## Class TCustomValidator

Description

TCustomValidator class

TCustomValidator performs user-defined validation (either server-side or client-side or both) on an input component.

To create a server-side validation function, provide a handler for the OnServerValidate event that performs the validation. The data string of the input control to validate can be accessed by TServerValidateEventParameter::getValue of the event parameter. The result of the validation should be stored in the TServerValidateEventParameter::getIsValid property of the event parameter.

To create a client-side validation function, add the client-side validation javascript function to the page template. The function should have the following signature:

     <script type="text/javascript"><!--
     function ValidationFunctionName(sender, parameter)
     {
        // if(parameter == ...)
        //    return true;
        // else
        //    return false;
     }
     --></script>

Use the ClientValidationFunction property to specify the name of the client-side validation script function associated with the TCustomValidator.

Method Summary
boolean evaluateIsValid ()
array getClientScriptOptions ()
string getClientValidationFunction ()
boolean onServerValidate (string $value)
void setClientValidationFunction (string $value)
Methods
evaluateIsValid (line 79)

This method overrides the parent's implementation.

The validation succeeds if onServerValidate returns true.

- return: whether the validation succeeds
- access: public

boolean evaluateIsValid ()

Redefinition of:

TBaseValidator::evaluateIsValid()
  This is the major method for validation.

getClientScriptOptions (line 106)

Returns an array of javascript validator options.

- return: javascript validator options.
- access: protected

array getClientScriptOptions ()

Redefinition of:

TBaseValidator::getClientScriptOptions()
  Returns an array of javascript validator options.

getClientValidationFunction (line 60)

- return: the name of the custom client-side script function used for validation.
- access: public

string getClientValidationFunction ()
onServerValidate (line 94)

This method is invoked when the server side validation happens.

It will raise the OnServerValidate event. The method also allows derived classes to handle the event without attaching a delegate. Note The derived classes should call parent implementation to ensure the OnServerValidate event is raised.

- return: whether the value is valid
- access: public

boolean onServerValidate (string $value)

- string $value: the value to be validated

setClientValidationFunction (line 69)

Sets the name of the custom client-side script function used for validation.

- access: public

void setClientValidationFunction (string $value)

- string $value: the script function name
