ValidationSummary.ShowSummary Property

Gets or sets a value indicating whether the validation summary is displayed inline.

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

public bool ShowSummary { get; set; }
/** @property */
public boolean get_ShowSummary ()

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

public function get ShowSummary () : boolean

public function set ShowSummary (value : boolean)

Not applicable.

Property Value

true if the validation summary is displayed inline; otherwise, false. The default is true.

This property can be used in addition to the ShowMessageBox property to control where the validation summary is displayed. If this property is set to true, the validation summary is displayed on the Web page.

NoteNote:

If both the ShowMessageBox and ShowSummary properties are set to true, the validation summary is displayed in both a message box and on the Web page.

The following code example demonstrates how to use the ShowMessageBox and ShowSummary properties to specify that the validation summary is displayed in both a message box and on the Web page.

Security noteSecurity Note:

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview (Visual Studio).
