Build a templated ASP NET WebControl

I need a templated WebControl that I could use as following: <MyControls:VControl> <TitleConfiguration ValidatedValueControlID="lbl1" /> <Title>Html and nested controls can go here<asp:Literal ID="lbl1"></Literal></Title> <NoResultsMessage>Html and nested controls can go here</NoResultsMessage> <MessageConfiguration for="NoResultsMessage" CancelButtonText="Cancel"></MessageConfiguration> <IntermediateStateMessage1>Html and nested controls can go here</> <MessageConfiguration for="IntermediateStateMessage1" CancelButtonText="Go back"></MessageConfiguration> <IntermediateStateMessage2>Html and nested controls can go here</> <MessageConfiguration for="IntermediateStateMessage2" CancelButtonText="Go back"></MessageConfiguration> <CompletedMessage>Html and nested controls can go here</> <MessageConfiguration for="CompletedMessage" CancelButtonText="Cancel"></MessageConfiguration> </MyControls:VControl> Only one instance of <Title>, <TitleConfiguration> is allowed. Only one instance of <NoResultsMessage>, <IntermediateStateMessage1>, <IntermediateStateMessage2>, <CompletedMessage> is allowed. Multiple instances of <MessageConfiguration> are allowed. For attribute must have values selectable from an Enum. Class must have an associated custom ControlDesigner class. Only one template group is required. This template group should render <Title> ITemplate, then all defined <xxxMessage> ITemplates. Contents of each <xxxMessage> must be editable in Designer. When a new instance of the control is dragged into Design view, Visual Studio should generate default structure/contents as per above <MyControls:VControl> snippet.
