Thumb positioning bug

[hwsoderlund]

I've experienced some weird behaviour when changing the width, the tick scale and the value of the slider simultaneously. The position of the thumb becomes erratic. The behaviour is very hard to describe in words. Try the code below and see for yourself. The weirdness appears when the first button is clicked.

    <Grid x:Name="LayoutRoot" Background="White">
        <StackPanel>
            <telerik:RadSlider x:Name="Sld01"

                               Minimum="1"
                                Maximum="10"
                               Value="3"
                                TickFrequency="1"
                                IsMoveToPointEnabled="True"
                                IsSnapToTickEnabled="True"

            <Button x:Name="Btn01" Content="5 steps, value 3, width 250"></Button>
            <Button x:Name="Btn02" Content="10 steps value 3, width 500"></Button>
        </StackPanel>

Hi hwsoderlund,

We have to admit about this bug in RadSlider, but I'm pleased to inform you it is already addressed. We just scheduled the next official update of the RadControls for Silverlight suite for Tuesday next week so you will be able to get this issue resolved with that update.

Thank you for pointing this out to us! I have updated your Telerik points.

Best wishes,
Konstantin Petkov
