Filter not working for Kendo Grid with Dynamic LINQ Helpers

[Umair]

So I was playing around with KendoUI and incorporated Dynamic LINQ Helpers in my ASP.NET MVC project. I followed the small tutorial here.
So far, the paging and sorting is working fine but the filtering is not working. Every time I try to filter my records, there is an exception on server side like the following
Operator '=' incompatible with operand types 'String' and 'String[]'
Can anyone help me with this?
Here is my Grid code (yes I am using Angular)

 

$scope.mainGridOptions = {
            dataSource: {
                transport: {
                    read: {
                        url: ConfigData.BaseUrl + "ChartOfAccounts/GetData",
                        type: 'post',
                        dataType: "json"
                    },
                    update: {
                        url: ConfigData.BaseUrl + "ChartOfAccounts/UpdateData",
                        type: "post",
                        dataType: 'json'
                    },
                    create: {
                        url: ConfigData.BaseUrl + "ChartOfAccounts/CreateData",
                        type: "post",
                        dataType: 'json'
                    },
                    destroy: {
                        url: ConfigData.BaseUrl + "ChartOfAccounts/DeleteData",
                        type: "post",
                        dataType: 'json'
                    }
                },
                serverPaging: true,
                serverFiltering: true,
                serverSorting: true,
                pageSize: 5,
                batch: true,
                schema: {
                    data: "Data",
                    total: "Total",
                    model: {
                        id: "ID",
                        fields: {
                            ID: { type: "number" },
                            AccountNumber: { type: "string" },
                            AccountName: { type: "string" }
                        }
                    }
                }

            },
            columns: [
                { field: "AccountNumber", title: "Account Number", width: "130px" },
                { field: "AccountName", title: "Account Name", width: "130px" }
            ]

        };

Here is the server side code

var chartofAccounts = DataStore.ChartOfAccounts.AsQueryable().ToDataSourceResult(request);
return Json(chartofAccounts, JsonRequestBehavior.DenyGet);

The DataStore is simple a static class containing static list of ChartOfAccounts

Hello,

Could you clarify which tutorial have you followed? The example that we have with dynamic linq and MVC posts the state as JSON in order to correctly deserialize the filters on the server.

I am not using MVC wrappers. I don't want to use MVC wrappers. I want to work with KendoUI and Angular. The Dynamic LINQ helpers are throwing exception when I filter the records. The example you provided doesn't help

Hello again,

The example that I linked does not use the MVC wrappers but the JavaScript initialization:

$(function () {
    $("#grid").kendoGrid({
        ...

The configuration when using angular will be the same.
