Creates a new ControlCollection object to hold the child controls (both literal and server) of the server control.
Assembly: System.Web (in System.Web.dll)
Override this method in a custom server control if you have created a collection object that is derived from the ControlCollection class. You can then instantiate that collection class in the override of this method.
The following code example overrides the method to create an instance of a CustomControlCollection class, which inherits from the ControlCollection class.
' Override the CreateControlCollection method to ' write to the Trace object when tracing is enabled ' for the page or application in which this control ' is included. Protected Overrides Function CreateControlCollection() As ControlCollection Return New CustomControlCollection(Me) End Function
The following code example uses the method in a custom server control override of the CreateChildControls method. The new collection is created, and then populated with two child controls, firstControl and secondControl.
Protected Overrides Sub CreateChildControls() ' Creates a new ControlCollection. Me.CreateControlCollection() ' Create child controls. Dim firstControl As New ChildControl() firstControl.Message = "FirstChildControl" Dim secondControl As New ChildControl() secondControl.Message = "SecondChildControl" Controls.Add(firstControl) Controls.Add(secondControl) ' Prevent child controls from being created again. ChildControlsCreated = True End Sub 'CreateChildControls
