<script type="text/javascript">
    var products = [
        "HD Video Player",
        "SuperHD Video Player",
        "SuperPlasma 50"
    ].map(function (val) { return { value: val, displayValue: val }; });

    function customParameterLookUpSource(s, e) {
        if (e.parameter.name == "parameter1") {
            e.dataSource = "/Home/GetData";
        };
        if (e.parameter.name == "parameter2") {
            e.dataSource = "https://jsonplaceholder.typicode.com/users";
        };
        if (e.parameter.name == "parameter3") {
            e.dataSource = products;
        }  
    }

    function customizeParameterEditors(s, e) {
        if (e.parameter.name == "parameter2") {
            e.info.editor = $.extend({}, e.info.editor);
            e.info.editor.extendedOptions = $.extend(e.info.editor.extendedOptions || {}, {
                valueExpr: 'username',
                displayExpr: 'name'
            });
        }
    }
