Q: How to set value for nth.child numeric text box input field I want to know how to set value for nth-child numeric text input field. I tried this inside the kendo grid save event as below. 
e.container.closest("tr").children(':nth-child(10)').val(8);

how can I do this?

A: I assume the input is inside of a table cell, right?. If that's the case, you could use eq() function...
e.container.closest("tr").children('td').eq(9).find('input').val(8);

NOTE: As @Taufik and @guradio pointed, the index in eq() starts in 0 while in nth-child starts in '1'.
I hope it helps
