SharePoint PeopleEditor 控件的使用
最近一段时间，项目用到了PoopleEditor控件，下面的资料都是从网上收集过来并做一些整理简单的用法
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Register Tagprefix="Utilities" Namespace="Microsoft.SharePoint.Utilities" Assembly="Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Import Namespace="Microsoft.SharePoint" %>
<SharePoint:PeopleEditor id="PeopleEditor1" runat="server"
SelectionSet="User"
ValidatorEnabled="true"
AllowEmpty = "false"
MultiSelect = "true"
/>
上面是SharePoint 2007的用法，一般要注册控件
SelectionSet---是可以先择的范围，一般可以是组，人，及Ad的安全组等
ValidatorEnable----如果设置为True，其会自动验证，当刷新的时候
AllowsEmpty--允许为空的意思
获取用户的选择值
ArrayList list = PeopleEditor1.ResolvedEntities ;
//获取id和显示名称
foreach (Microsoft.SharePoint.WebControls.PickerEntity p in list)
{
string userId = p.EntityData["SPUserID"].ToString();
string DisplayName = p.EntityData["DisplayName"].ToString();
}
//获取帐号
ArrayList selectedAccoutList = PeopleEditor1.Accounts;
string selectedAccouts2 = PeopleEditor1.CommaSeparatedAccounts;
设置控件的值
PeopleEditor1.CommaSeparatedAccounts = @"JYSERVER\spsadmin,JYSERVER\administrator";
如果是允许多个值，那么可以把放到一个集合里面，如下
string[] user = userPicker.CommaSeparatedAccounts.Split(new string[] { "," }, StringSplitOptions.None)
SharePoint 2010可以引用以下DLL文件
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
--Note：其实在SharePoint 2010 里面可以引用07上段的注册，在开发中一样可以用！
较复杂的用法
下面是一个可以允许组，安全组，人的实例，允许多选！
<SharePoint:PeopleEditor ID="pplApprovers" width="300px" SelectionSet="User,DL,SecGroup,SPGroup" MultiSelect="true" AllowTypeIn="true" IsValid="true" runat="server" />
设置值
private ArrayList approversArray;
private SPFieldUserValueCollection approversCollection;
approversCollection = (SPFieldUserValueCollection)item[“Approvers”];
PickerEntity entity = new PickerEntity();
approversArray = new ArrayList();
foreach (SPFieldUserValue spFieldUserValue in approversCollection)
{
entity = new PickerEntity();
entity.Key = spFieldUserValue.LookupValue;
entity = pplApprovers.ValidateEntity(entity);
approversArray.Add(entity);
}
pplApprovers.UpdateEntities(approversArray);
取值
approversArray = pplApprovers.ResolvedEntities;
//Use the following code to save the data back to the list item:
approversCollection = new SPFieldUserValueCollection();
SPUser user;
SPGroup group;
foreach (PickerEntity entity in approversArray)
{
if (entity.EntityData["PrincipalType"].ToString() == "SharePointGroup")
{
group = web.SiteGroups;
approversCollection.Add(new SPFieldUserValue(web, group.ID, group.LoginName));
}
else
{
//handles SecurityGroup, Distribution List and User
user = web.EnsureUser(entity.Key);
approversCollection.Add(new SPFieldUserValue(web, user.ID, user.LoginName));
}
}
item[“Approvers”] = approversCollection;
UI设置方面
一般来说，如果其允许多个选择的时候，其会很比较宽，同时其会比较大，而且选择的按钮也是显示在右下角，当我们用在查询的时候，就会显示得很不好看，所以我们要限制其高度等其他方面让其显示得漂亮一点。下面是我用到的一个可以多重选择的，显示在一行的实例。
<td style="width:400px; text-align:left; height:28px; line-height:28px;">
<SharePoint:PeopleEditor ID="pdName"SelectionSet="User,SPGroup" MultiSelect="true"runat="server" Rows="1" Width="100%" PlaceButtonsUnderEntityEditor="false"
/>
</td>
其中
PlaceButtonsUnderEntityEditor="false"让浏览按钮设置右边
Rows="1" 意思只高度只有一行。
一般来说可以设置其BorderColor="Gray" BorderWidth="1“ 这样子还是挺好看的！
最好设置ValidatorEnabled="true"
上面是我用到查询出报表中，其可以参考上面的复杂用法取值，如我项目中这样做的
List<string> userlist = new List<string>();
#region 得到用户列表
SPWeb web = SPContext.Current.Web;
ArrayList approversArray = pdName.ResolvedEntities;
foreach (PickerEntity entity in approversArray)
{
if (entity.EntityData["PrincipalType"].ToString() == "SharePointGroup")
{
SPGroup group = web.SiteGroups;
grouplist.Add(group);
}
else
{
SPUser user = web.EnsureUser(entity.Key);
userlist.Add(user.LoginName);
}
}
foreach (SPGroup g in grouplist)
{
SPUserCollection users = g.Users;
foreach (SPUser u in users)
{
if (!userlist.Contains(u.LoginName))
{
userlist.Add(u.LoginName);
}
}
}
#endregion
其他的如Secroup和DL 暂时不知道怎么取，可以较复杂的那种 可以取出来，等用到的时候再填充！
