This two-part article series examines how to use Microsoft's ASP.NET AJAX to add a pop-up control to a GridView in order to display drill-down
detail information in a responsive and clean manner. In Part 1 we looked
at displaying the list of employees from the Northwind database in a GridView. This involved building an application architecture consisting
of a Data Access Layer (DAL) created via Typed DataSets and a Business Logic Layer (BLL) created as custom classes. We then created an ASP.NET
page that used a GridView and an ObjectDataSource to invoke the appropriate BLL method and display the results.
In this second and final installment we'll turn our attention to Ajax-ifying the GridView by adding the pop-up control to display the territories
coverred by the moused over employee. This will involve creating a dynamic populate page method that will be called asynchronously from the
browser when the user mouses over an employee. This call back to the web server will return the specified employee's list of territories, which
will then be displayed in the pop-up. Read on to learn more!
