Udayaraju

Hi Dudes, Plz Solve these I am trying to implement a sample report in asp.net using crystal reports10.0. But i get an error of Object reference not set to an instance of an object Here's my code

public void btn_Click(object sender, EventArgs e)
{
frmPreview Preview = new frmPreview();
rptInformation Info = null;

        TableLogOnInfo logOnInfo = DBManager.getCrystalLogInfo(); //CorrectStatment
        Info = new rptInformation();

        Info.Database.Tables\[0\].ApplyLogOnInfo(logOnInfo); //Correct

        formulaFieldDefs = Info.DataDefinition.FormulaFields;

        formulaFieldDef = formulaFieldDefs\["CompanyName"\];
        formulaFieldDef.Text = "'" + Global.CompanyName + "'";

        Preview.crystalRptViewer.ReportSource = Info; //Error
         
    }

Here I placed CrystalReportViewer in frmPreview

It seems that you are doing this in Winforms... I think this is not the right section to post this. :mad: On this ... you didnt mentioned where exactly the error you are getting...?

I am trying to Implement in Asp.net itself. I tried in these way.. Is there any better approach I have specified the error Preview.crystalRptViewer.ReportSource = Info; //Error: Object reference is not set to an instance of an object

Did you bind the data source properly? Are you trying this in your Development environment or in Production server. Generally this sort of error comes when Crystal report is not found in the server. :confused:
