[CLOSED] UserControlRendererConfig RenderModes

[michaeld]

I've found that UserControlRenderConfig.RenderModes do the following:

• Replace - replaces the parent control with the added control
• AddTo/InsertTo - replaces the parent's child with the new usercontrol

But there is no way to AppendTo or InsertWithin. The client may already have added a control or two on the client-side, but these will get overwritten with AddTo or InsertTo (because the server doesn't have access to these items). I should be able to click a button, and add an unlimited number of new controls to the client without replacing the ones on the client already present.
