I was following your posted example on adding a FilterAll button to the GridHeaderTemplate. I was wondering if it is possible to add a button the the FilterMenu instead that would perform the same functionality?
I can't seem to find a way to add an item to the Gridfilter menu.
Thank you for your response Shinu. I used the code you supplied. I see that it adds the menu item to the FilterMenu collection, but the button doesn't appear anywhere on the Filter Menu. Is there another setting I should be aware of?
