How can I have a TextBox with text wrapping enabled not being "greedy" in size?

I guess the solution to my issue is easy, but it appears that I'm a blockhead at this time 😢

I want a TextBlock control to be serving as an informational item that's supposed to be as wide as the other controls demand. So, it's width is supposed to be "non greedy", using the width that's determined by the other controls in the DockPanel wrapping the text it holds as required.

It's supposed to look something like this, where I'm using the MaxWidth property do demonstrate the desired situation:

However, currently the TextBlock control doesn't wrap:

How can I have the TextBlock control use the width that's determined by the controls beneath?

Sounds like you have a MaxWidth of the dialog in mind because you are not happy with the very wide one, so why not just set MaxWidth on the dialog?

Otherwise I think you would have to derive from the TextBlock and in the MeasureOverride return zero. It might be a bit tricky with the height though.

Alternatively, you could databind the parent Border's width to Window.ActualWidth or similar

Thank you for replying!

Actually, the target application is multi-lingual, so the labels, button texts and TextBox content determine the final width.

I've set a MinWidth and a MaxWidth to the window to constrain the possible sizing range. The window size is supposed to fit somewhere in-between.

The heading TextBlock now is supposed to follow what all the other controls determine as their actual width. Is there perhaps something like a 2-pass measure option?

what about the databinding to windows' width, does that not do the trick?
