JqGrid: Autocomplete in form fields - jqgrid

Question

I am using free version (latest) of jqgrid with MVC c#.
I have form fields setup. When the user clicks add in the footer button (add) it shows a modal popup with all the form fields.
I want my first textbox in the form field to autocomplete, ie when they start typing their empployee number in the textbox, I should query my mvc controller and fetch the data and then prefill if there is a match. Once that prefills I also want to update 2 more label on the form, firstname & lastname. Also the button should be disabled until the correct id is fetched in the employee textbox.
Not sure how should I go about this. I can share my sample grid that I have used.
Thanks
<script type="text/javascript">
$(function () {
"use strict";
var $grid = $("#list");
$grid.jqGrid({
url: '#Url.Action("GetData", "Home")',

loadonce: true,

colModel: [
{ name: 'empid', index: 'empid', editable: true, editrules: { required: true}},
{ name: 'fname', index: 'fname', editable: true, editrules: { required: true}}, //currently these are texbox, but I want this to be label which gets filled based on the empid
{ name: 'lname', index: 'lname', editable: true, editrules: { required: true}},
{ name: 'address', index: 'address', editable: true, editrules: { required: true}}

}).jqGrid("navGrid")
.editGridRow("new", properties);
});
Updated:
If there is also option to use onkeyup, mouseover etc on the textbox so that I can validate whats entered in the textbox and then also update other textbox based on this value

Answer 1

I have done this by using keyup event instead of using autocomplete.
Relevant code as below:
colModel: [
{
name: 'empid', index: 'empid', editable: true, , editrules: { required: true },
editoptions:
{
dataEvents: [
{
type: 'keyup',
fn: function (e) {
$.ajax({
url: //call to my method in my mvc controller,
data: "empid=" + $(this).val(),
type: "GET",
success: function (data) {
//validate and populate other fields here
}
else {
}
},
error: function (passParams) {
// code here
}
});
}
}
]
}
]
