Hi

We are getting the error "No parameterless constructor defined for this object" when we try to bind collection to the Kendo grid and obviously the business objects that we have in our business layer has private constructors and it worked fine with Telerik.

Here is the stack trace of the error

Line 171:    {

Line 172:        //@(Html.Kendo().Grid<City.Australia.Framework.BL.UserInfo>()

Line 173:        @(Html.Kendo().Grid(Model.Users)

Line 174:            .Name("UserGrid")

Line 175:            .EnableCustomBinding(true)

Source File: d:\Development\City.Australia.Admin\City.Australia.Admin\Views\User\Search.cshtml Line: 173
