The scenario that you want to implement is not quite clear. Please check the following examples, as they could help you achieve the desired functionality:
- The Items collection of RadSlider can be used in order to add and remove items on the server-side. The code sample below demonstrates this:
RadSliderItem sliderItem =
- The RadSlider control can be databound as shown in the online demo Slider / Databinding.
The approaches, shown above, can be utilized for modifying the items of the RadSlider control on your page. As stated in this help article, the slider control has a server-side event OnValueChanged, which is fired when the user changes the Value with the mouse or mouse wheel. You can use this event to detect a handler click and to execute your logic.
