Remarks

The ContentTemplateContainer property enables you to programmatically add child controls to the UpdatePanel control without having to define a custom template that inherits from the ITemplate interface. If you are adding content to the UpdatePanel control declaratively or through a designer, you should add content to the ContentTemplate property by using a <ContentTemplate> element.
