edatagrid - is it possible to hide some fields when posting data?

[Stefan B.]

We use edatagrid with the saveUrl and updateUrl.

Every time all row object data send to the controller if we add or edit a row.
But some columns are not editable (only information fields) and this field values should not send to the controller.
Also some "row object data" not shown on the table as column. This fields also send to the controller.

Code:

		idField: 'idString', //this field is used for editing and delete rows with a datagrid
		saveUrl: 'add.do', //to add a new record
		updateUrl: 'edit.do', // to save updated data 

My question: How can we configure the edatagrid so that only some row data attributes send to the controller?
