I have added a property to a subclassed entity, the property is DaysLate and it has some internal calculations and null checks to determine how many days late an item is. However, when attempting to project this onto a DataView, I ran into an issue where there is no MyProjectItemFields (the base class is ProjectItemEntity). Is there a way to project my custom properties onto a DataView, or is there a better way to do this than projection?

Thanks,

Jeremiah

Is there any reason why you couldn't put this extra field in a user code region or in a partial class of the entity? This is how I usually handle calculated properties for entities.

Use an EntityProperty instance to project the property you added yourself.

So, essentially, I would want to do something like:

_propertyProjectors.Add (new EntityPropertyProjector (new EntityProperty ("DaysLate"), "DaysLate"));

And repeat that for any calculated fields that I want to include in the projection.

Hello, when you use

_propertyProjectors.Add (new EntityPropertyProjector (new EntityProperty ("DaysLate"), "DaysLate"));

, your dataview doesn't contains the field or you have a runtime exception? If there is a runtime exception, could you post the call stack?

I'm not receiving any errors, I just wanted to post a code sample so that I could be sure I was doing the right thing.

That was a correct code example.
