To reproduce: 1. Add a RadRibbonBar with one tab and a RadRibbonBarButtonGroup. 2. Add a RadDropDownListElement in the RadRibbonBarButtonGroup and use the following code snippet: DataTable dt = new DataTable(); Student student = new Student(123, "John Peterson", "B"); public Form1() { InitializeComponent(); this.radLabel1.Text = "Student's Id: " + student.Id.ToString(); dt.Columns.Add("Id"); dt.Columns.Add("Name"); dt.Rows.Add(1, "Student1"); dt.Rows.Add(2, "Student2"); dt.Rows.Add(3, "Student3"); student.PropertyChanged += student_PropertyChanged; this.radDropDownListElement1.BindingContext = new BindingContext(); this.radDropDownListElement1.DataSource = dt; this.radDropDownListElement1.DisplayMember = "Name"; this.radDropDownListElement1.ValueMember = "Id"; this.radDropDownListElement1.DataBindings.Add("SelectedValue", student, "Id", true, DataSourceUpdateMode.OnPropertyChanged); } private void student_PropertyChanged(object sender, PropertyChangedEventArgs e) { if (e.PropertyName == "Id") { this.radLabel1.Text = "Student's Id: " + student.Id.ToString(); } } public class Student : System.ComponentModel.INotifyPropertyChanged { int m_id; string m_name; string m_grade; public event PropertyChangedEventHandler PropertyChanged; public Student(int m_id, string m_name, string m_grade) { this.m_id = m_id; this.m_name = m_name; this.m_grade = m_grade; } public int Id { get { return m_id; } set { if (this.m_id != value) { this.m_id = value; OnPropertyChanged("Id"); } } } public string Name { get { return m_name; } set { if (this.m_name != value) { this.m_name = value; OnPropertyChanged("Name"); } } } public string Grade { get { return m_grade; } set { if (this.m_grade != value) { this.m_grade = value; OnPropertyChanged("Grade"); } } } protected virtual void OnPropertyChanged(string propertyName) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } } 3. If you change the selection in RadDropDownListElement you will notice that the Student.Id property is not affected. Note: this scenario works correctly with RadDropDownList control! Workaround: use a RadHostItem and use RadDropDownList: RadDropDownList ddl = new RadDropDownList(); ddl.MinimumSize = new System.Drawing.Size(100, 20); RadHostItem host = new RadHostItem(ddl); host.MinSize = new Size(100, 20); this.radRibbonBarButtonGroup1.Items.Add(host); ddl.DataSource = dt; ddl.DisplayMember = "Name"; ddl.ValueMember = "Id"; ddl.DataBindings.Add("SelectedValue", student, "Id", true, DataSourceUpdateMode.OnPropertyChanged);
