I'm using the grid to display a tree-like structure.
I want to allow user co-selection of certain rows with certain other rows, but not all combinations. i.e. siblings may be selected with one another, but not with children of other parent.
How do I cancel selection/activation before it occurs?
Thanks.
Hello,
We have cancelable events for this. To cancel Selection, you can use the SelectedItemsChanging event. If you want to cancel Activation, you can use the RecordActivating events.
Hope this helps.
