Hi,

i use the RadPropertyGrid to show the properties of an ExpandoObject in unbound mode (AutoGenerateBindingPaths=false and AutoGeneratePropertyDefinitions=false). The PropertyDefinitions are created in code by my ViewModel.

In pseudo code my view model looks like:

dynamic model = new ExpandoObject();
model.MyProperty = 42;
 
PropertyDefinition property = new PropertyDefinition
{
     DisplayName = "MyProperty",
    Binding = new Binding("MyProperty")
    {
        Source = model,
        Mode = BindingMode.TwoWay
    }
};

On a first glance it seems to work. The property with the current value appears in the PropertyGrid.
But unfortunally the update is not working. When I change the value of the property in the PropertyGrid, the model is not updated. 

Is there a mistake on my side?


Best regards,
Thomas

The "Visionaries" 2014 may forgot about bugs from good old 2012. Surprise...they are still alive.
