DVLocal is a Dataview, so the easier way to find out is to use Google: Google "DataView.Count"[^] - the first hit is a link to MSDN: MSDN: "DataView.Count Property"[^] which tells you all about it.

What is says is that it returns "the number of records in the DataView after RowFilter and RowStateFilter have been applied."

So the line:

C#

if (DVLocal.Count > 0)

will be true if there are any rows in the view, so at least one line to process.
