    I have a grid that is bound to a dataSource, and the dataSource has the required field validator set for several fields.  This works fine if I use the grid's built-in popup editor; if I leave a required field blank then I will get notified when I click "Update" in the popup editor.  However, if I use a custom popup editor (via kendo template) then the required field validation does not fire and I am able to save a blank value.

    I have created a sample that exhibits this behavior:

    If I modify my dataSource to include customValidation, that will fire in the custom popup editor but I don't think I should have to go down the path of defining a custom validation since the field is already marked as required in the dataSource (and it works when using the default popup editor).

    This seems like a bug.  Is there any workaround?

    You have to manually add the required attribute to your input element. Kendo Grid does not add validation attributes to custom templates. I believe the customValidation rules work because they get attached through jquery based on the input element name.

    Hi Sean,

    Tim is correct - the "required" validation attribute should be manually added to the editor when custom editor is defined in order to enable the "required" validation (the validator validates only elements with that attribute against the "required" validation). On other hand the custom validation is executed against all editors inside the editor template which is the reason for current behavior.
