I’m using a WPF DataGrid bound to a collection. One of the columns will be a ComboBox. I want the ComboBox to be editable, and also any changes to the text to be propagated to all other items in the collection that were previously using the same value.

I have this simple example program with 2 columns. The column on the left holds a datagrid, and the column on the right has a red rectangle in the middle. I want to make a binding, so that the width/height of the rectangle is always equal to the size of the biggest item in the list.
