FrameworkContentElement.IsLoaded Property

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

Namespace:  System.Windows
Assembly:  PresentationFramework (in PresentationFramework.dll)

public function get IsLoaded () : boolean
You cannot set this property in XAML.

Property Value

Type: System.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.

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.

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();
}

Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003
