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.At that point we need to get the new values so we can update the record, which is done slightly differently for the Bound Field and the Template Field.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.After specifying the query, we add the appropriate sorting.

Sql Data Source, Object Data Source, Linq Data Source, etc) specified in a Data Source ID, the Grid View can automate many functions because, through the data source control, the Grid View on its own can perform the following operations: When you manually bind data to a Grid View, the Grid View itself cannot perform these operations, so they must be implemented in your code.
