This code is working fine but when I enter a value in text box then everytime it shows the similar value. If I close the project and run it again, then it shows the correct answer but when I enter the value again the second time, the crystal report shows me the previous report.

CrystalReportViewer1.RefreshReport();

is not working properly

~~PLEASE GIVE ME ANSWERE QUICKLY~~

Thanks
