Hi victimized dude,
Here I've a solution for your problem hope it will be useful.
All you need to care about is passing the parameter to the report via the ParameterField in CrystalReport.
Have a look to the code below

//This is the name of the Crystal report
AgentLicenceCardCollectively1 report = new AgentLicenceCardCollectively1();
ParameterFields myParams = new ParameterFields();
ParameterField paramOfficerName = new ParameterField();
ParameterField paramOfficerPost = new ParameterField();
ParameterField paramCompanyId = new ParameterField();
ParameterField paramALICO = new ParameterField();

ParameterDiscreteValue myDiscreteValue1 = new ParameterDiscreteValue();
ParameterDiscreteValue myDiscreteValue2 = new ParameterDiscreteValue();
ParameterDiscreteValue myDiscreteValue3 = new ParameterDiscreteValue();
ParameterDiscreteValue myDiscreteValue4 = new ParameterDiscreteValue();

// Set the ParameterFieldName to the name of the parameter
// created in the Field Explore
paramOfficerName.ParameterFieldName = "officerName";
paramOfficerPost.ParameterFieldName = "officerPost";
paramCompanyId.ParameterFieldName = "companyId";
paramALICO.ParameterFieldName = "ALICO";
myDiscreteValue1.Value = cboOfficerName.Text;
paramOfficerName.CurrentValues.Add(myDiscreteValue1);
myDiscreteValue2.Value = cboPost.Text;
paramOfficerPost.CurrentValues.Add(myDiscreteValue2);
myDiscreteValue3.Value = cboCompanyName.Text.Substring(0, 2);
paramCompanyId.CurrentValues.Add(myDiscreteValue3);
myDiscreteValue4.Value = "";

// Add param object to params collection
myParams.Add(paramOfficerName);
myParams.Add(paramOfficerPost);
myParams.Add(paramCompanyId);
myParams.Add(paramALICO);

crystalReportViewer1.ParameterFieldInfo = myParams;
report.SetDataSource(dataSet);

crystalReportViewer1.ReportSource = report;

Enjoy

based on you additional details, looks like you need to display data fetched from DB.

Use query or dataset as the dataprovider to your report and then in design view of crystal you can use 'Table' as one of the dataregion. Bind the columns of values expected from DB.

Now if 5 values returned you will get 5 rows (in the table in UI at runtime) and if 3 then 3 rows.

Hope that helps.
P.S: you will need crystal designer for it. (its not free - its licensed!)

Solution 6

While binding data Runtime, the performance of Crystal control is not that great compared with binding data though queries.

May be This will give u an Idea , or may be i dont fully understand the question

C#

private void ReportContentStyler(ReportDocument MyRep)
 {
     int padding = 1070;
     for (int i = int.Parse(Session["StartFromdic"].ToString()); i <= 11; i++)
     {
         MyRep.ReportDefinition.Sections[1].ReportObjects["Parm" + i.ToString() + "1"].ObjectFormat.EnableSuppress = true;
         int myWidth = MyRep.ReportDefinition.Sections[1].ReportObjects[0].Width;
         MyRep.ReportDefinition.Sections[1].ReportObjects[0].Left =
             MyRep.ReportDefinition.Sections[1].ReportObjects[0].Left + padding;
         MyRep.ReportDefinition.Sections[1].ReportObjects[1].Left =

         MyRep.ReportDefinition.Sections[3].ReportObjects["Line25"].Left = MyRep.ReportDefinition.Sections[2].ReportObjects["Line25"].Left + padding;

         MyRep.ReportDefinition.Sections[3].ReportObjects["Line28"].Left = MyRep.ReportDefinition.Sections[2].ReportObjects["Line28"].Left + padding;

     }
     int lineID = 20;
     for (int x = 0; x <= (11 - int.Parse(Session["StartFromdic"].ToString())); x++)

Some lines cant be moved, need to use some hack.

VB

Private Class Line

    Public Shared Sub Move(ByVal Line As Object, ByVal HorizontalMove As Integer)
        'Taken from IL decompile
        Dim Hack = Reflection.BindingFlags.NonPublic Or Reflection.BindingFlags.Instance
        Dim RasDocument = Line.GetType().GetProperty("RasDocument", Hack).GetValue(Line, Nothing)
        Dim RasReportObject = Line.GetType().GetProperty("RasObject", Hack).GetValue(Line, Nothing)
        Dim iSCRReportObject = RasReportObject.Clone(True)
        iSCRReportObject.Left += HorizontalMove
        iSCRReportObject.Right += HorizontalMove
        RasDocument.ReportDefController.ReportObjectController.Modify(RasReportObject, iSCRReportObject)
    End Sub

End Class

Solution 2

I dont want to add runtime parameter i want to generate report runtime
suppose there are 3 values coming from database then those three value should be display in report and suppose there are five values coming from database those five values should be display in crystal report.

Dear Deepaji,
I'm very close enough for your problem. can u please mention your DB and the exact scenario of your project. If you are using MySQL 5.0 as I am doing. Then You definitely at hard time as the MySql Bridge is not so much mature enough. However if you're using Microsoft based DB, then you can create DataTable within DataSet,fill the DataTable with dynamic fields and use the Table afterward in the report.
