Question

I am NEW to WPF. I have the following XAML code:

</Window>
        ...
    <Canvas>
        <TextBlock Canvas.Left="300" Canvas.Top="300">WORD1</TextBlock>
        <TextBlock Canvas.Left="350" Canvas.Top="300">WORD2</TextBlock>
        <TextBlock Canvas.Left="400" Canvas.Top="300">WORD3</TextBlock>
    </Canvas>
</Window>

I would like to define “300” as a resource (say “myTop”) and replace all Canvas.Top=”300″ with Canvas.Top=”myTop”.

How can I do this in WPF/XAML? I looked into StaticResources and DataTemplates, but could not figure out a simple way. Thanks.

First of all you have to add xmlns to the window

xmlns:System="clr-namespace:System;assembly=mscorlib"

And then define resource like this

<Window.Resources>
    <System:Double x:Key="theTop">300</System:Double>
</Window.Resources>

And then you can use it:

<Canvas>
  <TextBlock Canvas.Left="300" Canvas.Top="{StaticResource theTop}">WORD1</TextBlock>
</Canvas>
