Basic Selection

RadVirtualGrid provides you with a selection functionality, which allows the user to select one or more items (rows or cells) from the data displayed by the control.

Row Selection

To select an item in RadVirtualGrid click in the rectangle area of the desired row. By default the user can select only one row (the entire row is selected).

Cell Selection

You can modify RadVirtualGrid to select single cell instead of entire row by setting its SelectionMode property to CellSelect:


this.radVirtualGrid1.SelectionMode = VirtualGridSelectionMode.CellSelect;

Me.radVirtualGrid1.SelectionMode = VirtualGridSelectionMode.CellSelect

After setting this property, to select a cell in RadVirtualGrid, click the desired cell.

The following events will fire in case the selection is changed:

  • SelectionChanging: fires before the selection is changed.
  • SelectionChanged: fires after the selection is changed.
  • CurrentCellChanging: fires before the current cell is changed.
  • CurrentCellChanged: fires after the current cell is changed.
