BindingSource.AddingNew is never called when I leave the cell of my datagrid. The DataGrid has as datasource the BindingSource which again has a "List" of "Customer". What does the BindingSource need to create a new Customer object and add it to the underlying ICustomerList ? Of course a interface has no constructor... but my customer object has a default constructor! Thats the Exception I get: <pre><code>System.MissingMethodException: The constcructor for the type "SAT.EnCoDe.Administration.ICustomer" was not found. </code></pre> bei System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) bei System.SecurityUtils.SecureCreateInstance(Type type, Object[] args) bei System.ComponentModel.BindingList<code>1.AddNewCore() bei System.ComponentModel.BindingList</code>1.System.ComponentModel.IBindingList.AddNew() bei System.Windows.Forms.BindingSource.AddNew() bei System.Windows.Forms.CurrencyManager.AddNew() bei DevExpress.Data.CurrencyDataController.OnCurrencyManagerAddNew() bei DevExpress.Data.CurrencyDataController.AddNewRow() bei DevExpress.XtraGrid.Views.Grid.GridView.OnActiveEditor_ValueModified(Object sender, EventArgs e) bei DevExpress.XtraEditors.Repository.RepositoryItem.RaiseModified(EventArgs e) bei DevExpress.XtraEditors.BaseEdit.OnEditValueChanging(ChangingEventArgs e) bei DevExpress.XtraEditors.TextEdit.OnMaskBox_ValueChanged(Object sender, EventArgs e) bei DevExpress.XtraEditors.Mask.MaskBox.RaiseEditTextChanged() bei System.Windows.Forms.TextBoxBase.WmReflectCommand(Message& m) bei DevExpress.XtraEditors.Mask.MaskBox.BaseWndProc(Message& m) bei DevExpress.XtraEditors.Mask.MaskBox.WndProc(Message& m) bei DevExpress.XtraEditors.TextBoxMaskBox.WndProc(Message& msg) bei System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) bei System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
