Create a parameter field in Crystal. You can set its value via the parameters collection at run-time.

CrystReport1 plc = new CrystReport1();
plc.DataDefinition.FormulaFields["Formula Fild Name*"].Text = "" + textBox1.Text + "";

---

CrystReport1 plc = new CrystReport1();
plc.DataDefinition.FormulaFields["Formula Fild Name*"].Text = " '" + textBox1.Text + "'";

     ReportDocument dailyIssueDocument=new ReportDocument();
   var fD = dailyIssueDocument.ReportDefinition.ReportObjects["fTextBox"] as TextObject;// fTextBox is a Text object that i take to my report for showing form select date
   if (fD != null){
       fD.Text = fDate;//This is Date field that comes from  form text box
}
