as you can see in the attached first clip, my app throw an exception when I move the cursor outside the new row (only for ComboBox column), and it crash if I try to create a new row, as you can see in.
In both cases the grid is deserialized on "form load" event, with this options:
private static DeserializationOptions Deseralization()
deserializationOptions.DeserializeColumns = true;
deserializationOptions.DeserializeFiltering = true;
deserializationOptions.DeserializeGrouping = true;
deserializationOptions.DeserializeGroupSummaries = true;
deserializationOptions.DeserializeSorting = true;
deserializationOptions.DeserializeStyle = false;
In debug I can't intercept and manage any of this exceptions, because are internal to yours libraries.
It's very important and urgent to resolve these problems.
