i have added kendo grid in my asp.net core 2 project ..
i have a checkbox column in it which is bound to IsVisible field
when i click edit or create button , i get a validation error which is 'The IsVisible field is required.'
i think there is a bug with the grid validation , because a checkbox always has a selected value (checked or not checked)
you can see the issue by adding or editing a row in telerik inline editing sample : https://demos.telerik.com/aspnet-core/grid/editing-inline
