How to make scrollbar appear in RadPaneGroup

[Unisense]

Hi,

I am having trouble with the RadPaneGroup. When the panegroup is filled with panes no scroll buttons appear(see image).

I have given each pane a very long name so they fill everything, see my XAML below:

<telerik:RadDocking.DocumentHost>
    <telerik:RadSplitContainer >
        <telerik:RadPaneGroup Name="hostPaneGroup" OverflowMode="Scroll">
            <telerik:RadPane Name="instrumentsPane" Title="Settingsssssssssssssssfdddddddddddddddddddddddddddddds" telerik:RadDocking.SerializationTag="instrumentsPane" CanUserClose="False" ContextMenuTemplate="{x:Null}"/>
            <telerik:RadPane Name="calibrationPane" Title="Calibrationddddddddddddddddddddd" telerik:RadDocking.SerializationTag="calibrationPane" CanUserClose="False" ContextMenuTemplate="{x:Null}"/>
            <telerik:RadPane Name="commentsPane" Title="Commentffffffffffffffffffffffffffffffff" telerik:RadDocking.SerializationTag="commentsPane" CanUserClose="False"  ContextMenuTemplate="{x:Null}"/>
            <telerik:RadPane Name="ratesWithinPane" Title="Rates Withinffgggggggggggggggggggggggggggggg" telerik:RadDocking.SerializationTag="ratesWithinPane" CanUserClose="False" ContextMenuTemplate="{x:Null}"/>
            <telerik:RadPane Name="ratesWithinBetween" Title="Rates Betweenhhhhhhhhhhhhhhhhhhhhhhhhhhh" telerik:RadDocking.SerializationTag="ratesBetweenPane" CanUserClose="False" ContextMenuTemplate="{x:Null}"/>
            <telerik:RadPane Name="ratesVSConcentration" Title="Rates VS Concentrationjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj" telerik:RadDocking.SerializationTag="rateVSConcentrationPane" CanUserClose="False" ContextMenuTemplate="{x:Null}"/>
        </telerik:RadPaneGroup>
    </telerik:RadSplitContainer>
</telerik:RadDocking.DocumentHost>

I have set the OverflowMode="Scroll" and i have also tried different scroll modes using the property ScrollMode(Item, Pixel, ViewPort).

I dont understand why the scrolling functionality doesnt show. Have i done something wrong or am i missing something? :)

Hi, 

I have found a solution to the problem. 
If anyone has the same problem the solution was to set the property ScrollViewer.HorizontalScrollBarVisibility to Auto.
