Indeed, in order to achieve the behavior, you will have to change several control templates as the GridViewHeaderRow
contains both the column headers and the group headers. With this in mind, changing simply the height of the row would not work and you will need to review the control templates of the GridViewHeaderCell
and the CommonColumnHeader
and apply a few changes(possibly remove some elements as they are designed to fit in some minimum height). I see that you have decided to not take this path, but still, the following article might be of help - Edit Control Templates
- in case you decide to try this approach. Of course, you can always contact us if you have some more specific questions.
