Collapsing

RadRibbonView supports collapsing, which means that the ribbon may automatically collapse to save space when the application is resized to a smaller size.

Properties

The following properties are related to the collapse functionality:

  • RadRibbonView.IsCollapsed - gives you information about the current state of the RadRibbonView control. The value of the IsCollapsed property is True if the ribbon bar is collapsed. Respectively - False, if the ribbon is not collapsed. The RadRibbonView's IsCollapsed property is read-only.

  • RadRibbonView.CollapseThresholdSize - allows you to control the size under which the RadRibbonView will collapse.

        <telerik:RadRibbonView x:Name="radRibbonView" CollapseThresholdSize="100,100">
            ...
        </telerik:RadRibbonView>
    

    Events

You can use the CollapsedChanged event to be notified when the ribbon collapse state is changed.

<telerik:RadRibbonView x:Name="radRibbonView" CollapseThresholdSize="100,100" CollapsedChanged="radRibbonView_CollapsedChanged">
 ...
</telerik:RadRibbonView>

private void radRibbonView_CollapsedChanged(object sender, Telerik.Windows.RadRoutedEventArgs e)
{
 RadRibbonView ribbonView = sender as RadRibbonView;
 bool isCollapsed = ribbonView.IsCollapsed;
}
Private Sub radRibbonView_CollapsedChanged(sender As Object, e As Telerik.Windows.RadRoutedEventArgs)
    Dim ribbonView As RadRibbonView = TryCast(sender, RadRibbonView)
    Dim isCollapsed As Boolean = ribbonView.IsCollapsed 
End Sub
