jQGrid, how to make a column editable in the add dialog but not during (inline) edits

Question

I have a jQGrid with a column that I only want to be editable when adding a new row.

I've seen examples of how to do this when edits and adds are both happening in a dialog but is there a way to do this with in-line editing?

I've tried using grid.setColProp() in beforeShowForm:, but this doesn't work ( the column remains read only and is not present in the add dialog).

Example of dialog based column enable/disable:

Because you use the example from my old answers (this and this) I feel that I should answer also on your question.

In the old example all fields, which can be modified during Add or Edit dialogs, has property editable:true. The fields which should be shown only in the Add dialog will be made hidden inside of beforeShowForm event handle. In the same way we can temporary switch some fields to editable:false before call of the editRow method and reset back to the editable:true immediately after the call:

onSelectRow: function(id) {
    if (id && id !== lastSel) {
        grid.jqGrid('restoreRow',lastSel);
        var cm = grid.jqGrid('getColProp','Name');
        cm.editable = false;
        grid.jqGrid('editRow', id, true, null, null, 'clientArray');
        cm.editable = true;
        lastSel = id;
    }
}

You can see this live here.

UPDATE: Free jqGrid allows to define editable as callback function. See the wiki article. It allows to make the column editable in some rows and holding non-editable for other rows.
