Hi Santosh,

We already received a similar query from other customers and this issue can be resolved by following the below steps.


  1. Update the NuGet package for all Syncfusion controls to the latest version
  2. Delete the bin and obj files, then run the sample again.

 If the issue persists, please let us know the version and names of the Syncfusion NuGet packages that are currently used in your project.
