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

public virtual string DataTextField { get; set; }
/** @property */
public String get_DataTextField ()

/** @property */
public void set_DataTextField (String value)

public function get DataTextField () : String

public function set DataTextField (value : String)

Not applicable.

Property Value

The field name to bind to the ButtonColumn. The default is an empty string ("").

Use the DataTextField property to specify the field name from the data source to bind to the Text property of the buttons in the ButtonColumn object.

Binding the column to a field instead of directly setting the Text property allows you to display different captions for the buttons in the ButtonColumn by using the values in the specified field.

The value of this property is stored in view state.

The following code example demonstrates how to use the DataTextField property to bind the ButtonColumn object to a field in a data source.
