ComboBox Filter Not working when I use cascadeFrom

[Chang]

I am using a kendoComboBox to load the organization list, and I am not able to change the filter to use "contains". It always search by default using "startsWith".  
The Kendo document shows it is very easy and straightforward to use the filter, and to add filter: "contains", should do the magic for me. But I've tried many times and it didn't work. Can you help me out?
The difference in my example is that I use cascadeFrom, and I turn on serverFiltering.


    var organizationDropDown = $("#organization").kendoComboBox({
        autoBind: false,
        dataSource: new kendo.data.DataSource({
            serverFiltering: true,
            transport: {
                read: {
                    url: ATSDashboardWebAPI + "api/GetOrganizations",
                    data: GetOrgType,
                    dataType: "json"
                }
            },
            requestEnd: function(e) {
                orgsLoaded = true;
            }
        }),
        dataTextField: "OrganizationName",
        dataValueField: "OrganizationId",
        value: SetDefaultOrganization(),
        //filter: { field: "OrganizationName", operator: "contains", value: this["#text"] },
        filter: "contains",
        cascadeFrom: "orgtype"
    }).data("kendoComboBox");

Hello Chang,

This demo page uses cascadeFrom together with filter: "contains" and everything seems to work as expected.
You have turned on serverFiltering which means that the DataSource will expect the server to return the filtered data (e.g. data filtering happens on the server). Could you please confirm that the server implementation filters data by a "contains" rule?

How do I implement the "contains" on the server side? There is a API call that takes input of OrganizationType and returns a list of organizations. It is using a json object and we do not have any parameter supporting for sorting in this json object. Is this the problem you pointed out?

 transport: {
                read: {
                    url: ATSDashboardWebAPI + "api/GetOrganizations",
                    data: GetOrgType,
                    dataType: "json"
                }

Hi,

I attached a sample project that demonstrates using contains filter on the server in the described scenario.
