and Save it.
Now It should be working!

Clear, Remove, Delete SharePoint 2010 people editor Value Post Back Event PeopleEditor picker = PeopleSelector; picker.Accounts.Clear(); picker.Entities.Clear(); picker.ResolvedEntities.Clear(); --------------------------------------------------------------------------------------------- This code will trigger every time the page refreshes; this means, if you need to trigger it on button click, ensure you call a clearPicker function from below on OnClientClick event of your button or means similar to this.
<script type="text/javascript">
// this registers clearPicker to run every time the page reloads
_spBodyOnLoadFunctionNames.push("clearPicker");
// this is the function that clears the picker and helper variables
function clearPicker() {
var control;
var arr = document.getElementsByTagName("div");
for (var i = 0; i < arr.length; i++) {
if (arr[i].id.indexOf("upLevelDiv") > 0)
{ control = arr[i]; }
}
control.innerHTML = '';
arr = document.getElementsByTagName("input");
for (var i = 0; i < arr.length; i++) {
if (arr[i].name.indexOf("hiddenSpanData") > 0)
{ control = arr[i]; }
}
control.value = '';
}
</script>
That’s it; the upLevelDiv and hiddenSpanData now contains no resolved values and the people editor appears cleared.
public static SPUser GetSPUser(SPListItem item, string key)
{
SPFieldUser field = item.Fields[key] as SPFieldUser;

if (fieldValue != null)
return fieldValue.User;
