FrameworkContentElement.IsLoaded Property


Gets a value indicating whether this element has been loaded for presentation.

 property bool IsLoaded { bool get(); };
public bool IsLoaded { get; }
member this.IsLoaded : bool
Public ReadOnly Property IsLoaded As Boolean

Property Value


true if the current element is attached to an element tree and has been rendered; false if the element has never been attached to a loaded element tree.


The following example code uses IsLoaded as a conditional check to assure that a function displayData (not shown) will have valid elements loaded on the page to work against, as part of an on-demand handler. That same logic is run as an event handler for Loaded.

private void OnLoad(object sender, RoutedEventArgs e)
private void updateSummary(object sender, RoutedEventArgs e)
    if (myflowdocument.IsLoaded)
Private Sub OnLoad(ByVal sender As Object, ByVal e As RoutedEventArgs)
End Sub
Private Sub updateSummary(ByVal sender As Object, ByVal e As RoutedEventArgs)
    If myflowdocument.IsLoaded Then
    End If
End Sub


From a newly constructed instance, this property starts off false, and remains true once it is set to true, even if subsequently removed by code.
