Grid.load interaction

Hello,

I am trying to populate data from one grid to another - get the id of the selected row from the first grid and populate data based on that id in the second one. Am using:

But instead getting the values for that particularly selected row rID i get all the data.
Any suggestions how to filter the data in my second grid based on the row selected in the first one - pls help

All right, i realize i had a bad approach in what am trying to do.
So now my question is kinda silly but still I am reading the forum page by page and still can’t find any way to make the grid render particular data from my source.

Any ‘tips & hints’ will be most appreciated

[SOLVED]

Am pretty sure this isn’t the best way to complete the goal. But still it works!
I reworked my grid_connector.php to scoop incoming requests and to write a proper xml tag for my Second grid. Also some modifications ware made in base_connector.php just to arrange my tags properly.

P.S. Am using this just for fun. But if I decide someday to use it for commercial use, would there be a licensing problem with my modified scripts?
