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 : bool
Protected ReadOnly Property Initialized As Boolean
Property 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.
