Hi Tony,

This is in your Demonstration page. By going to Integrations -> UI Datepicker

Select any row. It changes into edit mode and the first text box now has focus.

By pressing Tab you cycle through the available text boxes (it goes from left to right, alternating between the text boxes making it easy to edit). This behavior is also available in the demonstration page: Row Editing – Basic Example, after clicking “Edit Row 13” and selecting the first text box.

Back to the Datepicker, once you've tabbed or clicked on the datepicker field, the calendar appears. Once you select a date it loses focus of the date textbox, preventing you from tabbing to the next available text box for edit.

This is the same in all browsers, IE6,7 and Firefox (that I've tested)

I then proceeded to implement your demonstration code into my own code and it experienced the same kind of behavior.

Thank you for your time in looking into this issue

Kind Regards
