I do understand your point of view and agree with you, that without that feature, the RadSlider is just a basic slider control, that does not cover most of the scenarios in which people want to use it. So far, however, even though we had it on our ToDo list, we have had other tasks (features for other controls in the RadControls suite) that were with higher priority. The good news is that adding new functionality and reworking the rendering mechanism and the logic of RadSlider is one of our primary tasks for the Q2 2008 release. Some of the intended features that we have discussed for the RadSlider and have added to the plan for the Q, are the following:
- Marks for the values the slider takes
- The ability to set the width and height of the control in percents
- More flexible mechanism for determining the physical and logical length of the track (currently Length property sets the physical value and the logical length is being calculated based on MinValue and MaxValue properties)
- Two-thumb functionality.
