This article is one in a series of articles on ASP. In particular, we look at enabling editing support in the Grid View. This article focuses on the Sql Data Source control; for a detailed look at updating with the Object Data Source, refer to the "Editing, Inserting, and Deleting" tutorials in my Working with Data in ASP. Let's explore the updating "action" for the Access Data Source and Sql Data Source controls in more detail.

NET 2.0 introduces three new data Web controls: the Grid View, the Details View, and the Form View.

In particular, Bound Fields turn into Text Box Web controls; Check Box Fields, which are displayed as unclickable checkboxes in the read-only status, become clickable.

This interface allows the user to make changes to the selected row's values.

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.

NET 2.0 introduced a number of new Web controls designed for accessing and modifying data. NET 2.0's data source controls make it possible to retrieve, insert, update, and delete data without having to write the tedious dedata access code that was so commonplace in ASP. Previous installments of this article series have looked at returning, inserting, and deleting data using the Sql Data Source control. These controls can work in unison with the data source controls to facilitate inserting, updating, and deleting data.

These controls allow page developers to declaratively access and modify data without writing any code to perform the data access. In this article we will examine basics of using the Sql Data Source and Grid View controls to update records from a database.

When editing with a Grid View we'll specified (as our's does), then the Grid View's smart tag will include a checkbox titled "Enable Editing." Check this checkbox to enable editing.

Norwegians give birth, as well as throughout Europe, rather late, at the age of 30-40, when they have already achieved a lot in life and have the opportunity to devote themselves completely to children.
