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.
The important point is not which of these two events call Bind Data, but one of them must or the Grid View will not be updated. When bound using a Data Source ID, the Grid View internally tracks the current Sort Expression and Sort Direction, and those are available through properties with the same names.
When you manually bind the Grid View, this tracking does not occur, so we must implement some mechanism for tracking those values.
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.
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.
For the Bound Field, we don’t know the ID of the Text Box since it’s autogenerated by the Bound Field, so we obtain a reference to it by getting the first control in the appropriate cell in the edited row.
You can see that in the case of a Template Field, the exact spacing within the control becomes significant, so it’s generally better to get a reference to the control by ID using Find Control than to use the Controls collection.
NET forums is how to deal with exceptions like The Grid View 'Grid View1' fired event Row Editing which wasn't handled.
The Grid View 'Grid View1' fired event Page Index Changing which wasn't handled.
The Grid View 'Grid View1' fired event Sorting which wasn't handled.
The Grid View 'Grid View1' fired event Row Deleting which wasn't handled. When I say manually databinding I mean not using a data source control specified as a Data Source ID, but rather setting the Grid View’s Data Source equal to the appropriate data object and calling Data Bind. NET 2.0 are familiar with how to deal with this, but since ASP.
