Extending the GridView Control
Like any other control in the ASP.NET Framework, if you don’t like any aspect of the GridView control, you always have the option of extending the control. In this section, you learn how to extend the GridView control with custom fields.
To create a custom field, you can inherit a new class from any of the existing fields or any of the following base classes:
• DataControlField—
The base class for all fields.
• ButtonFieldBase—
The base class for all button fields, such as the ButtonField and CommandField.
In this section, you learn how to create a long text field, a delete button field, and a validated field.
