WPF datagrid column heading span more than once column

Question

In a WPF datagrid is it possible to group column headings?

What I\'m after is

| Column 1 | Column 2 | Column 3|
| a  b  c  | a  b  c  | a  b  c |
|          


        

Answer 1

Here is how I did it, entirely in XAML.

The width of the GD Column determins the width of each of the 4 columns, the UniformGrid sees to it that the columns are equal width. The TextBoxes stretch to full available width.

The coloring of the DG Cell (=4 TextBoxes) is replaced by the coloring (MouseOver) of the individual textboxes.
