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.
