I have a string custom property in a BO which I bind to a MicroFour.StrataFrame.UI.Windows.Forms.DevEx.TextEdit.

When setting the value of the property at run-time, with code 

Customer.CustomProperty = "SomeValue";

the control does not show the changed value. Is it something I'm not doing right? BindingUpdateMode and ControlSourceUpdateMode are both OnPropertyChanged.

I have tried this with your DevEx sample application, and does not work there either.
