Specifically, I need to find out how to stop the GanttGrid from deselecting all other nodes/rows when a cell is selected, and instead activate and start editing that cell.
This is the same procedure done for the WPF GridDataControl in this
blog post / sample.
I've tried using nearly the same code with GanttGrid.InternalGrid, but the GridSelectionChangingEventArgs args in the SelectionChanging event only ever has a Reason of SelectRange, and there are a couple of other major behavioural differences with the GanttGrid.InternalGrid that prevent it from working as-is with the sample code.
Any help would be much appreciated.
