ValidationSummary Styles and Templates

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Default Style and Template

The following shows the XML namespace mappings that you have to specify when you work with styles and templates.

<!-- XML Namespace mappings. -->
xmlns:ctl="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data.Input"
xmlns:sys="clr-namespace:System;assembly=mscorlib"
xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows">
Important noteImportant Note:

The default templates for controls in Silverlight 4 still use the Silverlight 3-style prefixes, such as controls: and data: instead of sdk:. This is because the default control templates support Silverlight 3 and Silverlight 4 simultaneously. For more information, see Prefixes and Mappings for Silverlight Libraries.

NoteNote:

The default templates still specify the vsm: XML namespace mapping for the VisualStateManager element for legacy reasons. You can however, use the VisualStateManager element without specifying the vsm: mapping.

The following XAML shows the default style and template for the ValidationSummary control.
