Is it possible today in the GridView to provide a menu in the column header that will turn on and off summary functions for columns? I can provide a way for my users to do this, but if there is built in support I would like to use it.
Thanks Vlad. This is helpful, but unfortunately this places the controls to the left of the sort indicator. I suppose I will have to set the template for this control to get it to show as I would like.
