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).

In both cases, the controls are added to the controls collection for the cell.

The Grid View 'Grid View1' fired event Page Index Changing which wasn't handled.

Since it’s a Bound Field, the Text Box is going to be Control[0].

In this example, we’ll go through a fully featured Grid View with editing, deleting, selecting, sorting, and paging functionality that is manually bound and identify the limitations and some of the workarounds. 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.

The Grid View does know the events that should be used to implement them, so the exceptions shown above are thrown when you try to perform one of these operations, but you have implemented the appropriate event handler.

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.

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.

First, we’ll implement a method to databind the Grid View, which will be called whenever databinding needs to be performed.
