TwoWay-Binding with ExpandoObject

[IT-Support]

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
