Create an ASP.NET page and add ScriptManager and UpdatePanel controls. Next, add a SqlDataSource and DetailsView control within the UpdatePanel and configure them so that the visitor can add new records to the Books table.

add two Label Web controls to this pageone outside the UpdatePanel and the other within the UpdatePanel. Have the Label Text properties assigned to the current date and time on each page load. When testing the page, note that when the page is first visited, the two Labels' values match, but when a new record is added through the DetailsView control, the Label within the UpdatePanel is updated, but one outside the UpdatePanel is not.

Extend the page created in the first exercise by adding a second UpdatePanel control. Drag a GridView control into this second UpdatePanel and bind it to the same SqlDataSource control used by the DetailsView. Also, add a Label Web control to this second UpdatePanel and configure it to display the current date and time on each page visit. What happens when a new record is added through the DetailsView control? What happens if you set the two UpdatePanels' UpdateMode properties to Conditional? Add a trigger to the second UpdatePanel so that it is updated only when a new record is added via the DetailsView control
