Use the C1.Win.C1FlexGrid.C1FlexGridBase.RowSel and C1.Win.C1FlexGrid.C1FlexGridBase.ColSel properties to modify a selection or to determine which cells are currently selected. Columns and rows are numbered from zero, beginning at the top for rows and at the left for columns.
Setting the C1.Win.C1FlexGrid.C1FlexGridBase.Row and C1.Win.C1FlexGrid.C1FlexGridBase.Col properties automatically collapses the selection to a single cell, resetting the RowSel and ColSel properties. Therefore, to specify a block selection, you must Row and Col, then RowSel and ColSel. Alternatively, you may use the Select(CellRange,Boolean) method to select a range with a single statement.
When a range is selected, the value of C1.Win.C1FlexGrid.C1FlexGridBase.Row may be greater than or less than C1.Win.C1FlexGrid.C1FlexGridBase.RowSel, and C1.Win.C1FlexGrid.C1FlexGridBase.Col may be greater than or less than C1.Win.C1FlexGrid.C1FlexGridBase.ColSel. This is inconvenient when you need to set up bounds for loops. In these cases, you can use the Selection property to retrieve a normalized C1.Win.C1FlexGrid.CellRange object, where r1 <= r2 and c1 <= c2.
