    I have a slider defined as follows:

    <telerik:RadSlider ID="RadSlider1" runat="server" Value="0" MinimumValue="0" MaximumValue="50" AutoPostBack="true" Height="60px" Width="500px" ItemType="Item" ShowDecreaseHandle="false" ShowIncreaseHandle="false" TrackPosition="TopLeft" Skin="Simple">


    I populate a range of values in code behind as follows:

    myExcess As List(Of contractors.excess) = contractors.excess.GetByContractorID(Session("ContractorID"))


     For Each Excess In myExcess

     RadSlider1.Items.Add(New RadSliderItem(Excess.ExcessAmount, Excess.ExcessPercent))


    for this example, values witten are
    Text = 100, value =0.1
    Text = 200, value =0.2
    etc. etc

    The slider renders as expected, however, after clicking or dragging, the order of the items changes!
    It was initially: 100,200,300,400,500

    After a drag this may become 100,200,400,500,300

    There is no other clientside or server side code so I am puzzled!

    Same problem with IE and Chrome

    Can anyone help please?

    Hi Paul,

    The order of the items in the RadSlider depends on the order of the records in the data-source used for populating the control. I would suggest checking if the order in which the items come from the data-source is always the same and whether the slider is rebound every time a postback occurs.

    If you are still having difficulties, please send a simple, runnable page that isolates your case so that I can inspect it locally and provide a concrete solution.
