Use SlideIn/AutoHide to keep a pane expanded

[Zack]

Our ultimate goal is to have a pane - the "Zone Editor" be collapsed by default but fly out once a variable is set - we have achieved part of this behavior using the code segment below. However, when we lose focus on the pane, it flies away again, even if the IsActive variable is set to true. Is there a way to prevent this?

 

<telerik:RadSplitContainer InitialPosition="DockedRight" Orientation="Horizontal" >
    <telerik:RadPaneGroup Name="ZoneEditorPane">
        <zoneEditor:ZoneEditor IsActive="{Binding DataContext.IsZoneEditorVisible, ElementName=DockingControl, Mode=TwoWay}" AutoHideWidth="1075" />
    </telerik:RadPaneGroup>
</telerik:RadSplitContainer>

Hello Zack,

To achieve this behavior, you can create a custom flyout behavior, which will allow you to control how the unpinned pane behaves when the pane is activated/deactivated, the mouse enters/leaves, and when the mouse's left button is clicked. Additionally, you can also specify a timeout, by which the flyout will automatically close.

To do so, create a custom class, implement the IFlyoutBehavior interface, and introduce your custom logic to achieve the desired behavior. Then, set a new instance of the new custom flyout behavior to the FlyoutBehavior property of RadDocking. 

More information on the flyout behavior functionality, as well as how to create a custom one, can be found at the following link:

With this being said, I hope the provided information will be of help to you.
