Work with people picker.

<SharePoint:PeopleEditor ID="pplSendTo" runat="server" CssClass="ms-inputuserfield" Width="250px" SelectionSet="User,SPGroup" />

* Selection set is used to mention whether people editor should accept user and spgroup.

Get values from people editor

Users = "";
UserID = "";
if (pplSendTo.ResolvedEntities.Count > 0 && pplSendTo.IsValid)
                        {
                            int usercount = pplSendTo.ResolvedEntities.Count;
                            for (int i = 0; i < usercount; i++)
                            {
                                PickerEntity peEntity = pplSendTo.ResolvedEntities[i] as PickerEntity;
                                SPUser ouser = SPContext.Current.Web.EnsureUser(peEntity.Key);
                                if (Users == "" && UserID == "")
                                {
                                    Users = Convert.ToString(ouser);
                                    UserID = Convert.ToString(ouser.ID);
                                }
                                else
                                {
                                    Users = Users + "," + Convert.ToString(ouser);
                                    UserID = UserID + "," + Convert.ToString(ouser.ID);
                                }
                            }
                        }

This will help you to get single user as well as multiple users.


Bind values into people editor.

ArrayList arrList = new ArrayList();

_pickerEntity = new PickerEntity(); // PickerEntitiy use using Microsoft.SharePoint.WebControls

SPFieldUserValueCollection UserCollection = new SPFieldUserValueCollection();

if (!string.IsNullOrEmpty(Convert.ToString(dr2["SendToUsersName"])))

{

pplSendTo.Visible = true;

SPUser ouser = null;

string[] user = Convert.ToString(dr2["SendToUsersName"]).Split(',');

SPContext.Current.Web.AllowUnsafeUpdates = true;

SPGroupCollection groupColl = SPContext.Current.Web.Groups;

for (int k = 0; k < user.Length; k++)

{

Boolean value = false;

_pickerEntity = new PickerEntity();

foreach (SPGroup ogroup in groupColl)

{

if (Convert.ToString(ogroup) == user[k])

{

value = true;

_pickerEntity.Key = ogroup.LoginName;

arrList.Add(_pickerEntity);

break;

}

}

if (!value)

{

ouser = SPContext.Current.Web.SiteUsers[user[k]];

_pickerEntity.Key = ouser.LoginName;

arrList.Add(_pickerEntity);

}

}

pplSendTo.UpdateEntities(arrList);

this will help you to bind both users and groups into a people picker
