Hi I've been testing the ASP MVC and didnt find a way to use the grid edit inline with a field with dropdown list. is this possible? Even on the samples provided i've adapted the sample "Editing_Custom" to be Inline edit and get the same error which is "Uncaught ReferenceError: Employee is not defined "

Sorry, didnt mentioned initially, but the goal is to use the Inline edit, and i get the error when a new row is added to the grid. 

Thanks in advance. 
Congrats for your products.

Hi Ricardo,

 
You are getting this error because the Employee property of the model to which is bind the DropDownList is object. When you create new record Employee field pointer is set to null.  When the DropDownList is initialized and is bound to not-existing property the exception is thrown. To be able to create records in current scenario you should define default value for the Employee field in the following way:

Grid configuration:

.DataSource(dataSource => dataSource
    .Ajax()
    .Batch(true)
    .ServerOperation(false)
    .Events(events => events.Error("error_handler"))
    .Model(model =>
    {
        model.Id(p => p.OrderID);
        model.Field(p => p.OrderID).Editable(false);
        model.Field(p => p.Employee).DefaultValue(new Kendo.Mvc.Examples.Models.ClientEmployeeViewModel());
    })
    .Create(create => create.Action("EditingCustom_Create", "Grid"))
    .Read(read => read.Action("EditingCustom_Read", "Grid"))
    .Update(update => update.Action("EditingCustom_Update", "Grid"))
)

Also I would suggest to define OptionLabel in the ClientEmployee custom editor as follows:
@(Html.Kendo().DropDownList()
        .Name("Employee")
        .DataValueField("EmployeeID")
        .DataTextField("EmployeeName")
        .OptionLabel("Select employee")
        .BindTo((System.Collections.IEnumerable)ViewData["employees"])
)
