Question

I want to use upshot remoteDataSource to get data. Parameters are exceeding limit so I used  [Query(HasSideEffects=true)] so I can use post method on RIA service. 

now I want to call same method using upshot remoteDataSource ....but it fails. Its calling method using 'GET' . is there any way to to use 'POST' ?

you may add the data to a hidden element and submit and access it the data using post method

Hi,

For what I have seen, this is nog possible. Retrieving data is done by the default type of an AJAX request and that is GET. What you can try is the following:

1. In the upshot.js file, look for the DataProvider.ria.js
2. In that part go to the var instance members and look for the get method
3. In there you have an ajax call: change this so it uses the type: "POST"

$.ajax({
    url: upshot.DataProvider.normalizeUrl(parameters.url) + "json/" + operation,
    data: $.extend({}, transformParameters(operationParameters), transformQuery(queryParameters || {})),
    success: success && function () {
         arguments[0] = getQueryResult(arguments[0]);
         success.apply(self, arguments);
    },
    error: error && function (jqXHR, statusText, errorText) {
         error.call(self, jqXHR.status, self._parseErrorText(jqXHR.responseText) || errorText, jqXHR);
    },
    dataType: "json",
    type: "POST"
});

Try this, I don't know if it will work, but it think it will. Ofcourse don't forget to add an attribute on the function you call in the service.
