Question

I’m currently migrating from WinForms over to WPF and I’m really struggling with the binding aspects. All i need to do is match the fill property of a rectangle to a textblock.background and keep them in sync. I know I can do this with ‘classic’ event handlers, but I have 24 textboxes and 24 rectangles, and I’d prefer a more WPF solution. I’ve toyed with the binding properties but I can’t seem to get any type of results since I have no clue with type of binding I even need! Do i need an event, or use a convertor, or possibly a style trigger? Maybe just stick transparent tape on the screen and call it a day?

I know the following doesn’t work but this is my level of understanding at this point.

<Rectangle Fill="{Binding Source="textBlock.Background"} />

I’ve read various articles on databinding but they are all much more advanced, and typically deal with data.

Can someone please shed some light on this helpless n00b!

Answer 1

<TextBlock x:Name="SomeTextBlock" Content="Hi"/>
<Rectangle Fill="{Binding ElementName=SomeTextBlock, Path=Background}"/>

That’s the easy way if you are creating them in XAML.
