Column group header

[Rob]

Hi,

I'm trying to create a grid with only column group header but no individual column header.
I have added a picture to show what I'm trying to achieve. the + and - button are to add column.

I have created the grid and the column group headers but can't remove the individual column header.
Secondly can I set a minimum size for the column group header, so that if there are not enough column the header title is readable.

Any suggestions to solve my 2 issues would be greatly appreciated.

thanks

Hello Rob,

In order to remove the column headers without removing the column group headers you will need to edit the GridViewHeaderRow ControlTemplate. There you can comment out the Border with x:Name ="PART_GridViewHeaderRowBorder" and the DataCellsPresenter with x:Name="PART_DataCellsPresenter". 
As for your second question, you can put in the Header property of the GridViewColumnGroup a TextBlock element and set its TextWrapping property to "Wrap".

Also, I attached a sample project that demonstrates the suggested approach. It uses the NoXaml binaries with the implicit Themes. 
For more information you can check these articles:

• Setting a Theme (Using Implicit Styles)
• Editing Control Templates

I hope this helps.
