I have a multicolumn key in db table and it also means, that my grid row is identificated by more than one column. Is this posible to do somethink like this in jQGrid?
I think you'll need to combine the keys. You could simply append them (if they are string), or something like this key = key1 * 1024 + key2. Make the constant big enough to accomodate the complete expected range of key2, but smaller than whatever limits exist in javascript.
