Referencing DataTable rows within the table column header

Hello All,

I am creating a table with a DropDownChoice component in the header of one of the columns. When a selection is made in the drop down in the column header, I want to update all of the rows in the table.

Would the following snippet be the best approach to reference each row Item component from the column header, or is there an alternative to using the get() method?

Thank you in advance,

WebMarkupContainer container = ((WebMarkupContainer)dropDownChoice.findParent(DataTable.class).get(1));
DataGridView gridView = (DataGridView)container.get(0);
for(int i = 0; i < NUM_OF_ROWS; i++) {
Item item = (Item)gridView.get(i);
// do row updates
