    hi,

    I am trying to use a combo box (also tried it in autocomple and it didn't work).
    I  took the code from your sample and it works fine in my test page (so links and scripts are ok), but when i try to change the address of the remote OData feed to my other project it does not show anything.
    If i just copy the address to IE9 - the service look fine and i got data.
    Any idea what i have done wrong? any tests i can do?

    Thanks

    Eli

    I am having the same problem with the same results , per the attached images. Are we able to explain why this is not working?
    Let me know if there is anything I can give you to help you diagnose the problem.

    Thanks

    I have some additional information for you. 
    I have one of your examples working and the only difference is the odata service url.
    Here is the not working example:

    IMPORTANT: I notice when this non-working one executes, the request is bad and it is using "http://wcf-clsearch.ryanhelms.com/ServerDataService.svc/Servers?$format=json&$inlinecount=allpages&$callback=callback" ,,,, something seems weird there.

    Request:     
    $("#Server").kendoComboBox({
        dataTextField: "CompanyName",
        dataValueField: "SupplierID",
        dataSource: {
            type: "odata",
            serverFiltering: true,
            transport: {
            }
        },
        change: function () { }
    }).data("kendoComboBox");

    OData Service Response:
    <?xml version="1.0" encoding="iso-8859-1" standalone="yes"?>
      <title type="text">Servers</title>

          </m:properties>
        </content>
      </entry>
    </feed>

    For spaces sake, I cut all of the results from above except the first one, as there were a few hundred in the resultset.

    Now, this next version works and populates the combobox.

    Request:
    $("#Server").kendoComboBox({
                dataTextField: "CompanyName",
                dataValueField: "SupplierID",
                dataSource: {
                    type: "odata",
                    serverFiltering: true,
                    transport: {
                        read: "http://services.odata.org/Northwind/Northwind.svc/Suppliers"
                    }
                },
                change: function () {}
            }).data("kendoComboBox");

    OData Service Response:
    <?xml version="1.0" encoding="iso-8859-1" standalone="yes"?>
      <title type="text">Suppliers</title>

          </m:properties>
        </content>
      </entry>
    </feed>

    Please explain the difference, since everything is exactly the same, except the fields in the results.

    Thanks

    Hello,

    The generated URL seems correct. Could you please verify that your service has the correct JSONP behavior. Check these links for more information:
