элемент управления-шаблон(An ASP.NET server control that does not itself provide a visual interface but allows its users (page developers) to supply templates that provide a visual interface. When the ASP.NET page parser encounters a templated control, it parses the control's template and dynamically creates child controls that supply the visual interface. The Repeater and DataList ASP.NET server controls are templated controls. The DataGrid control is not strictly a templated control, but uses templates to customize its user interface)
