I have a grid using RadGridView with grouping like below image.
I developed a context menu based on the GridViewHeaderCell.
Actually, I would have the behavior like that: When I click on an item of Context Menu (Expand All or Collapse All), it will expand/collapse only the sub-groups which are under the same group.
For example, in the image below, as I'm currently on the group "Cash" of group parent "Asset...Pictet & Cie (Suisse)", I expect that it will close all the groups under the group parent "Asset...Pictet & Cie (Suisse)" (like:Cash, Share, Bonds...) but let expanded other groups (like: group "Cash" under group parent "Asset...First Americain National Bank".
Is there any solution for that?
Many thanks for your help,
