Thanks!

i forgot to say that of course my grid and my other fields are binded and it works fine, but now i'd like to have some checkboxes displayed in the tab below if the category of the selected item in the grid is "x" and some other checkboxes displayed if the category is "y".

please, anybody can help me here?
