Try with:
DataRow[] drows = dtBind.Select(string.Format("Doc_Id={0} AND DED_Id={1}", Doc_Id, row));
The fact is that Select method returns an array of
DataRow
objects. It means that the result of the select can be more than one.
You can easly that check if
drows.Count > 0
, ii means that he found something with that filter. Accessing the row is easy as
drows[x]
where x is a number of array element (which starts from 0).
