C# and Crystal Reports


  • My Object is to call Crystal Reports XI class library including crystal Reports viewer.

    What I did:

    I create a class library with a window form and added crystal reports viewer. The following code is used.

    [code under the window form]

    public long init(object ReportObject, string strTitle, bool isMaximized)


                Cursor.Current = Cursors.WaitCursor;

                this.Text = strTitle;


                this.crystalReportViewer1.ReportSource = ReportObject;            



                if (isMaximized == true )


                    this.WindowState = FormWindowState.Maximized;





                Cursor.Current = Cursors.Default;       

                return (1);          




    [code under the .cs file]

    public void ShowReport(ref object ReportObject, string strTitle, bool isMaximized)


    Crystal_Report_Viewer.Net.Report_Viewer Obj = new Crystal_Report_Viewer.Net.Report_Viewer();           


                Obj.init(ReportObject, strTitle, isMaximized);



    This code seems to be ok but when I call a method ShowReport() from third party application, a meessage get appeard : invalid Report Source, can any expert help me out to resolve this issue. The following code I used in third party application after regersting assembly.

    Obj = new CrystalViewer.Crystal();


    What should I do?

  • Hello,

    I recommend you to consult the third-party vendor of the method that you are using for some better support.
