I'm using a datareader to get data from an sql table. The line that gives the
error is as follow,
dtrReceivers["Site_V"].ToString()
which gives the error,
Invalid attempt to read when no data is present
which is correct. The line works when data is in the row. But shouldn't the
data reader return a null! How can I check to see if data is in the row?
Thanks in advance,
David
