Answer 1

To return from function you can use return false or e.preventDefault(). You have returned from .each function take that statement outside .each or use e.preventDefault()
grid.Column("Title",
format: #<text>#Html.ActionLink((string)item.Title,
"Details", "Home", new { id = item.ID }, new { onclick = "getValueUsingClass1(event)" }
function getValueUsingClass1(e) { debugger;
$(".myCssClass:checked").each(function (){
chkArray.push($(this).val());
var selected;
selected = chkArray.join(',') + ",";
if (selected.length > 1)
{
alert("You have selected " + selected);
}
else { alert("Please at least one of the checkbox"); }
});
e.preventDefault();
//OR
return false;
}
