    Setting a Multiple Option Cell
    In This Topic

    You can define multiple option buttons in a multiple option cell. This cell type offers several option buttons, either horizontally or vertically, for the user to select. Only one button can be selected at a time. The default is for none of the buttons to be selected.

    Orientations of Options Buttons

    To create a cell that acts like a list of multiple option buttons, use the MultiOptionCellType class. Create a multiple option cell using the following procedure.

    Customizing Display and Operation

    You can customize the display and operation of the multiple options in the cell by setting the following properties.

    Property Description
    BackgroundImage Sets the background image for the cell.
    EditorValue Sets which value is written to the underlying data model.
    ItemData Sets the ItemData to use for the list.
    Items Creates the list to use for the option buttons.
    Orientation Sets the orientation of the option buttons.
    Picture Customizes the option button images.
    TextAlign Sets how text aligns in the cell.
    UseMnemonic Sets whether access keys (hot keys or keyboard shortcuts) are used in the cell.

    For more information on the properties and methods of this cell type, refer to the MultiOptionCellType class.

    For more information on the corresponding event when a user clicks on an option, refer to the FpSpread.ButtonClicked event.
