Hi Ashok,
We are not able to reproduce the issue and we suspect it was due to required Syncfusion.shared.Wpf.dll assembly not added in the project.
Can you check the visual studio output window to see any errors? Also, if you have referred Syncfusion.shared.wpf.dll, can you please make sure you have referred the right version as Syncfusion.sfgrid.wpf.dll.
If you still face this issue, please revert to us with project file or sample that will help us to provide better solution.
Thanks,
Sivakumar
