After specifying the query, we add the appropriate sorting. When you bind a Grid View through a Data Source ID, the Grid View will update this value since it is internally tracking the sort expression, so it knows when to switch between ascending and descending.
We’ll revisit this method when we implement the sorting functionality.Once we have a reference to the Text Box, we set the new last name and save the changes (through the Submit Changes method).When a Bound Field is displaying data (not in edit mode), the appropriate text is added to the Text property of the appropriate cell.We’ll get to how these properties are populated shortly, but first we need to go back to the Bind Data method.The original method shown above did not implement any sorting, but now that we have a place to store the Sort Expression and Sort Direction we need to change that.We’re sorting on the appropriate field based on the Sort Expression, and setting the direction based on Sort Direction by calling either the Order By or Order By Descending methods. As with paging, we also reset the Edit Index and Selected Index when sorting.
Finally we need to populate the Sort Expression and Sort Direction when they change, and we’ll handle that in the Sorting event. Also like paging, so show that it does get called, databinding is handled in the Sorted Event ( First, we obtain the User ID of the affected row from the Grid View Data Keys collection, which we use to pull the appropriate record from the database.In addition to that, we’re resetting the Edit Index and Selected Index when the page is changed to avoid cases, for example, where you change pages and are suddenly editing a different item.Bind Data could be called in Page Index Changing, but to show that it the event is raised, we’ve handled that in Page Index Changed.If we were using a Template Field instead, the compiler translates the markup in the templates to the appropriate types of controls in the same way as the page markup in parsed.For this example, the Item Template would be transformed into a Literal control, and the Edit Item Template would be transformed into a Literal control, a Text Box, and a Literal control (the literal controls would include the spacing between the Edit Item Template tags and the Text Box tags).NET 2.0 most of the examples and tutorials deal with setting the Data Source ID, which buys you a lot of automation that you may not even appreciate unless you’ve done this the old fashioned way.
