    Sorry if this is a duplicate--couldn't find this question elsewhere...

    I would like my range RadSlider to only accept changes via dragging the handles, not by clicking on the track itself. What should I set to achieve this? I noticed that setting SmallChange and LargeChange to zero caused the slider to disappear. Here is my current definition:

    <telerik:RadSlider runat="server" ID="rslSol" IsSelectionRangeEnabled="True" Width="150" ShowDecreaseHandle="False" ShowIncreaseHandle="False" ThumbsInteractionMode="Push" EnableDragRange="False" TrackMouseWheel="False" OnClientValueChanged="rlsSolSlideChanged" OnClientSlideEnd="rslSolSlideEnd"></telerik:RadSlider>

    And here's how it looks (attached image):

    Hello Tom,

    It is not possible to disable the changing of the value of RadSlider when you click on its track out-of-the-box. I have logged this feature request in our feedback portal so you can use the following item to track its status, vote for it and comment it: If this feature gains a lot of votes it will be considered for implementation.

    For the time being you can try the following customization to disable the clicking on the track:
    <script type="text/javascript">
        var $ = Telerik.Web.UI;
        $.RadSlider.prototype._originalonTrackMouseDown = $.RadSlider.prototype._onTrackMouseDown;
        $.RadSlider.prototype._onTrackMouseDown = function (evt) {


    Check out the Telerik Platform - the only platform that combines a rich set of UI tools with powerful cloud services to develop web, hybrid and native mobile apps.
