    I've got a ComboBox which uses Grouping and I'm having trouble setting the selected item:

                      .HtmlAttributes(new { style = "width:100%;" })
                      .DataSource(source => source
                          .Group(g => g.Add("GroupKey", typeof(string)))
                          .Transport(transport => transport
                              .Read(read =>
                                  read.Action("GetMyItems", "MyController");

    My controler is returning JSON in the following format with one of the items optionally having "Selected":true

    [{"GroupKey":"Address","GroupName":"Address","Selected":false,"Text":"Correspondence Post Code","Value":"821"},...etc..]

    Hello Kevin,

    The ComboBox will not pre-select an item that has a property Selected set to "true". Selecting an item can be done either by specified either by using the SelectedIndex() method (calling it with the index of the item you want to be selected, for example: SelectedIndex(3)) or by using the Value() method, to which you can pass the text of the item you want to select, for instance: Value("Item1").
