Recordselectionformula in crystalreport giving error

[srm2010]

In My windows application selection formula having textbox value gives error.
Not recognising expression without textbox it is working fine.
CrystalDecisions.CrystalReports.Engine.ReportDocument rpt;
rpt = new CrystalReport6();
rpt.Load(@"H:\CrystalReportsApplication1\CrystalReportsApplication1\CrystalReport6.rpt");
// rpt.RecordSelectionFormula = "{cashtbl.stdid}=7";---working fine
or
//the below code gives error saying number is equired
rpt.RecordSelectionFormula = "{cashtbl.stdid}='" +Convert.ToInt32(textBox2.Text) + "'";
crystalReportViewer1.ReportSource = rpt;
crystalReportViewer1.Refresh();

hello !

rpt.RecordSelectionFormula = "{cashtbl.stdid}='" +Convert.ToInt32(textBox2.Text) + "'";

in above line you are converting textbox value in to integer and after that you are using '' and dealing like a string .use this

rpt.RecordSelectionFormula = "{cashtbl.stdid}= +Convert.ToInt32(textBox2.Text);

Hope this will solve your prob,if yes please mark your thread solved :)

Yes I could get the date working using datepicker.value but I can see both date and time coming in crystalreportviewer.I tried settings in crystalreportviewer but does not work.
Thanks for your help in advance.
