Thank you for writing us.
The export providers(GridViewPdfExport, GridViewSpreadExport or GridViewSpreadStreamExport) utilize Document Processing libraries (DPL). These libraries can change the DPI awareness of the application at runtime because the are referencing assemblies which are used in WPF.
If your WinForms application is not a DPI-aware, the application may become DPI-aware at run time (when the DPL functionality is used). If you intend to use your application on machines where the DPI scaling is larger than 100% you should explicitly set the application to be DPI-unaware:
sender, EventArgs e)
GridViewPdfExport exporter =
HiddenColumnOption = HiddenOption.DoNotExport,
HiddenRowOption = HiddenOption.DoNotExport,
SummariesExportOption = SummariesOption.ExportAll,
Process_DPI_Unaware = 0,
Process_System_DPI_Aware = 1,
Process_Per_Monitor_DPI_Aware = 2
More information how to make a DPI-aware application can be found on the following links: WinForms Scaling at Large DPI Settings–Is It Even Possible?
In regards to your issue at design time, it is recommended to edit the designer file under 96 DPI (100 %). More information about Microsoft`s guidelines can be found here:
I hope this information was useful. Should you have further questions please do not hesitate to write back.
