Hello, I have a RadRibbonGroup with content that I want to fill all available space in the group.
The content is intended to be more advanced, but in its most simple form it can be demonstrated with a textbox like this:
<telerik:RadRibbonGroup Header="My group" Width="200" Height="100">
<TextBox av:Text="Some text"/>
</telerik:RadRibbonGroup>
The size of the RadRibbonGroup is set dynamically but in the example is locked to a static size. In this case I want the content of the group (the textbox) to stretch in all directions. Vertically this works works as expected and the textbox is stretched by default and can be set to top, bottom, etc. with the VerticalAlignment property. However, everything i do horizontally seems to be ignored.
The attached image demonstrates how the code above looks and what I want it to do. How do I make this work?
