    Using Touch Support with Selections
    In This Topic

    You can select columns, rows, cell ranges, and the entire control using touch gestures.

    The selection gripper is displayed when touching the cell, column, or row. The gripper is not displayed when using the mouse or keyboard. The selection grippers are displayed on the outside edge of the range (top-left and bottom-right edges, by default). The border is displayed around the selected cell range when using touch operations.

    Tap a cell to select the cell and display the selection gripper. Press the cell selection gripper and slide. Release to select a cell range.
