How to: Add DataList Web Server Controls to an ASP.NET Web Page
To add a DataList Web server control to an ASP.NET Web page
Use the Configure Data Source Wizard to define the connection and the query, or data-retrieval method, for the data source control.
If you want to use the DataList control to update data (for example, by writing code for the control's UpdateCommand or DeleteCommand event), you must be sure that the data source control is defined with appropriate queries and that the queries include a primary key. In the Configure Select Statement step of the Configure Data Source Wizard, you can click Advanced to display advanced options where you can have the wizard generate update queries.
In Design view, from the Data tab of the Toolbox, drag a DataList control onto the page.
Right-click the DataList control and click Show Smart Tag.
In Choose Data Source list, click the name of the data source control that you created in steps 1 and 2.
In Design view, right-click the DataList control, point to Edit Template, and then click Item Templates. The control displays the ItemTemplate, AlternatingItemTemplate, SelectedItemTemplate, and EditItemTemplate in template-editing mode.
Add to the templates any HTML text and other Web server controls or HTML server controls that you need. For detailed information about editing templates, see How to: Create Web Server Control Templates Using the Designer.
When you are finished editing the templates, right-click the DataList control and then click End Template Editing.
