On StackOverflow, I read an interesting WPF question:
Suppose you have a window with multiple buttons such as Ok/Cancel or Yes/No/Cancel.
All the buttons need to be the same width.
Several good answers had been given, but none mentioned the simplest technique - leveraging
constrain Grid columns to the same width.
In my answer to the question, I wrote:
Columns (and Rows) in a WPF Grid can automatically resize to fit their contents - when
SharedSizeGroupis used, columns with the same group name share their resizing logic.
There’s a simple XAML example included with my original answer - but for a fuller (interactive) solution, try the source code attached.
