Ajax Control Toolkit
MultiHandleSlider Demonstration

One Handle

A single-handled slider is still fully supported. This example borrows from the original Slider implementation, showing a horizontal slider ranging from -100 to +100 with 5 discrete steps in between, bound to an asp:Label control. The example is set up to trigger a postback when the asp:Label's value changes.

Two Handles - Vertical

This vertical slider has multiple handles and uses drag and hover effects. It also supports animation. Clicking on the outer rail will move the closest handle.

Three Handles - Horizontal

This slider has three handles, showing that you can declare as many handles as fit your needs. It also demonstrates visibly distinguishing the inner range from the outer rail.

Two Handles - Custom

This dual slider demonstrates how you can use sliding doors custom styling to achieve a popular slider skin effect, where the inner range is visibly contrasted against the selectable total range. You can drag between the two slider handles to move the entire inner range, and use the arrow keys or mouse wheel while hovering over the slider to change its values.
MultiHandleSlider Description
The MultiHandleSlider extender provides a feature-rich extension to a regular asp:Textbox control. It allows you to choose a single value or multiple values in a range through a graphical slider interface. It supports one handle, dual handles, or any number of handles bound to values of the asp:TextBox or asp:Label controls. It also provides options for read-only access, custom graphic styling, hover and drag handle styles, as well as the mouse and keyboard support for accessibility.

MultiHandleSlider Tips
  • TextBox visibility. The asp:TextBox that the MultiHandleSlider is upgrading will be visible during the page loading, so it is usable if JavaScript is not enabled on the browser. Depending on your requirements, you can prevent the asp:TextBox from being visible by setting its display mode to "none".
  • Inline - Block. While the TextBox is rendered as an inline element, the MultiHandleSlider will be rendered as a block element. Consider using floats or a table when designing that portion of the layout. The CSS inline-block display mode is not supported by Internet Explorer 6.
  • CSS. When using custom CSS classes for the MultiHandleSlider's rail and handles, it's recommended to specify positioning. The rail should have position:relative while the handle should have position:absolute. Also, ensure you set the z-order for handles higher than the rail so that they appear in front of the rail.
