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.
The required actions for paging to work are setting the new page index, setting the Data Source, and calling Data Bind (the last two through the Bind Data method).
We’ll start with binding data to the Grid View, then build up functionality from there.
First, we’ll implement a method to databind the Grid View, which will be called whenever databinding needs to be performed.
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).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.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.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.
