PostBack.Handlers are copied onto the created controls, if they contain a matching command binding. * We map postback handlers onto the command bindings set on the CompositeControl by comparing the EventName and property name * For each control returned from GetContents, we enumerate its command bindings and compare them to the command bindings found on the CompositeControl. * If a matching command binding is found, we clone its postback handlers onto the child control. EventName is adjusted to match the new property name The control enumeration is done recursively before adding the control to Children, thus walking only through the tree created in this CompositeControl - nested CompositeControls, initialized Repeaters, ... are not included. In order to support templatws created in the CompositeControl, we recurse into CloneTemplates. For DelegateTemplate or any other more advanced needs, a protected CopyPostBackHandlersRecursive method is provided. resolves #1699
