Hi

I have converted a local report in a windows form application from
VisualStudio 2008 to VisualStudio 2010.
In the report viewer the report is correctly visualized, but, sometimes, in
print layout (or if i print the report) I obtain this exception: "An error
has occurred during report processing" "Index was outside the bounds of the
array".
The report is binding to a object data source, if i delete some object from
my data source the error disappear.

Thank in advance
Giorgio

Hi Giorgio,
Is your object in your data source shared by multiple threads or possibly
be changed concurrently when you tried to print the report?

If this is possible, I recommend that you first clone the dataset and set
the cloned dataset as a data source to your local report. In this case, the
data is stable for your local report.

Best regards,
Charles Wang

Hi, thank for your reply.
My object DataSource is not shared and is not changed after is binding to
the report, however I try to follow your suggestion and try to use a cloned
dataset

Is it possible that when you print the report other user/thread changes the
data source of your report? If so, you need to forbid the change.
