ControlCollection.Clear Method ()
Removes all controls from the current server control's ControlCollection object.
Assembly: System.Web (in System.Web.dll)
The following code example demonstrates overriding the Control.CreateChildControls method, and using the method to delete all child controls previously in the ControlCollection object. In this case, you must do this so that outdated objects in your control's ControlCollection are not displayed inappropriately.
' Override to create repeated items. Protected Overrides Sub CreateChildControls() Dim O As Object = ViewState("NumItems") If Not (O Is Nothing) ' Clear any existing child controls. Controls.Clear() Dim I As Integer Dim NumItems As Integer = CInt(O) For I = 0 To NumItems - 1 ' Create an item. Dim Item As RepeaterItemVB = New RepeaterItemVB(I, Nothing) ' Initialize the item from the template. ItemTemplate.InstantiateIn(Item) ' Add the item to the ControlCollection. Controls.Add(Item) Next End If End Sub
