Question

I have JS code something like shown below:

function ValidateBid(source, args) {
            var txtValue = $('#txtBid').val();
            $.ajax({ 
                type: "POST", 
                async: true,
                url: "BidDetail.aspx/ValidateValue", 
                contentType: "application/json; charset=utf-8",
                data: "{value:" + JSON.stringify(txtValue) + "}", 
                dataType: "json",
                success: function (msg) {
                    var resultAsJson = msg.d // your return result is JS array
                    args.IsValid = msg.d;

                    // Now you can loop over the array to get each object
                }
            });
            return args.IsValid;
        }

Here what happens is, it returns args.IsValid first and then it goes into the method args.IsValid. I have used CustomValidator and i am calling this function on its ClientValidationFunction.

What i want is, i want to return true or false on the basis of what Json Function ValidateValue returns.

The request is async so it will return value before it is set. So I think if you change async:false will work.
