IsFlyoutPaneDisplayed Property

Indicates if the pane is unpinned and currently displayed in a flyout.
Syntax
'Declaration
 
Public ReadOnly Property IsFlyoutPaneDisplayed As Boolean
public bool IsFlyoutPaneDisplayed {get;}
Remarks

This property returns False when the pane is collapsed into the tab area.

Example
The following code demonstrates the use of some of the flyout related properties and methods on the DockablePaneBase and DockableControlPane

Imports Infragistics.Shared
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinDock

Private Sub buttonFlyout_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles buttonFlyout.Click

    ' A control pane can be referenced by the index, key or
    ' control from the ControlPanes collection since that is a
    ' collection of all the DockableControlPane instances managed
    ' by the UltraDockManager.
    Dim pane As DockableControlPane = Me.ultraDockManager1.ControlPanes(Me.ultraDayView1)
    Me.ShowInFlyout(pane)

End Sub

Private Sub ShowInFlyout(ByVal pane As DockableControlPane)

    ' If its already showing and its the active pane, exit
    ' IsFlyoutPaneDisplayed is equivalent to comparing it
    If (pane.IsFlyoutPaneDisplayed AndAlso pane.IsActive) Then
        Return
    End If

    ' its not the active pane, we'll active it and exit

        If (pane.DockedState = DockedState.Floating) Then

        ' the unpinned tab area and activate it
        pane.Flyout(True, True)
