Extremely slow response on SetDataSource command

Hi,

I realy hope someone can help me.

I have a report with 44 sub reports, in the report header.

The processing is very simple, and the amount of data isn't large, i get the slow loading even when there is as little as 2 rows of data in the data set.

This report used to work fine on Crystal 9 and .net 1.1

we have now upgraded to .net 3.5 and Crystal 10.0 with SP 6.0

As soon as my application hits the SetDataSource command, it takes anywhere from 1 minute to 5 minutes.

Note that in the crystal designer it displayes the report instantly.

Note that in crystal 9, it displayed the report instantly.

I'm at my wits end, and at the point of throwing the report out totally, so i would appreciate any help.

The reason for the 44 subreports, is that i have a main report, showing one total for each subreport, and when you click on it, it displays the detail.

If there is a better way of doing this, i'm also open to any suggestions

Thank you in advance and anticipation
