Crystal Report Viewer for .NET (VB): Report Loads, Viewer not visible

Former Member

I have a problem that has been hindering my progress for quite some days now. The problem is the that crystal reports viewer throws no error yet will not display. I have came across quite a few other forum posts of a similar nature with 'fixes' that haven't helped me in anyway.

As you can see from the attached image their is a placeholder + html being generated in the source code so I know that the viewer is there however its not visible. I have attempted various fixes such as copying over the Crystal Reports aspnet_client folder and pointing the viewer to use those files in the web.config.

  <sectionGroup name="businessObjects">

      <sectionGroup name="crystalReports">

        <section name="crystalReportViewer" type="System.Configuration.NameValueSectionHandler"/>



This has proven unsuccessful.

The page is also being ran locally so one would assume it would be able to use the crystal reports files that are installed on my machine.

Usually if there is an error in the report it will either throw an exception or will show the viewer but the report will be blank which is fair enough. That is expected however in this scenario the viewer just refuses to show.

My suggestion (should anyone have a fix as this seems to be bothering alot of people) is that a definitive fix thread is started and made visible.

If anyone has experienced this issue or has a fix it would be most appreciated. Thanks.

Hello Craig

There are no fixes, as there are no bugs... There are configuration issues that need to be addressed by the developer of the .NET application, but no bugs that I am aware of.

Since you you have came "across quite a few other forum posts of a similar nature", you have probably also seen that the configuration depends on the version of Crystal Reports used, which you did not specify in your post. Once we know the version of CR, version of .NET and OS, we should be able to help. Also, let us know if this is an issue on your development computer or after you deploy the app.
