Hello, Guo,

The Kendo UI Grid for ASP.NET Core checkbox selection provides multiple selection of the rows. The grid's selectable property is a different functionality(multiple cell in your case) and it is mutually exclusive with the checkbox selection:

https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/columns.selectable

I tested the provided configuration and while no error is thrown, it is not a recommended configuration nonetheless. If you let us know what is the desired behaviour that you wish to achieve, we could suggest an alternative. 

For example, what would you expect to occur when the user clicks on the checkbox? Should the entire row be selected?

Look forward to hearing back from you.

Kind Regards,
