                                ValueField="id"   ForceSelection="true" Margin="2" TriggerAction="All" SelectOnFocus="true" EmptyText="Select a Class">
                               
                               
                            </ext:ComboBox>

in my controller i have written this function

/Data/getAll

public StoreResult getAll() 
        {
            List<ClassBL> list;

          list = DB.GetAll();
            return new StoreResult(list , list .Count );
        }

anybody guides me what is the right and best way to load combo box in asp.net MVC3?

Hi,

You should not set up QueryMode="Local" if you need to load a remote data. So, please remove it or set up to "Remote".
