Working with Selections

You can select cells, rows, columns, or multiple ranges in the control. You can specify what the user is allowed to select with the SelectionPolicy property. You can further restrict the selection with the SelectionUnit property to a single row, column, or cell.

You can specify selection colors with the SelectionBorderColorSelectionBackground, or SelectionBorderThemeColor property.

Click and drag with the left mouse button to select a block of cells, columns, or rows. You can use the mouse click and Ctrl key to select multiple ranges of cells. Navigation keys are listed in the Using Keyboard Navigation.

The following image displays multiple selected blocks of cells:
