I have a JQGrid with a hidden column, I would like the data in this column to be posted back to the server when the user edits it in the edit dialog box.

As it stands, the only way I can see this form data in the postback is when using the column property Editable = true, however, this then displays a text input box on the dialog. With Editable = false the input box is hidden but the value is not in the postback.

Having the property displayed in the edit dialog is not ideal as I don't want the user to be able to change the value, but I need it posted back to the server for business logic reasons.
