DEF VAR UIelem AS Infragistics.Win.UIElement.
DEF VAR mPoint AS System.Drawing.Point.
def var eMouse as System.Windows.Forms.MouseEventArgs.
/* UltraGrid column */
def var ucol as Infragistics.Win.UltraWinGrid.UltraGridColumn.
def var ucell as Infragistics.Win.UltraWinGrid.UltraGridCell.
eMouse = CAST( e, "System.Windows.Forms.MouseEventArgs" ).
mPoint = eMouse:Location.
UIelem = CAST( ultraGrid1:DisplayLayout:UIElement:ElementFromPoint( mPoint ),
"Infragistics.Win.UIElement" ).
/* get the column where the mouse click was */
ucol = CAST( UIelem:GetContext()
, "Infragistics.Win.UltraWinGrid.UltraGridColumn" ).
/* get the cell where the mouse click was */
ucell = ultraGrid1:ActiveRow:Cells[ucol:ToString()].
message ucol:ToString()
