The CExtGridWnd::Selection***() methods should be used for working with selections both in CExtGridWnd and CExtTreeGridWnd . Please note that in the CExtGridWnd , its methods use plain row indices while in CExtTreeGridWnd , HTREEITEM row handles are used in the vertical direction. You should use the CExtTreeGridWnd::ItemGetByVisibleRowIndex() and CExtTreeGridWnd::ItemGetVisibleIndexOf() methods for performing conversions. The CExtTreeGridWnd::ItemGetByVisibleRowIndex() method can convert any valid plain row number in the range 0 to CExtGridWnd::RowCountGet()-1 into the corresponding HTREEITEM . The CExtTreeGridWnd::ItemGetVisibleIndexOf() method can return plain row indices of tree rows which do not have collapsed parent rows or otherwise it returns a negative index value.
