Question

I m using MVC4. I need a combobox which will allow a user to input a new value if it does not exist, or which will automatically be selected if it exists among the available values.
How can I achieve this ?

@Html.DropDownListFor(Function(model) model.XYZ.Id, 
                      New SelectList(Model.XYZ, 
                                     "ID", 
                                     "Name", 
                                     Model.XYZList.First().Id))

This will generate a dropdownlist , but it won’t allow users to type a new entry.
Thanks

HTML does not have combobox like in windows forms. You should try javascript. Check out jquery autocomplete.
