Is it possible to have cells selection for a number of cells that span both rows and columns, whilst holding down the left mouse button - similiar to MS excel.
Im trying to implement a Multi select, where by selecting many cells within the planner, the cells are highlighted, and any items within the range are also selected.
Since posting this message above, Ive found an undocumented and published property.....
MyPlanner1.ContinuousSelect := True;
This allows the selection to be continous across the rows and columns.
I know need to select PlannerItems (and highlight there are selected eg Red Border), that are within the selection, posibly using a MouseMove event, therefore providing realtime feedback of item selection as the mouse moves.
You can retrieve the selection rectangle via Planner.GridControl.Selection: TGridRect To find the items in this rectangle, you'd then need to use Planner.Items.FindFirst() / Planner.Items.FindNext() for each of the columns within this selection rectangle.
