CommandField.ShowCancelButton Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets a value indicating whether a Cancel button is displayed in a CommandField field.

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

public virtual bool ShowCancelButton { get; set; }
/** @property */
public boolean get_ShowCancelButton ()

/** @property */
public void set_ShowCancelButton (boolean value)

public function get ShowCancelButton () : boolean

public function set ShowCancelButton (value : boolean)

Property Value

true to display a Cancel button in a CommandField; otherwise, false. The default is true.

Use the ShowCancelButton property to specify whether the Cancel button is displayed in a CommandField object. A Cancel button can be displayed in a CommandField field when the corresponding record in a data-bound control is in edit or insert mode. The Cancel button allows the user to cancel the edit or insert operation and returns the record to its normal display mode.

When the ButtonType property of a CommandField field is set to ButtonType.Button or ButtonType.Link, use the CancelText property to specify the text to display for a Cancel button. Alternatively, you can display an image by first setting the ButtonType property to ButtonType.Image and then setting the CancelImageUrl property.

The following code example demonstrates how to use the ShowCancelButton property to hide the Cancel button displayed when a row in a GridView control is in edit mode.
