Templates allow controls to make portions of their user interface
configurable. Templates are used in classes like
System.Web.UI.WebControls.DataList and can be
added in your own custom controls by declaring properties of type
ITemplate (for example, an ItemStyle or
HeaderStyle property). This allows the user to specify a template for
a portion of your control.
Your custom control code uses a supplied template by invoking the
InstantiateIn( ) method. This method accepts a
control reference and populates its
Control.Controls collection with one or more
server controls that represent the user interface defined in the
template. The control you supply to the InstantiateIn(
) method could be the current control, or one of the
current control's children. Note that you do not
need to write the implementation code for this method, as the .NET
framework provides it intrinsically.
public interface ITemplate {
// Public Instance Methods
public void InstantiateIn(Control container);
}
