Hi,

Hi,

I am currently working with crystal report & i am using crystal report viewer & crystal report source. Crystal report viewer & Crystal report source that i put in update panel because when we press "Next" button ( i.e crystal report viewer property ) it doesn't allow post back to page. But problem will occur when i press Export Option ( i.e crystal report viewer property ) to select file formate (PDF), will not be opened due to update panel.
I have already done Research & development on it & i found one solution & i.e. fire trigger (like below).
<asp:PostBackTrigger ControlID="CrystalReportViewer1" />


Page will be post back (that i don't want) & pop up export option (that i want), when i am going to write this trigger "<asp:PostBackTrigger ControlID="CrystalReportViewer1" />" . So if i do it like this it is not good for my project that each & every time postback.

If any one knows better option that while pressing next button page will not going to be postback every time and Export option (of crystal report viewer ) will pop up. Is there any script for it or other option.

Thank you,
Ronak
