In our application we are using radgrid where we are going
to select three things like a,b,c from combo box where 'b' depends on
'a' and 'c' depends on 'b' (selected change event of combobox) after
clicking on add it should add to grid but not to database. And i should
be able to delete, edit rows.When i Save my page then all the rows
should be read and stored in the table.
