public String[] getProposalNumbers()
{
db.openConnection();
String query = @"Select ProposalNo From Proposal";
SqlCommand command = new SqlCommand(query, DB.getConnection());
SqlDataAdapter da = new SqlDataAdapter(command);
DataTable dt = new DataTable();
da.Fill(dt);
int NoOfRows = dt.Rows.Count;
String[] proposalNo = new String[NoOfRows];
