For the Template Field, we do know the ID of the control since we specified it in the markup, so we obtain a reference to it by calling Find Control on the appropriate row of the Grid View.

We can implement it in this way without a performance impact because the data is not actually retrieved from the database until required, so we can build up a chain of queries up to that point and only the end result will be pulled from the database. When manually databinding the Grid View, this will always show ascending, so we need to handle this manually with the following logic: After that we save the new Sort Expression.

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.

We’ll revisit this method when we implement the sorting functionality.

We also need force databinding to occur when then page is loaded, which we’ll handle in Page_Load.
