Displays a summary of all validation errors inline on a Web page, in a message box, or both.
Assembly: System.Web (in System.Web.dll)
[AspNetHostingPermissionAttribute(SecurityAction::LinkDemand, Level = AspNetHostingPermissionLevel::Minimal)] [AspNetHostingPermissionAttribute(SecurityAction::InheritanceDemand, Level = AspNetHostingPermissionLevel::Minimal)] public ref class ValidationSummary : public WebControl
<asp:ValidationSummary />
The ValidationSummary class is used to summarize the error messages from all validators on a Web page in a single location. You can summarize the error messages from a group of validators on a Web page by assigning the ValidationSummary control to a validation group by setting the ValidationGroup property.
The summary can be displayed as a list, as a bulleted list, or as a single paragraph, based on the DisplayMode property.
The summary can be displayed on the Web page and in a message box by setting the ShowSummary and ShowMessageBox properties, respectively.

When you use the ValidationSummary control inside an UpdatePanel control, make sure that the validator control and the control it is associated with are in the same panel. For more information about using the UpdatePanel control for partial-page updates, see Partial-Page Rendering Overview. |
For a list of initial property values for an instance of ValidationSummary, see the ValidationSummary constructor.
The following code example demonstrates how to use a ValidationSummary control to summarize the error messages from all validation controls on a Web page and display them in a bulleted list.
