BaseDataBoundControl.Initialized Property

Gets a value indicating whether the data-bound control has been initialized.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

'Declaration
Protected ReadOnly Property Initialized As Boolean

Property Value

Type: System.Boolean
true if the data-bound control has been initialized; otherwise, false.

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.

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 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
