PropertyEditors.Nullable - Possibility to enter 'null' value to a PropertyEditor which edits a nullable property (Nullable<>)

nullable type

Exists a editor that handle numeric nullable types, letting the user set its value to null? And then it will be useful for me to have such type of editor.
Now I use the following technique:
associate a WinStringPropertyEditor to a nullable decimal field.
Handle these events in a view controller:

        void _importoEdit_ParseEditValue(object sender, ConvertEditValueEventArgs e)
        {
            TextEdit _importoEdit = sender as TextEdit;
            if(e.Value.ToString() == string.Empty)
                e.Value = null;
            e.Handled = true;
        }

        void _importoEdit_FormatEditValue(object sender, ConvertEditValueEventArgs e)
        {
            if(e.Value != null)
            {
                if(e.Value.ToString() == string.Empty)
                    e.Value = null;
                else
                    e.Value = Convert.ToDecimal(e.Value).ToString("C");
            }
            e.Handled = true;
        }

Hi,

By default, the DevExpress.ExpressApp.Win.Editors.WinDecimalPropertyEditor is used to represent values of the decimal type. To force the editor to work with null values, you should set the Properties.AllowNullInput property value to true. Please refer to the editmask thread to learn how to properly access a property editor and change its properties.
