Well… here is the solution….

$(“#list”).jqGrid('navGrid','#pager',{

edit:true, edittitle: 'Modify a Deployment',

add:true, addtitle: 'Add a new Deployment',

del:true, deltitle: 'Delete a Deployment'},

{// edit option

beforeShowForm: function(form) {

$('#branch', form).attr(“disabled”,”disabled”);

},

editCaption: “Edit a Deployment”

},

{// add option

beforeShowForm: function(form) {

$('#branch option[value=””]', form).text('Select a branch')

$('#branch option[value=””]', form).attr(“selected”, “selected”);

$('#branch', form).attr(“disabled”,””);

},

addCaption: “Add a Deploymet”

},

{// delete option

top:50,

left:100,

width:500

},

{// Search option

multipleSearch:true

},

{// view option

}

);

I hope that will be useful for us
