I viewed the report but got an error when exporting the report.

In test project, I can export the report normally but in main project i got an error :"Unable to export the document due to failure of connecting Report Service" when export report. Anyone experienced please help. Thank you!

Hi le hai anh khoa, 

Thanks for your interest in Syncfusion products. 

The reported issue may occur when the dependent assemblies of ReportViewer referred are not in same versions. So, could you please ensure whether all the assemblies referred in your main project with same version.
