Asp. Dynamic loading of template in net

Asp. NET, often use the templates (template) features, such as in Datagrid,datalist,repeater and other controls, the use of templates, will greatly enhance its functionality. In the past, when we were designing a program, we had already set the template in the control. However, sometimes, we may need to dynamically load templates, for example, when you ask your application's interface style to change with the user's needs, you need to go to the dynamic Loading template function. Note, however, that not all Web controls support the template feature, and note which controls support the functionality of the template, and some of the controls that support the template feature are listed below:
Repeater control, supported templates are:
HeaderTemplate, FooterTemplate, ItemTemplate, AlternatingItemTemplate, Seperatortemplate.
Datelist control, supported templates are:
HeaderTemplate, FooterTemplate, ItemTemplate, AlternatingItemTemplate, SeparatorTemplate, SelectedItemTemplate, EditItemTemplate.
The DataGrid control, supported templates are:
HeaderTemplate, FooterTemplate, ItemTemplate, EditItemTemplate, Pager.
Below, I'll show you how to dynamically load a template by dynamically loading the template for the DataList control:
The first step is to understand the principle of dynamic loading templates. In. NET, there is the TemplateControl class, which is the base class for page and UserControl classes. It also defines the basic functions of page and UserControl classes. This class provides two methods: LoadControl and LoadTemplate. The LoadControl method loads the control from the external file and returns the UserControl class object. The LoadTemplate method loads the template from the external file and returns the ITemplate object.
In the LoadTemplate method, there is only one parameter, the parameter value is the path to the external template file, and the ITemplate object is returned. The DataList control provides a series of properties that allow you to set properties for various templates, including AlternatingItemTemplate, EditItemTemplate, FooterTemplate, HeaderTemplate, ItemTemplate, SelectedItemTemplate, and Seperatortemplate, in the following section, will see the relevant introduction.
