SharePoint 2013 如何使用TaxonomyWebTaggingControl 控件

浏览数：68 / 时间：2015年06月09日

　　在该文章中，我将介绍如何使用TaxonomyWebTaggingControl控件，首先我相信您已经在SharePoint Managed Metadata Service里定义Term Sets,如果没有，请先定义您的Term Sets（可以参考该文章how to create metadata column)，该控件能帮助我们显示/设置各种Terms。

　　其次我们需要了解Managed Metadata的结构，请看以下图，您可以清晰地看到每一个结构（Term Store -> Group -> Term Set -> Terms)，接下来我们进入主题，该如何使用TaxonomyWebTaggingControl 控件绑定这些数据呢，在该案例中我们绑定Product Type Group的所有数据。

　　根据以下步骤：

在我们的设计页面中定义注册Microsoft.SharePoint.Taxonomy控件

<%@ Register TagPrefix="Taxonomy" Namespace="Microsoft.SharePoint.Taxonomy" Assembly="Microsoft.SharePoint.Taxonomy, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

　　2. 在内容部分添加TaxonomyWebTaggingControl控件

<Taxonomy:TaxonomyWebTaggingControl ID="twtc_productType" runat="server"></Taxonomy:TaxonomyWebTaggingControl>

　　3. 在后台绑定数据(从Managed Metadata Service中获取Group的数据)

 1 using Microsoft.SharePoint;
 2 using Microsoft.SharePoint.Taxonomy;
 3 
 4 /// <summary>
 5 /// TaxonomyWebTaggingControl Bind
 6 /// </summary>
 7 /// <param name="productTypeControl">TaxonomyWebTaggingControl Control</param>
 8 public static void ProductTypeBind(TaxonomyWebTaggingControl productTypeControl)
 9         {
10             // Open the site
11             using (SPSite site = new SPSite(SPContext.Current.Web.Url))
12             {
13                 using (SPWeb web = site.OpenWeb())
14                 {
15                     TaxonomySession session = new TaxonomySession(site);
16                     // Get the Term Store node from Managed Metadata Service
17                     TermStore termStore = null;
18                     if (session.TermStores != null && session.TermStores.Count > 0)
19                    {
20                       termStore = session.TermStores["Managed Metadata Service"]; //if you a custom meta service you should change name.
21                     }
22                     if (termStore != null)
23                     {
24                         //Guid anchorId = new Guid();
25                         Group group = termStore.Groups["Product Type"]; // Get the Group node from Managed Metadata Service
26                         productTypeControl.SspId.Add(termStore.Id); // do it for all termsets
27                         foreach (TermSet item in group.TermSets)
28                         {
29                             productTypeControl.TermSetId.Add(item.Id); // Add the Term
30                             /*  This could be achieved by setting AnchorId property for TaxonomyWebTaggingControl control that allows to specify ID of parent Term for any valid value in control.
31                             foreach (Term term in item.Terms)
32                             {
33                                 if (term.Name == ManagedMetadataType.TermName)
34                                 {
35                                     anchorId = term.Id;
36                                     break;
37                                 }
38                             } */ 
39                         }
40 
41                         //productTypeControl.AnchorId = anchorId;
42                         productTypeControl.GroupId = group.Id;
43                         productTypeControl.IsAddTerms = false;
44                     }
45                 }
46             }
47         }
