TCustomGrid.Selection property
Rectangle with the current cell selections in the grid control.
Declaration
property Selection: TGridRect read GetSelection write SetSelection;Description
Selection is a
TGridRect property with the column and
row numbers for the current cell selection in the grid control. The Left and
Right members in the property value are column numbers for the cells in the
selection. The Top and Bottom members in the property value are row numbers
for the cells in the selection.
Selection is used when goRangeSelect has been included in the
Options for the grid.
When a new grid rectangle is assigned for the property, the member values in
the rectangle are normalized to ensure they are in the acceptable range of
values for the grid control. If all four members have negative values, the
current Selection is cleared by calling ClearSelection.
Column or row numbers in the rectangle are adjusted to exclude
FixedCols and FixedRows.When
goSelectionActive has been included in the grid Options, the
current selection is extended to include the new selection range. The
Invalidate method is called to redraw the grid control with the
new Selection value.
A value assigned to Selection is ignored when goRangeSelect has
not been included in the Options for the grid.
