Custom Validation Method Async

[Erik]

Hi,

I need an example on how to use an ajax async request inside an "addMethod" call from the grid component.

$.validator.addMethod("myFunction", function (value, element, params) {

            $.ajax({

                type: "GET",

                url: 'MyFunction',

                ...

                },

                success: function (data) {

                   return 

                }

            });

        }, "Error"); 

    });

With this code, the validator returns false before the ajax request completes. I did it this way instead of using the "remote" ValidationRule because I need to pass two parameters to the function on the server. If there is a better solution to this, please let me know.

Thank you.

Hi Erik 

Thanks for contacting Syncfusion Support. 

Query:-  I did it this way instead of using the "remote" ValidationRule because I need to pass two parameters to the function on the server. If there is a better solution to this, please let me know. 

 

We have checked your query and we have already discussed in our syncfusion knowledge base  about how to perform serverside validation on server side. From this you can pass the required values to serverend through ajax post and perform validation on it.  

 

For your convenience, refer to the KB link:-
