Calling multiple crystal reports using radio button

Question

Hi ,

 

I have to create one form in c# with data from Oracle, i managed to run the crystal report from c#form but i  have three diferent reports report1.rpt , report2.rpt and report3.rpt. if i am pressing the radio button 1 first report should report1.rpt should be viewed and if i choose radio  buttton 2 then report2.rpt should run. Basically there are two text fields as parameters on the forms which will be passed to fetch the data from oracle . How can i go about it. Appreciate if someone can help.
