Property Value
The name of the custom client script function used for validation. The default value is String.Empty, which indicates that this property is not set. Note: |
|---|
| 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 Introduction to ASP.NET Themes.
