Is their any other way to create co (Combo box) or
coro (Simple Combo box) except XML head, as we don�t want to control the data
contents of the combo box list via XML instead want to set them in our
JavaScript function
You can use getCombo(colIndex) and put(key,value)
methods.
mygrid.getCombo(5).put(1,2);
//put value “2” with key “1” to combobox in column
with index=5
