How to a add a command to a WPF TextBlock?

Question

I'd like to be able to click a textblock and have it run a Command. Is this possible? (if not do I just somehow make a tranparent button over it or something?)

Solution 1

You can use a InputBinding.

<TextBlock Text="Hello">
    <TextBlock.InputBindings>
        <MouseBinding Command="" MouseAction="LeftClick" />
    </TextBlock.InputBindings>
</TextBlock>

Edit: Hyperlink is probably worth a mention too.

<TextBlock><Hyperlink Command="" TextDecorations="None" Foreground="Black">Hello</Hyperlink></TextBlock>

Solution 2

You do not make a transparent button over it, you put the TextBlock into it:

<Button>
    <Button.Template>
        <ControlTemplate TargetType="Button">
            <ContentPresenter />
        </ControlTemplate>
    </Button.Template>
    <TextBlock Text="Lorem Ipsum"/>
</Button>

This would quite great if it did not fire on mouse down, still +1 though for simplicity...

Yeah, MouseBinding can be a bit limited at times. The Hyperlink method I added executes on MouseUp

Awesomesausage! I just changed it to LeftDoubleClick and got exactly what I needed!

You may also add MinHeight="0" to button.
