'Docking' the grid

Hi Guys

I'm trying to use a DataGrid to replace a few listboxes. The listboxes are currently displayed in tab panels. To stretch the list boxes I use this:

<ListBox ItemsSource="{Binding Blah}" 
         Height="{Binding Path=ActualHeight, RelativeSource={RelativeSource FindAncestor, AncestorType=TabPanel, AncestorLevel=1}}" 
         Width="{Binding Path=ActualWidth, RelativeSource={RelativeSource FindAncestor, AncestorType=TabPanel, AncestorLevel=1}}">

If I try to set the height and width in the same way for a DataGrid I get an error saying the Width cannot be negative.

Looking at the sample app I can see the DataGrid is resizing but I'm blowed if I can figure out how this is done.

Any clues would be gratefully accepted!

Cheers

Doh, dont worry, figured it out. I use Height and Width not ActualHeight and ActualWidth.

<ms:DataGrid ItemsSource="{Binding Blah}" 
             Height="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=TabPanel, AncestorLevel=1}, Path=Height}" 
             Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=TabPanel, AncestorLevel=1}, Path=Width}" />

Cheers

Hmm, so, this is still not right. This doesn't work for PropertyGrid. What is the best technique for achieving a Dock.Fill type of behaviour?

Hello

I don't think you should be adding the DataGrid or PropertyGrid to a TabPanel. Are you meaning to add them to a TabControl instead? By putting a control into a TabItem of a TabControl, it will stretch to fill the available space by default (No need to set the width and height using bindings).

If this does not solve your problem, please send some more information about the layout you are trying to achieve. Some xaml code or/and screen shots will help.
