Additional meta data in the datamodel

[stoodin]

Hi,
I there anyway to keep additional meta data in the datamodel and what is the best way to do that?
For example in the grid I have a dropdown column which I populate from DB and show a description property only which maps directly to the grid datamodel.
Each object in the dropdown has a pkey but I am not sure how to store it within the grid and more importantly how to get the pkey when user selects the description from the dropdown.
Thank you as always.

In the grid dataModel, pkey can be stored in a hidden column.

while json data format can be used for the editor.options, pkey can be stored as valueIndx while description as labelIndx.

Please refer to the API:
http://paramquery.com/pro/api#option-column-editor

you might also need to implement editor.getData callback to fetch both pkey and description from the editor.
