Bug: Grid throws NullReferenceException if Name is not specified

[Roger Lipscombe]

@(Html.Telerik().Grid(Model.Orders)
    .Columns(columns => { /* etc. */ })

causes the following stack trace:

[NullReferenceException: Object reference not set to an instance of an object.] Telerik.Web.Mvc.UI.ViewComponentBase.get_Id() +182 Telerik.Web.Mvc.UI.Grid`1.Prefix(String parameter) +58 Telerik.Web.Mvc.UI.GridBindingContextExtensions.GetGridParameter(IGridBindingContext context, String key) +55 Telerik.Web.Mvc.UI.GridDataProcessor.get_GroupDescriptors() +75 Telerik.Web.Mvc.UI.GridDataProcessor.EnsureDataSourceIsProcessed() +133 Telerik.Web.Mvc.UI.GridDataProcessor.get_ProcessedDataSource() +29 Telerik.Web.Mvc.UI.Grid`1.CreateRenderingData() +381 Telerik.Web.Mvc.UI.Grid`1.WriteHtml(HtmlTextWriter writer) +1237

It's caused by missing out the Name:

@(Html.Telerik().Grid(Model.Orders)
    .Name("Orders")
    .Columns(columns => {

The exception should be more user-friendly.

Thanks for your post, I just came across the same problem and found your solution to stop this Exception from happening. I agree, throwing a generic Null Reference exception for this is pretty annoying, and doesn't tell you at all what is causing it.
