O exemplo a seguir demonstra uma versão substituída do CreateChildControls método . Nessa implementação, o controle composto exibe um TextBox controle entre dois controles literais que renderizam HTML.

// Override CreateChildControls to create the control tree.
 [System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Demand, Name="Execution")]
 protected override void CreateChildControls() {

     // Add a LiteralControl to the current ControlCollection.
     this.Controls.Add(new LiteralControl("<h3>Value: "));

     // Create a text box control, set the default Text property, 
     // and add it to the ControlCollection.
     TextBox box = new TextBox();
     box.Text = "0";
     this.Controls.Add(box);

     this.Controls.Add(new LiteralControl("</h3>"));
 }

' Override CreateChildControls to create the control tree.
<System.Security.Permissions.PermissionSetAttribute(System.Security.Permissions.SecurityAction.Demand, Name:="Execution")> _
Protected Overrides Sub CreateChildControls()
   
   ' Add a LiteralControl to the current ControlCollection.
   Me.Controls.Add(New LiteralControl("<h3>Value: "))
   
   
   ' Create a text box control, set the default Text property, 
   ' and add it to the ControlCollection.
   Dim box As New TextBox()
   box.Text = "0"
   Me.Controls.Add(box)
   
   Me.Controls.Add(New LiteralControl("</h3>"))
End Sub

Ao desenvolver um controle de servidor composto ou modelo, você deve substituir esse método. Os controles que substituem o CreateChildControls método devem implementar a INamingContainer interface para evitar conflitos de nomenclatura.
