Grid doesn't work MVC 4 RC

[peter]

Hi,
 I tried to move from MVC 3  to mvc 4. unfortunately, the following code is working properly on mvc 3, but on mvc4 rc shows "No records to display". how to avoid this issue?

@(Html.Kendo().Grid<Object>()    
    .Name("GridTest") 
    .DataSource(dataSource => dataSource
        .Ajax()
        .Read(read => read.Action("Test_Read", "Home"))
     )
     .Resizable(resize => resize.Columns(true))
     .Reorderable(reorder => reorder.Columns(true))

Thanks,

peter

I had the same problem.

Here is my solution:

1. disable proxy generation for the read function only
     

context.Configuration.ProxyCreationEnabled = false;

2. configure JsonFormatter like this (global.asax; application_start)

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.PreserveReferencesHandling = PreserveReferencesHandling.Objects;

3. set JsonRequestBehavior for the jsonresult in the read function to AllowGet

return Json(result, JsonRequestBehavior.AllowGet);

ends up like this:

public JsonResult Read([DataSourceRequest]DataSourceRequest request)

{

    var context = new SampleContext();

    context.Configuration.ProxyCreationEnabled = false;

    var data = context.Data;

    DataSourceResult result = data.ToDataSourceResult(request);

    return Json(result, JsonRequestBehavior.AllowGet);

}
