jQuery Grid Plugin - jqGrid

I used cellsubmit: 'remote' to force an ajax call.

What does 'clientArray' do and for what is it used for?

Also, how can I add post data to the remote ajax request on save, I tried the following and it did not work:

            beforeSubmitCell: function()    {
                $(item).setPostData({'oper':'editCell'});
            },

so that the server knows what kind of operation is performed; i.e. edit of entire row, save of a new record, delete or editing a specific cell only.

Thank you Tony! Yes, I simply appended my parms to the url, thanks again. Maybe we can add a parm to indicate the actual field name updated during a cell update so that a person does not have to check each field to see which one was updated, maybe there is a easy way to do it with the existing framework?

Example, the user can update Street Address 1, 2, 3, City, State zip, etc, on the server I have to check on cellEdit which one is not null to figure out what had changed.

Added the following line to the jqGrid to set a new property for the posted data, but it is not extended/added in grid.celledit.js line 145 in method saveCell. In lines 153 can we add an extend to add the additional custom properties to the post?

            beforeSubmitCell: function(id, cellName)    {
                $(myGrid).appendPostData({editCellColumn:cellName});
            },

So basically the appendPostData works but is not added to the postData property in saceCell. is this an issue or is there another way to do it?
