jQuery Grid Plugin - jqGrid

Hello,

I use jqGrid since a few days and i find it extremely powerful.

However, i have a problem with an input. I want jqGrid check if data post is a correct date : dd/mm/yyyy only if the input is not empty.

Params of my colModel is :

{name:”date_obtention”,
index:”date_obtention”,
align:”center”,
edittype:”text”,
editable:true,
sortable:true,
editoptions: {size:15, maxlength: 10},
editrules: {required:false, date:true},
datefmt:”dd/mm/yyyy”}

I force required to false but jqGrid automaticly control the date.

If you have any suggestion, you're welcome.

Thanks
