Dependent Select box template in the Grid

Hi All,

I would like to know if any one has implemented a dependent Select box template within the Grid. For example, If column one has a select box template that depicts a List of Categories, then after Selecting a Category from the first list the correspesponding Sub Categories should be loaded in the second Select/list box template within the second column.

Please give your suggestions.

HI.
I'd like to know how to do it.

Bye
