Programatically select one cell from grid which SelectionStyle(Extended)

[MegumiSawada]

Hi,

I'd like to select only one cell from the grid whose SelectionStyle property is set to "Extended".
How can I acheive it programatically?

The followings doesn't work as expected.
* Unselect all the selection
#Grid.Items<>.Selected
#Grid.Columns<>.Selected := Flase
* Try to select one cell
#Grid.Items<5>.Selected
#Grid.Columns<3>.Selected := True

I appreciate your kind advice.

Best Regards,
