Hi Sergiy, 

Sorry for the inconvenience caused.


The reported issue has occurred due to mismatching of DLL version in your sample. As you are using and if the frame wok version is 4.0, then the DLL version should be 12.2400.0.36. Please check the ‘bin’ folder and refer the following table for DLL reference.

 .Net Frame Work Version

DLL Reference







Please follow the steps below:

1.      Open the Syncfusion Essential Studio and click on Explore sample.

2.      Click on samples and open web folder, you can get the bin folder inside.

3.      Check the version of DLL inside the bin folder.

DLL version should match the frame work version you have used. And also, please check the webconfig file in your sample.

All the assemblies referred inside the webconfig file should match your .NET framework.


Please let us know if you have further queries.
