jqGrid - hide column in form edit but visible in grid

I know jqGrid can hide the column in grid but visiable in edit form. Is there options for the other way around? In other words, does jqGrid have the option to hide the columns during form editing but visible in grid?

One useful scenario would be have a concatenated column composed of more than o开发者_如何学JAVAne columns, such as lastname + ' ' + firstname.

Look at my previous answer jqGrid: Disable form fields when editing. It seems that is exactly what you need.

If you want to create some custom fields in the edit form which will look like not as standard fields another answer could be also interesting Add multiple input elements in a custom edit type field.
