    Type: System.Boolean
    true to have the summary display model-level errors only, or false to have the summary display all errors.
  • message
    Type: System.String
    The message to display with the validation summary.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type HtmlHelper. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

The ValidationSummary method displays a list of all validation messages on the page.

If the DefaultModelBinder instance cannot bind a form-field value to the model, the binder adds an error to the ModelState object. When the view is rendered, the validation messages and validation summary are displayed based on the Errors property of the ModelState object.
