Gets a value indicating whether the data-bound control has been initialized.
protected:
property bool Initialized { bool get(); };protected bool Initialized { get; }member this.Initialized : boolProtected ReadOnly Property Initialized As BooleanProperty Value
true if the data-bound control has been initialized; otherwise, false.
Examples
The following code example shows a property that belongs to a derived data-bound control class. The example demonstrates how a data-bound control can call the OnDataPropertyChanged method if a property that identifies a data source is changed after the data-bound control is initialized. This code example is part of a larger example provided for the DataBoundControl class.
public string DataTextField {
get {
object o = ViewState["DataTextField"];
return((o == null) ? string.Empty : (string)o);
}
set {
ViewState["DataTextField"] = value;
if (Initialized) {
OnDataPropertyChanged();
}
}
}
Public Property DataTextField() As String
Get
Dim o As Object = ViewState("DataTextField")
If o Is Nothing Then
Return String.Empty
Else
Return CStr(o)
End If
End Get
Set(ByVal value As String)
ViewState("DataTextField") = value
If (Initialized) Then
OnDataPropertyChanged()
End If
End Set
End Property
Remarks
The ConfirmInitState and OnPagePreLoad methods both explicitly set the Initialized property to true. The ConfirmInitState method is called by the DataBoundControl.OnLoad method, while OnPagePreLoad is called when the PreLoad event is raised.
