Aspxgridview rowupdating event not firing

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.

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.

When a Bound Field is displaying data (not in edit mode), the appropriate text is added to the Text property of the appropriate cell.

When the Bound Field is in Edit mode, things are a little different.

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).

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.

We’ll revisit this method when we implement the sorting functionality.

We also need force databinding to occur when then page is loaded, which we’ll handle in Page_Load.

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.
