingGroup.Children>
</DrawingGroup>
</DrawingImage.Drawing>
</DrawingImage>
The work in to trivial :(

DrawingBrush to WPF DataGrid cells as Background

I'd like to set a DrawingBrush to DataGridCelland I use
<DrawingBrush TileMode="Tile" ViewportUnits="RelativeToBoundingBox" Viewport="0,0,0.05,1">
<DrawingBrush.Drawing>
<DrawingGroup>
<GeometryDrawing>
<GeometryDrawing.Pen>
<Pen Brush="Gray" Thickness="0.05"/>
</GeometryDrawing.Pen>
<GeometryDrawing.Geometry>
<LineGeometry StartPoint="0,1" EndPoint="1,0" />
</GeometryDrawing.Geometry>
</GeometryDrawing>
</DrawingGroup>
</DrawingBrush.Drawing>
</DrawingBrush>
I have undesired result when DataGridCells have unequal widths like below.
How should I change the Brush so that regardles of the widht of the individual cells the result would look like this.

Change ViewportUnits from RelativeToBoundingBox to Absolute and adjust Viewport.
The coordinate system is not relative to a bounding box. Values are interpreted directly in local space.
Something like this:
<DrawingBrush
x:Key="DrawingBrush"
TileMode="Tile"
ViewportUnits="Absolute"
Viewport="0,0,5,15">
which looks like this

How to create a shape with a gradient fill, and add it to a border background in WPF

I am trying to create the following shape as a background to a border. You will notice that the bottom section on the shape has a linear gradient to it.
I have played around with lines and shapes and gradients, but i have not been able to apply the below to a border. nor can i get a shape that looks like that.
Is this even possible? if so, can anyone help

The below XAML produces a brush that looks similar to your picture. You should play around the colors, offsets, and the rest for the best appearance.
<DrawingBrush x:Key="br1" Viewbox="0,0,100,100" ViewboxUnits="Absolute" >
<DrawingBrush.Drawing>
<DrawingGroup>
<GeometryDrawing Brush="Lavender">
<GeometryDrawing.Geometry>
<RectangleGeometry Rect="0,0,100,100" />
</GeometryDrawing.Geometry>
</GeometryDrawing>
<GeometryDrawing>
<GeometryDrawing.Brush>
<RadialGradientBrush GradientOrigin="0.5,0.01" Center="0.5,-0.2" RadiusX="100">
<GradientStop Color="MidnightBlue" Offset="1.0" />
<GradientStop Color="LightSteelBlue" Offset="0.0" />
</RadialGradientBrush>
</GeometryDrawing.Brush>
<GeometryDrawing.Geometry>
<EllipseGeometry Center="60,310" RadiusX="160" RadiusY="300" />
</GeometryDrawing.Geometry>
</GeometryDrawing>
</DrawingGroup>
</DrawingBrush.Drawing>
</DrawingBrush>
Have fun!

Background with several paths

Is there a way I can put a background like this in a border:
The problem in there is that both the circle and the square must be a path (in my real problem I actually have 3 paths and they're gradients), and this makes it extremely problematic to resize, align, etc. I saw this solution but I had already tried using a viewbox and it didn't solve my problem.
Is there a way I can combine both the square and the circle into a path and keep the colors, and then set it as a background?
I don't have the real button around here, so I'll post it tomorrow, but it has several gradients to make some glossy effect and some Bezier curves to make the effect more "realistic". In the mean time the effect looks something like this:
Thanks for any help.

Don't quite understand why the ViewBox would not work but alternatively you can use a DrawingBrush, e.g.:
<Border Width="300" Height="300">
<Border.Background>
<DrawingBrush>
<DrawingBrush.Drawing>
<DrawingGroup>
<GeometryDrawing Brush="Blue">
<GeometryDrawing.Geometry>
<RectangleGeometry Rect="0,0,100,100" />
</GeometryDrawing.Geometry>
</GeometryDrawing>
<GeometryDrawing Brush="Red">
<GeometryDrawing.Geometry>
<EllipseGeometry Center="50,50" RadiusX="35" RadiusY="35" />
</GeometryDrawing.Geometry>
</GeometryDrawing>
</DrawingGroup>
</DrawingBrush.Drawing>
</DrawingBrush>
</Border.Background>
</Border>
