CONTROLLER

[HttpPost]
public ActionResult _EditCategory(CategoriesViewModel categoriesViewModel)
{
    Categories category = entity.Categories.SingleOrDefault(x => x.sno == categoriesViewModel.sno);
    category.IsShowcase = categoriesViewModel.IsShowcase;
    category.Name = categoriesViewModel.Name;
    category.OrderNo = categoriesViewModel.OrderNo;
    try
    {
        entity.Categories.Add(category);
        entity.SaveChanges();
    }
    catch (Exception ex) { }

    return PartialView(categoriesViewModel);
}

I debugged it. I cant post only sno of model(sno is the primary key of Model and uniq). Model is posted with parameters, but only sno is not posted.

How can I achieve this? THANKS.

First thing that concerns me in your code is the id option which you use – jqGrid doesn’t have such option. If that option was suppose to make jqGrid resolve the row id out of your model, than you should have use jsonReader for this purpose:

$("#grid").jqGrid({
    ...
    jsonReader: {
        repeatitems: false,
        id: 'sno'
    },
    ...
}).navGrid('#gridpager');

Now assuming that your rows ids are bound properly, you can use prmNames option to tell jqGrid that it should POST row id under sno name:

$("#grid").jqGrid({
    ...
    jsonReader: {
        repeatitems: false,
        id: 'sno'
    },
    prmNames: {
        id: 'sno'
    },
    ... 
}).navGrid('#gridpager');

This should resolve your issue.

P.S. Most probably you don’t need sno column in your columns model (and columns names) definition as you use it only for row id.
