Not sure what you want to do but you can check the examples page to see what could be done with jqGrid (http://trirand.com/jqgrid/jqgrid.html)

Robert, check the pathtojsfiles var in your jQuery.jqGrid.js file

1) Using the loadComplete event. Something like:

gridComplete : function() {

Please, add the beforeSubmit event as above and put the id getting the value from the row selected.

If this field is your PK, you know it will be empty if you are adding a new record, otherwise it shouble have the value from the selected row

You can use the beforeSubmit event for the action you are executing and add any value to the editData

Sorry It

When you update a database jqGrid sends the parameter “oper” when (you guess) the operation to be done. “oper” takes the following value,”add” – Add a new record,”edit” Update a exsiting record and “del” delete a record.

You can also add “custom” buttons and assign any string to be recognized by your server side code as a valid operation.

Moreover, Adds any data you want but typically the values for the fields in you editing form…
