To Pass TextBox Value to Crystal Report without using Database

To pass TextBox value to crystal report without using database :

1. First create a parameter in the paraeterField in the DatabaseFileds, name it crParam.
2. ReportDocument cryRpt = new ReportDocument();
   cryRpt.Load(@"C:\Documents and Settings\Administrator\My Documents\Visual Studio 2008\CrystalReportsWithParam\CrystalReportsWithParam\CrystalReportsWithParam\CrystalReport1.rpt");
   

   ParameterFieldDefinitions crParameterFieldDefinitions ;

   ParameterFieldDefinition crParameterFieldDefinition ;

   ParameterValues crParameterValues = new ParameterValues();

   ParameterDiscreteValue crParameterDiscreteValue = new ParameterDiscreteValue();

   crParameterDiscreteValue.Value = textBox1.Text;

   crParameterFieldDefinitions = cryRpt.DataDefinition.ParameterFields ;

   crParameterFieldDefinition = crParameterFieldDefinitions["crParam"];

   crParameterValues = crParameterFieldDefinition.CurrentValues;

   crParameterValues.Add(crParameterDiscreteValue);

   crParameterFieldDefinition.ApplyCurrentValues(crParameterValues);

   crystalReportViewer1.ReportSource = cryRpt;

   crystalReportViewer1.Refresh();

Now drag and drop that parameter crParam on crystalReport where ever you want to display in that's it.
