Page navigation buttons are not working sometimes.

Hi,

I am working with asp.net and Crysatl reportXI R2.

I am displaying the repors on the web ui with the help of Crystal report Viewer and i have displayed the page naviagtion butttons on the viewer.

The problem what i am facing is that the page navigation buttons are not working sometimes. Especially with the First Click on the Next or Last Button.

also if there are more than 1 page (Eg:No of pages2)i would like to display as 1/2 in the viewer.

At present what it showing is /1+.

Could any one please tell me how to solve the above said problems

Regards,

smitha.
