How to show all form errors together in jqGrid?

When there are any errors in 'edit' or 'add' form, errors are shown one by one on top with red background. Is there some variable which could be set to show all errors together? I couldn't find any such setting.

This question was also asked开发者_JAVA技巧 on the jqGrid forum, but it isn't answered yet. (Last comment by David, 2011/03/17 08:52 )

Edit:

When I click on "edit", a form is opened. Suppose there are few "required" fields on that form and I leave them all empty. Now when I press "submit" button on form, only error about the first "required" field is shown, not for all the required fields. When I rectify first required field and press submit again, only then it tells about second required field. I want to show all errors about required fields once and together. I hope that clarifies the question.
