SharePoint中的EventReceiver 之四 為Content Type編寫Event Handler

在前面的部分, 我們建立了CompanyItemEventReceiver類來在Company names中使用大寫來保持資料完整性. 作為這個Event Receiver的系列的最後部分, 我們現在希望展現一下如何把event receiver類中的event handler綁定到Company這個Content Types上. 這是通過在content type的definition中使用一個inner XmlDocument節點, 下面進行了舉例. 你可以看到, 每一個event handler都必須被單獨地使用相同地資訊來綁定.

 

<ContentType ID="0x0100E71A2716C18B4e96A9B0461156806FFA" Name="Company" >  <!-- FieldRefs element omitted for clarity -->  <!-- event handlers added to content type using XmlDocument element -->  <XmlDocuments>    <XmlDocument NamespaceURI="http://schemas.microsoft.com/sharepoint/events">      <spe:Receivers xmlns:spe="http://schemas.microsoft.com/sharepoint/events">        <spe:Receiver>          <spe:Name>ItemAddedReceiver</spe:Name>          <spe:Type>ItemAdded</spe:Type>          <spe:Assembly>LitwareTypes, [full 4-part assembly name] </spe:Assembly>          <spe:Class>LitwareTypes.CompanyItemEventReceiver</spe:Class>        </spe:Receiver>        <spe:Receiver>          <spe:Name>ItemUpdatedReceiver</spe:Name>          <spe:Type>ItemUpdated</spe:Type>          <spe:Assembly>LitwareTypes, [full 4-part assembly name] </spe:Assembly>          <spe:Class>LitwareTypes.CompanyItemEventReceiver</spe:Class>        </spe:Receiver>      </spe:Receivers>    </XmlDocument>  </XmlDocuments></ContentType>
