FrameworkContentElement.IsLoaded Property

  • Reference

Definition

Namespace:
System.Windows
Assembly:
PresentationFramework.dll

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

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

Property Value

Boolean

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.

Examples

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)
{
    displayData();
}
private void updateSummary(object sender, RoutedEventArgs e)
{
    if (myflowdocument.IsLoaded)
        displayData();
}

Private Sub OnLoad(ByVal sender As Object, ByVal e As RoutedEventArgs)
    displayData()
End Sub
Private Sub updateSummary(ByVal sender As Object, ByVal e As RoutedEventArgs)
    If myflowdocument.IsLoaded Then
        displayData()
    End If
End Sub

Remarks

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.
