  1. Dear Arun Potti,

    Thank you for the example. It worked perfectly.

    I am however, stuck at a point where I cannot cancel a Form save event within my REST call. It works fine when executed outside the REST call.

    Here is my code snippet:

    function TSOCheckForProducts(ExecutionObj) {
    var Products = 0;
    var opportunityid = Xrm.Page.data.entity.getId();
    SDK.REST.retrieveMultipleRecords(
    “OpportunityProduct”,
    “$select=PricePerUnit&$filter=OpportunityId/Id eq (guid'” + opportunityid + “‘) and (new_ProductService eq false)”,
    function (results) {
    Products = results.length;
    },
    function (e) { //on error
    alert(e.message);
    },
    function () { //on Complete
    ExecutionObj.getEventArgs().preventDefault(); //This does NOT work
    }
    );

    ExecutionObj.getEventArgs().preventDefault(); //This works
    }

    Now, how do I prevent form close event??

    Thanks!

      • Hi Arun,

        Thank you for replying back.

        Consider the following example:
        I have form in CRM 2011 called ‘Contacts’.
        Now in this form, if a user enters data in some fields and then clicks on ‘Save & Close’, then I wish to cancel his form close event i e. prevent the user from saving and closing the form.

        For this I am using the following line of code:
        ExecutionObj.getEventArgs().preventDefault();

        Now, this code does not work when called inside the successCallback function of REST’s retrieveMultipleRecord().

        However, it works successfully when called outside the successCallback function.

        Now, How do I make that line of code work inside REST method??

      • Hi Harshit,
        Have you tried, creating a function with only this line ExecutionObj.getEventArgs().preventDefault();
        calling new function inside successcallback() ?
