ASP.NET GridView Control

ASP.NET GridView Control

In this tutorial you will learn about GridView Control, features of the GridView control, GridView supported field types and Creating a GridView control on a Page.

The GridView control is the official successor to the DataGrid control of yesteryears. It is no longer listed in the toolbox, even though it is supported by ASP.NET 2.0. All new projects would automatically use the GridView control. Though both these controls have a similar look and feel they are implemented differently as already explained in the earlier section of this tutorial. However, to reiterate some of the features of the GridView control let us list them:

• The GridView control is associated with the DataSource control through its DataSourceID property.
• In ASP.NET 2.0 there are several DataSource controls that are designed to work with different data sources.
• Enabling Editing and Deleting records in the GridView Control is as simple as setting the properties “AutoGenerateDeleteButton” and “AutoGenerateEditButton” as "True"
• GridView totally supports 6 field types, they are:

1. BoundField,

2. CheckBoxField,

3. ButtonField,

4. CommandField,

5. HyperlinkField,

6. ImageField and

7. TemplateField
