custom grid validation with $http.get

[Wit]

My validation rule has to make a call to server. I have tried to add $http.get as part of myRule function but is not working.

Please see example code:

Thank you

Hello Wit,

I would recommend using a synchronous request to ensure that the response is received before the validation function has finished executing. For example: 

function (input){
    var valid = true;
    if (input.is("[name='ProductName']") && input.val() != "") {
        $.ajax({
            type: "GET",
            url: "someurl",
            async: false
        })
         .success(function(data){
            if(!data.someCondition){
                valid = false;
            }
        });
    }
    return valid;
}
