Use the FullRowSelect property to determine when the item or cell is selected. If the FullRowSelect property is exColumnSel, the SelectColumnIndex property determines the selected column. By default, the FullRowSelect property is exItemSel, and so the entire item is selected. If the FullRowSelect property is exRectSel property, the user can selects a range of cells by dragging. Use the Selected property to determine whether a cell is selected, if the FullRowSelect property is exRectSel. Use the SingleSel property to allow multiple items/cells in the selection. For instance, the FullRowSelect = True ( boolean value ) is the same as FullRowSelect = exItemSel, and FullRowSelect = False is the same as FullRowSelect = exColumnSel.
