Answer 1

Try changing your data to this:
var data = [{id:"John",value:"57"}];
EDIT
Here's a sample of what I think you're trying to do:
var data = [{NAME:"John",AGE:"57"}];
$('[id$=Name]').autocomplete('CallBack.aspx', {
formatItem: function(item) {
return item.NAME;
}}).result(function(event, item) {
location.href = 'somepage.aspx?age=' + item.AGE;
});
Basically you needed to capitalise return item.Name to return item.NAME.

Try This
<script type="text/javascript">
$(document).ready(function () {
$("#TextboxId").autocomplete({
source: function (request, response) {
$.ajax({
url: "URL",
type: "POST",
dataType: "json",
data: { ids: idstopass },
success: function (retrieveddata) {
alert(retrieveddata);
var dData = JSON.parse(retrieveddata);
alert(dData.Name);
},
error: function (request, status, error) {
console.log("Error! " + request.responseText);
}
})
},
});
})
</script>
