Answer / richard des jardins

What I have done is create a protected sub OR void that
sets all the parameters including the SetDataBaseLogon;
let's call it LoadForm. I am not sure you you are loading
the report on initail page load or if the use has to
trigger an event before it is loaded. If it is on page
load, call the method on page load. If it is loaded after a
user interaction,I call the LoadForm() then set a sesiion
variable inticated that it has been loaded. Then in the
page load, Id add a conditional of that session exists or
is NOT nothing, then call LoadForm.

This is assuming you are using a ReportViewer. The
ReportViewer will handle State so paging should work as
expected.
