[HttpPost]
public ActionResult Index([ModelBinder(typeof(DevExpressEditorsBinder))] IndexModel model)
{
var initialData = GenerateInitialData();
UpdateModel(initialData);
return View(initialData);
}
This controller throws an InvalidOperationException on the UpdateModel line when the view contains a DevExpress combobox. Do you know what is causing this?
I’m attaching a project to demonstrate to problem.
Thanks,
Aske
Hello Aske,
It is necessary to use the DevExpressEditorsBinder object instance as a default model binder to make our MVC editors accept values from the client side in a proper way. The UpdateModel method doesn't use the ModelBinder attribute of your action.
So, we can set the default binder in the Application_Start event handler in the Global.asax.cs file, for example.
Code protected void Application_Start()
{
ModelBinders.Binders.DefaultBinder = new DevExpressEditorsBinder();
...
}
