Scrollbar to Selected Item When outlookbar is minnimized

[Ishita]

Hi, 
      When outlookbar is minimized and i click on it, it shows Selected Item. I have Radtree in it, But since list is pretty long , it does not display every item. How do i add VerticalScrollBar to it ? It can be seen in the image attached here.

May be is there any way to access width property of MinimizedContent Toggle Button!

Hello Ishita,

The RadOutlookBar doesn't have a property which controls the height (or width) of the popup of the MinimizedButton. However, in order to show a scroll you can wrap the RadTreeView in a ScrollViewer and set its MaxHeight property. Note that if you want the ScrollViewer to be styled corresponding to the applied theme you will need to base the scroll's style to the theme. Otherwise the scroll viewer will use the default Windows styles. Here is an example in code for this approach:

<UserControl.Resources>
    <telerik:Office_BlackTheme x:Key="officeBlackTheme" />

     <Style x:Key="style" TargetType="ScrollViewer" telerik:StyleManager.BasedOn="{StaticResource officeBlackTheme}" />
</UserControl.Resources>

....

<telerik:RadOutlookBar>
    <telerik:RadOutlookBarItem Header="Item 1" Name="item1">
        <ScrollViewer MaxHeight="600" Style="{StaticResource style}" >
            <telerik:RadTreeView>
                <telerik:RadTreeViewItem Header="Item 1" />
                <telerik:RadTreeViewItem Header="Item 2" />
                <telerik:RadTreeViewItem Header="Item 3" />
                .....
                <telerik:RadTreeViewItem Header="Item 30" />
            </telerik:RadTreeView>
        </ScrollViewer>
    </telerik:RadOutlookBarItem>
</telerik:RadOutlookBar>

Another approach could be to extract the ControlTemplate of the OutlookBar and set MaxHeight on the Popup of the MinimizedButton. You can see how to extract control templates in the Editing Control Templates help article.
