GridView::AutoGenerateColumns Property

Gets or sets a value indicating whether bound fields are automatically created for each field in the data source.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public:
virtual property bool AutoGenerateColumns {
	bool get ();
	void set (bool value);
}
<asp:GridView AutoGenerateColumns="True|False" />

Property Value

Type: System::Boolean
true to automatically create bound fields for each field in the data source; otherwise, false. The default is true.

When the AutoGenerateColumns property is set to true, an AutoGeneratedField object is automatically created for each field in the data source. Each field is then displayed as a column in the GridView control in the order that the fields appear in the data source. This option provides a convenient way to display every field in the data source; however, you have limited control of how an automatically generated column field is displayed or behaves.

NoteNote

Automatically generated bound column fields are not added to the Columns collection.

Instead of letting the GridView control automatically generate the column fields, you can manually define the column fields by setting the AutoGenerateColumns property to false and then creating a custom Columns collection. In addition to bound column fields, you can also display a button column field, a check box column field, a command field, a hyperlink column field, an image field, or a column field based on your own custom-defined template. For more information, see Columns.

NoteNote

Explicitly declared column fields can be used in combination with automatically generated column fields. When both are used, explicitly declared column fields are rendered first, followed by the automatically generated column fields.

The following example demonstrates how to use the AutoGenerateColumns property to automatically create bound field columns in a GridView control for each field in the data source.
