I am generating a report into a dataGridView component and want to print it out. I found an article on this site that had a DataGridViewTestApplication which I downloaded and compiled. The application worked well. I copied and pasted the functions into my application which also had a dataGridView1 conponent on the form. The code follows:
private void view_all()
{
Cursor.Current = Cursors.WaitCursor;
SqlConnection sqlConnection = null;
SqlCommand sqlCommand = null;
SqlDataReader sqlReader = null;
try
{
string strQuery = "SELECT Name, Telephony, RtGide, Code, Acct, AirDir FROM APRL.dbo.Patchdata where Code like 'b%'";
string datasource = "Dave-HP\\SQLEXPRESS";
SqlConnectionStringBuilder bu = new SqlConnectionStringBuilder();
bu.DataSource = @datasource;
bu.IntegratedSecurity = false;
bu.UserID = "Dave";
bu.Password = "FunFern";
MSQLcon.ConnectionString = bu.ConnectionString;
MSQLcon.Open();
sqlCommand = new SqlCommand(strQuery, MSQLcon);
sqlReader = sqlCommand.ExecuteReader();
while (sqlReader.Read())
{
object[] row = { sqlReader[0], sqlReader[1], sqlReader[2], sqlReader[3], sqlReader[4], sqlReader[5] };
dataGridView1.Rows.Add(row);
}
}
catch (Exception exc)
{
MessageBox.Show(exc.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
return;
}
finally
{
Cursor.Current = Cursors.Default;
MSQLcon.Close();
if (sqlReader != null)
{
sqlReader.Dispose();
sqlReader = null;
}
if (sqlCommand != null)
{
sqlCommand.Dispose();
sqlCommand = null;
}
}
}

The viewall function fills the dataGridView with the proper data and this works fine. The void aVSRoutingGdToolStripMenuItem_Click functions is called from a menu option and first calls the viewall function to populate the data grid. From there on the code is right from the test program which works. However all I get are blank pages. I have a printDocument1 on my form. I think the printDocument does not know where to get the data from but I can't find out how to make this happen. Any help would be greatly appreciated.
Thanks!
