Hi
For implementing edit functionality in JQgrid we have to set editable property to true in JQgrid column model.
Eg.
colModel: [
{ key: true, hidden: true, name: 'Id', index: 'Id', editable: false},
{ key: false, name: 'TaskName', index: 'TaskName', editable: true },
{ key: false, name: 'TaskDescription', index: 'TaskDescription', editable: true },
Here in this example Id column will be not editable, but
Task name and Task Description are editable.
Also For Your Reference you can refer my blog.I have created sample application demo on JQGrid MVC.
