en realidad es otra forma valida de lograr lo mismo.Suele suceder que a veces se necesita crear script con cierto dinamismo que solo se logra con código .net, de esta forma ese código javascript creado puede asignarse a un evento en un control para ser ejecutado.

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.

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.

The example shown here is for a Grid View, but the same types of event handlers must be implemented in roughly the same way for other data controls including the Form View, Details View, and List View. This is the final Grid View markup, so you can see the event handlers we’re going to implement.

We’ll start with binding data to the Grid View, then build up functionality from there.
