Hi
jagpalbashati,
Open your own Chat Provider
Find method below. I think you set nickName=loginName; in the below method. so the display name will same as the loginname.
public override bool GetUserInfo(string loginName, ref string nickName, ref bool isAdmin)
{
}
You can change the section to the name you want to show, like
nickName="jagpalbashati";
all user will display as jagpalbashati.
Regards,
Ken
