为SharePoint添加Event Receiver

为列表类型绑定Event Receiver可以通过添加一个feature, 并在feature中添加一个receiver element来完成.

具体详见SharePoint中的EventReceiver 之二 绑定Event Receiver到列表类型或列表实例.

 

除了可以为列表类型添加event receiver以外, MOSS 2007还可以在如下的三种对象的实例上添加Event Receiver.

• SPList
• SPContentType
• SPWeb

为他们添加event receiver可以通过SharePoint Object Model来完成, 核心代码为以下的函数调用.

SPEventReceiverDefinitionCollection.Add 

 

有一个免费的为sharepoint中的列表, contenttype, 站点添加event receiver的工具, 非常好用. 点击这里下载可执行文件和源代码.

 

添加的关键代码片段如下:

if (node.Tag is SPList)

{

    SPList list = (SPList)node.Tag;

    list.EventReceivers.Add

        ((SPEventReceiverType)Enum.Parse(typeof(SPEventReceiverType), comboBoxEventType.Text),

         textBoxAssemlby.Text, comboBoxClasses.Text);

    list.Update();

    flag = true;

}

if (node.Tag is SPContentType)

{

    SPContentType ct = (SPContentType)node.Tag;

    ct.EventReceivers.Add

        ((SPEventReceiverType)Enum.Parse(typeof(SPEventReceiverType), comboBoxEventType.Text),

         textBoxAssemlby.Text, comboBoxClasses.Text);

    ct.Update();

    flag = true;

}

if (node.Tag is SPWeb)

{

    SPWeb w = (SPWeb)node.Tag;

    w.EventReceivers.Add

        ((SPEventReceiverType)Enum.Parse(typeof(SPEventReceiverType), comboBoxEventType.Text),

         textBoxAssemlby.Text, comboBoxClasses.Text);

    w.Update();

    flag = true;

}

 

移出的关键代码如下:

TreeNode node = treeViewItems.SelectedNode;

SPEventReceiverDefinition er = (SPEventReceiverDefinition)node.Tag;

if (MessageBox.Show("Are you sure you want to remove this event handler?", "Event Handler Explorer", 

MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)

{

    er.Delete();
