有时候页面是要放一个PeopleEditor,然后赋值给item。当然最开始的时候想法应该是超级简单,直接把控件的value赋值给item就完事了。结果根本就不是那么一回事。

网上有人提供了方法,写了一大堆,很复杂,两眼没看懂,又感觉怎么不像自己要的。没办法,还是要自己弄一下。

不过还是要承认借鉴了网上通用的方法,只是在SharePoint2010有点变化。

页面加控件:

<SharePoint:PeopleEditor ID="people" runat="server" selectionset="User" MultiSelect="false" />

只选一个人的PeopleEditor控件

下面的方法是拿控件里的值。和网上sharepoint2007版本的有点不同,在string DisplayName行

public static string GetPeopleEditorValue(PeopleEditor objPeopleEditor)
        {
            string strResult = string.Empty;
            ArrayList list = objPeopleEditor.ResolvedEntities;
            
            foreach (Microsoft.SharePoint.WebControls.PickerEntity p in list)
            {
                string userId = p.EntityData["SPUserID"].ToString();
                string DisplayName = p.DisplayText.ToString();
                strResult += userId + ";#" + DisplayName;
                strResult += ",";
            }
            return strResult;
        }

赋值:

SPContext.Current.ListItem["人"] = GetPeopleEditorValue(people);

如果PeopleEdit里面没有选人,则是空值,ListItem["人"]就是空值,不会报什么错误的。

----------

注意,上面的方法不是很好,当这个用户从来没有登录到SharePont上,那么这个方法是会报错误的。这种情况发生在测试阶段就会暴露出来。

要用下面的方法

 public string GetPersonInfo(Control control, string ffID)
{
        string strReturn = "";
        if (control is PeopleEditor)
        {
            if (((PeopleEditor)control).Parent.Parent.Parent.ID == ffID)
            {
                PeopleEditor peopleEditor = ((PeopleEditor)control);
                foreach (PickerEntity pe in peopleEditor.ResolvedEntities)
                {
                    string principalType = pe.EntityData["PrincipalType"].ToString();
                    if (principalType == "User" || principalType == "SecurityGroup")
                    {
                        strReturn = pe.Key;
                        break;
                    }
                }
            }
        }
        else
        {
            foreach (Control c in control.Controls)
            {
                strReturn = GetPersonInfo(c, ffID);
                if (strReturn != "")
                {
                    break;
                }
            }
        }
        return strReturn;
 }

有取值就要有赋值

public void SetDefaultPerson(Control control, string ffID, string userLoginName)
 {
            string strflag = "";
            if (control is PeopleEditor)
            {
                if (((PeopleEditor)control).Parent.Parent.Parent.ID == ffID)
                {
                    if ((((PeopleEditor)control).ResolvedEntities.Count < 1))
                    {
                        PickerEntity entity = new PickerEntity();
                        entity.Key = userLoginName;

                        System.Collections.ArrayList entityArrayList = new
                        System.Collections.ArrayList();
                        entityArrayList.Add(entity);

                        ((PeopleEditor)control).UpdateEntities(entityArrayList);
                        strflag = "TaskOver";
                    }
                }
            }
            else
            {
                foreach (Control c in control.Controls)
                {
                    SetDefaultPerson(c, ffID, userLoginName);
                    if (strflag != "")
                    {
                        break;
                    }
                }
            }
}
