I am working with vision , and have a report viewer with 7 pages, the script will check if each page has atlest 1 row for a particular serial number tag , if its empty it wont print that page, the only problem here is some times i am printing blank pages, and if i try to run same serial number in the designer the report viewer is loaded with proper data, something is not working sometimes. I cant find it, any suggestions would be greatful.
I am executing the script to print pages 1 after other, i have 3 seconds delay between every page for the report viewer to load, but looks like the page is not loaded with 3 seconds delay, increasing the delay also didnt help. the pages load correctly if i check in designer ( without any delay)
