Hi ,

I am very new to javascript (jqgrid).I have started looking into tree grid.How to get these values" $n_lft = (integer)$_REQUEST["n_left"]; $n_rgt = (integer)$_REQUEST["n_right"]; $n_lvl = (integer)$_REQUEST["n_level"];".
I am just trying out the sample tree grid in Jqgrid Demo.I am not seeing any of the above listed parameter in the postdata of my servlet.Can somebody explain me how this treegrid works?

Thanks in advance,
Vmani
its not data store.Its the Db temp table.Will that be possible??
Hi

In my code a procedure creates a temp table to populate the data in an EXTJs grid .This grid is a drag drop grid.So i can drag and drop rows from right to left ,when i click save i need to save this changes.Is it possible to update the same temp table which i used to populate data?

Thanks,
Vmani
