Hi,
u r right. u can use preserveDataModel="true" in
datatable. if it is true then action method surely be
invoked. But the problem is if u want to delete the
row from table and afetr deletion you want to display
the same page then row will be deleted from DB but
page will contain that row. I am looking for the soln.
regards...
