Glossary Item Box

A slider cell displays a slider control in the cell.

To create a cell that acts like a slider, use the SliderCellType class and follow the procedure described in this topic.

Customizing the Slider

The parts of the slider (corresponding to their property names) are shown here. For this example, the orientation is horizontal and solid colors are used (as opposed to pictures).

Set the background image for the cell.

Note that some graphical elements in certain cell types are affected by XP themes (visual styles). Setting the VisualStyles property of the Spread component to "off" can allow visual customizations of those graphical cell types to work as expected. For more information, refer to Using XP Themes with the Component.

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

For more information on other graphical cell types, refer to Working with Graphical Cell Types.
