I was unable to apply the above suggestions to my problem. I have managed to populate the report with
the data i need to by creating a dataset on the fly. The only problem is if i try to print the report or move to the next page the report viewer is prompting the user for security credentials for the database.

I have attached the code behind for my print report button.

 protected void ButtonReport_Click(object sender, EventArgs e)
        {
 
// Create Connection
SqlConnection myConnection;
myConnection = new SqlConnection(ConnString);
 
// Create Dataset Object
DataSet dsCustomers = new DataSet();
 
// Populate Sql String Variable
String SqlString = DropDownList1.Text.Trim();  
 
// Create Data Adapter
SqlDataAdapter daCustomers = new SqlDataAdapter(SqlString, myConnection);
 
// Fill Dataset
daCustomers.Fill(dsCustomers, "Customer_WithStaffAndPostCodeArea");
 
//create the report document
doc = new ReportDocument();
 
string fileName = Server.MapPath("~/Reports/MyReport.rpt");
 
//load the rpt file to document
doc.Load(fileName);          
 
doc.SetDataSource(dsCustomers);
 
CrystalReportViewer1.BestFitPage = false;
CrystalReportViewer1.Width = new Unit("740px");
CrystalReportViewer1.Height = new Unit("1000px"); 
 
 
CrystalReportViewer1.ReportSource = doc;
 
        }
