|---|
The function name should not include any parentheses or parameters. |
Set this property to the name of the function that performs the client-side validation.
Because the client validation function runs on the target browser, the function must be written using a scripting language supported by the browser, such as JScript or VBScript.
This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and ASP.NET Themes and Skins.
The following code example demonstrates how to use the ClientValidationFunction property to specify the name of the function that performs client-side validation. The validation function checks for even numbers. For a description of the function parameters, see the Remarks section of CustomValidator.

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. |
