I have a SharePoint List who has the column of type Person or Group.

In my webpart solution I am trying to use Caml Query to get the Data of the List based on Department column. Each Department is assigned with Multiple Number of Persons.

I want to fill a Dropdown to Select Person from Dropdown and the Dropdown must be filled with the data returned based on Department

I've gone through this but couldn't find any solution of using my own list in SharePoint People Picker Control

Following is the Image of my List:

    public partial class VisualWebPart1UserControl : UserControl
        protected void Page_Load(object sender, EventArgs e)
            using (SPSite site=new SPSite("http://sp/sites/jerry"))
                SPWeb web = site.OpenWeb();

                SPListItem item = list.GetItemById(6);
                SPFieldUserValueCollection reviewers = (SPFieldUserValueCollection)item["Reviewers"];
                List<PickerEntity> reviewersEntity = new List<PickerEntity>();
                foreach (SPFieldUserValue spuserval in reviewers)

                    SPUser userToassign = spuserval.User;
