Gridview edit not updating
Updating data through manually-created Web Forms is a bit more difficult and less practical because the Web controls that make up the updating interface must also be populated with the values of the record being edited.For example, to let a visitor edit a database record you first need to let them choose which record to edit.
What checking this checkbox does is add a Command Field to the Grid View's field list.When we examined inserting data and deleting data we looked at doing so both through manually-created Web Forms and through data Web controls, like the Grid View or Details View.In the manually-created Web Forms example for inserting, for example, we added Text Boxes, Drop Down Lists, and other Web controls to collect the values for the new record.To demonstrate this functionality, let's look at using a Grid View to list all of the records from the SELECT [Product ID], [Product Name], [Products].[Category ID], [Category Name], [Unit Price], [Discontinued] FROM [Products] INNER JOIN [Categories] ON [Products].[Category ID] = [Categories].[Category ID] ORDER BY [Product Name] can be specified through the data source's wizard, via the Select Query property in the Properties window, or declaratively.Previous installments in this article series have covered these steps in detail.
