Report Viewer doesn't Preview after Export

[Former Member]

The Windows Application has a C# class for a Report Menu which calls any one of several reports. The Report Menu allows the selection of various parameters for the report being called and then calls a C# class that builds a sql query and sets it as the report data source and sets the report parameters then opens the report in Crystal report viewer.

The report displays in the viewer and I can click on the close button and the Report Menu in the App allows me to select a different report with different parameters, no problem.

However, when any report is previewed in the viewer, before clicking the close button, I can click on the Export button and successfully export the report in whatever format and get "Export Completed". Then click on the close button and I am back at the Report Menu in the App. Try to preview any report now and it will crash. The error messages vary somewhat depending on the report selected. I can set a break point at the beginning of the class (that builds the query and sets the data source) and hit that break before doing an Export - -

but after the export the break point is never hit. Its like the Report Menu class is somehow trying to display the report without calling the report building class!

OK. A good place to start is with the basics.

Step 2 Asking Your Question; Provide Enough Information

So, please provide the necessary info as per the above.

Also:

" The error messages vary somewhat depending on the report selected. I can set a break point at the beginning of the class (that builds the query and sets the data source) and hit that break before doing an Export - -"

Please provide the most common error you get, else provide all of the errors.
