Thank you for using Syncfusion products.
All the Syncfusion referenced assemblies in the project need to be shipped. Please check on the following points.
1) If your application references the assemblies in a specified folder, the path for these assemblies should be maintained in other systems too. Please check the other systems have those assemblies in the respective path.
Thank you for updating us.
The provided sample is not executing from our side too. On further analysis we found that, 3 assemblies were referring from a hint path. Please remove the hint path from its project and try by recompiling the sample. Make sure all the assemblies are set copyLocal TRUE.
Please find the screen shot referring the issue in the following link.
Please try the above and let us know if this resolves the issue.
On analyzing the given sample further, we found that the library Syncfusion.SfSpreadsheet.WPF.dll is referred in your project which requires another library Syncfusion.SfGridCommon.WPF.dll. If you have installed Syncfusion dashboard, then this assembly will be referred from GAC by default otherwise it is mandatory to have Syncfusion.SfGridCommon.WPF in Release folder. So kindly copy this assembly from pre-complied assemblies (i.e. C:\Program Files (x86)\Syncfusion\Essential Studio\220.127.116.11\precompiledassemblies\18.104.22.168\4.5) to the project’s Release folder. This should resolve the issue.
