You can do things like this in a GridControl and a GridDataBoundGrid. It can also be done in simple flat GridGroupingControls. But in a GridGroupingControl with nested tables where the only selection architecture supported is the Table.SelectedRecords collection, you can only have whole records selected. If you want such behavior in a arbitary GridGroupingControl, you would have to manage the whole process yourself.

Post the type of grid are you using and maybe we can post some specific code snippets if such selections are possible for your particular grid.

You can use the SelectionChanging and SelectionChanged events in a GridControl to control selections. To avoid a cell accepting focus, you need to set gridControl1[row, col].Enbled = false;. Here is a little sample illustrating the use of these events.

Hi again and thanks,
That is what I would like but
A) Clicking a cell in wholeSelectedRows does not make tha row become selected.
B) It does handle click and drag but nog shift and arrow keys although the selection becomes changed.

Try changing the if statement to

 if (e.Range != null && !e.Range.IsEmpty && (e.Reason == GridSelectionReason.MouseUp || e.Range.IsCells))
           

to see if that comes closer to what you need.

Hi thanks,
yes It gets me closer.
But the following does not get selected correct:
1) select 1D and use shift+ down key; row 3 does not get selected
2) select tow white cells, use arrow keys to move between selected cells: the selection should be only the cell you moved to as when you step out of the selected area.

Here is another example of how you can go about doing such things. To get the exact behavior you seek, you will have to tweak the code to get the behavior you want.

Hi again!
I need to combine this funcionality with the possibility to select multiple lines and display a popup menu that should apply to all the selected rows. The problem is that when right clicking one the clicked row gets selected.
Could you help me out with the multiline and right click combination.

Hi!
I really would appreciate help on this!
The myGrid_selectionChanging/Changed occurs before the myGrid_MouseDown event and the selection at right click is then lost.

How can I have this kind of selection and still get right click menu to work.
