Property Value

Type: System.String
The header text displayed at the top of the summary. The default is String.Empty.

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 following code example demonstrates how to use the HeaderText property to display a title for the ValidationSummary control.
