Crystal Report with parameter problem -Pls help

[Kapil Shah via DotNetMonster.com]

Hello everybody,
I am trying to create a web application to generate Crystal Report with
Parameters. However I noticed that
ReportDocument. Load is used twice when the parameter page is loaded .
1) The first time ReportDocument. Load is used when the Crystal Report is
loaded and the parameter page is created.
2) The second time the ReportDocument. Load is again used when the user
enters the parameters in the parameters page.
My problem is I do not want the ReportDocument. Load to be used twice along
with the Parameter table . Would be greatful if anyone can help me with any
solution. The code is written below.. I have also used the post back method
but gives an error that object Report document not instantiated.


private void Page_Load(objec t sender,System.E ventArgs e)
{
(if(!Page.IsPos tBack)

string reportname= "C:\ReportWithP arameter.rpt"
LoadReportName( reportname)
)

}
private void LoadReport(stri ng reportName)

{
crDoc=new CrystalDecision s.CrystalReport s.Engine.Report Document();
crDoc.Load(repo rtName);

CrystalDecision s.CrystalReport s.Engine.Parame terFieldDefinit ions
crParamFieldDef initions = crDoc.DataDefin ition.Parameter Fields;
// create the table to hold the controls
Table table = new Table();
table.Width = 300;
table.BorderWid th=1;
table.BackColor = Color.LightGray ;
table.BorderCol or = Color.Gray;
table.CellSpaci ng = 10;
// table.GridLines = GridLines.Horiz ontal;
string paramName;

TableRow summaryRow = new TableRow();
TableCell summaryCell = new TableCell();
ParamTable.Rows[0].Cells[0].Controls.Add(t able);

Session["Report"] = crDoc;
}

}
Pls guide...

Hi Kapil,

From your code, I can't find ReportDocument load twice.
Could you give more info?
