Hi,
Situation :
We have a list of cheques where a user can select (more that one) and using reportviewer to print it by pressing a print button (please refer to attach image)
Problem :
On first print activitiy, printing is success, but if the user need to re-print or select another cheques from the list and press the print button, an error "Report instance with ID 'null' not found" will occur.
Need some advise to fixed or a workaround.
Thanks in advance.
