Property Value

The input control to compare with the input control being validated. The default value is String.Empty.

Use the ControlToCompare property to specify an input control, such as a TextBox control, to compare with the input control being validated. If the input control specified by this property is not a control on the page, an exception is thrown.

NoteNote:

Do not set both the ControlToCompare and the ValueToCompare property at the same time. You can either compare the value of an input control to another input control, or to a constant value. If both properties are set, the ControlToCompare property takes precedence.

For more information, see BaseValidator.ControlToValidate.

NoteImportant:

  If the control to compare is hidden or is inside a container (such as a Panel control) that is not visible, the validator performs server-side validation only. The validator client script supports only visible controls.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and Introduction to ASP.NET Themes.

The following code example demonstrates how to use the ControlToCompare property to specify the control to compare with the control being validated.

Security noteSecurity Note:

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview (Visual Studio).
