I have some Crystal Reports that were created using Crystal (external to Visual Studio) and are now loaded in the VS project. Before the report is previewed I set up the rep

    put your coding to load event while bind report don't put ispostback=false condition

    example

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim dt As New dsPrintRevisionStatus
        Try
            lblHeader.Text = Request.QueryString("name")
            If lblHeader.Text = "Report- Print Revision Status" Then
                Dim rpt As New rpt_PrintRevisionStatus
                rpt.SetDataSource(sqlHandler.ExecuteDataTable("SELECT * FROM [Print Revision Status]"))
                crtViewer.ReportSource = rpt
                crtViewer.DataBind()
    
            End If
        Catch ex As Exception
            lblError.Text = ex.Message
        End Try
    End Sub

    Use EnableDatabaseLogonPrompt to see the actual error

    Use Data Table instead of Data Set .. It works..

    If you have added the logon info as follows,

            LogInfo.ConnectionInfo.ServerName = "mcqueen";
            LogInfo.ConnectionInfo.Password = "abc123";
            LogInfo.ConnectionInfo.UserID = "sa";
            LogInfo.ConnectionInfo.DatabaseName = "tbboss";
    
            crysViewer.LogOnInfo.Add(LogInfo);
    

    simply put the crysViewer.LogOnInfo.Add(LogInfo); at the end of crystal Viewer parameter settings. Like follows.

        LogInfo.ConnectionInfo.ServerName = "mcqueen";
        LogInfo.ConnectionInfo.Password = "abc123";
        LogInfo.ConnectionInfo.UserID = "sa";
        LogInfo.ConnectionInfo.DatabaseName = "tbboss";
    
    
        int exportFormatFlags =(int)(CrystalDecisions.Shared.ViewerExportFormats.PdfFormat | CrystalDecisions.Shared.ViewerExportFormats.ExcelFormat);
        crysViewer.AllowedExportFormats = exportFormatFlags;
        crysViewer.ReportSource = Server.MapPath("Reports/Report1.rpt");
        crysViewer.ParameterFieldInfo = paramFields;
    
        crysViewer.LogOnInfo.Add(LogInfo);

    I had same problem but I found a simple solution. i.e. just replace dataset with the data table and it will work fine.

    I have found the best way to fix a bug is to post the question to StackOverflow and 5 minutes later work it out yourself. Needless to say, I worked this out.

    As well as setting all the log on info in the report objects, I also have to do it in the Crystal Viewer component in ASP.NET. So I just write some code like this and it all works, no prompts.

    <CR:CrystalReportViewer Height="500px" ID="Viewer" runat="server" />
    
    var connectionInfo = new ConnectionInfo();
        connectionInfo.ServerName = "192.168.x.xxx";
        connectionInfo.DatabaseName = "xxxx";
        connectionInfo.Password = "xxxx";
        connectionInfo.UserID = "xxxx";
        connectionInfo.Type = ConnectionInfoType.SQL;
        connectionInfo.IntegratedSecurity = false;
    
    for (int i = 0; i < Viewer.LogOnInfo.Count; i++)
    {
        Viewer.LogOnInfo[i].ConnectionInfo = connectionInfo;
    }
