BaseDataBoundControl.Initialized Property

Definition

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.
