I got this:
DataTable dtEntity = CreateDataTable(); drEntity = dtEntity.NewRow();
Then I add data to the row (or not). Lots of code, real
AFAIK, there is no method that does this in the framework. Even if there was support for something like this in the framework, it would essentially be doing the same thing. And that would be looking at each cell in the DataRow to see if it is empty.
