Remarks

Use this property to display a title for the ValidationSummary control.

The HeaderText property is not HTML encoded. Therefore, HTML tags can be included in HeaderText.

The value of this property, when set, can be saved automatically to a resource file by using a designer tool. For more information, see LocalizableAttribute and ASP.NET Globalization and Localization.
