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

When I look at the actual http post, the id is in there.
My method on my controller looks like this

public JsonResult EditClients(string address, string clientdescription, string clientname, string contactname, string contactnumber, string country, string id, string province)

Everything has a value except id, it is empty.

I got around though, in the

Here is the really strange thing, the id is in the post to the server. When the request hits the controller method, the id is an empty string.

I have tried everything I could think of. I appreciate the response, but I would really like to know what I am doing wrong.

Does my method need a certain return type?

 // --- edit options ---
            { height:100,
              width:500,
              reloadAfterSubmit:false,
              beforeSubmit: function() {
                 var sr = jQuery("#list").getGridParam('selrow');
                 var rowData = jQuery("#list").getRowData(sr);
           
                  this.editData = {"co_motivo_desa" : rowData['co_motivo_desa']};
                  retarr = {"co_motivo_desa" : rowData['co_motivo_desa']};
                  return retarr;
              }

Here I am just adding "co_motivo_desa" to the request...
