Question

我似乎无法在调试时激活我的EventReceiver。我在GAC进行调试。

我不是sharepoint或SP Objects的专家。

当用户更改我创建的下拉框中的值时，我想做点什么

Dropdownbox

    [ChoiceField(Name = F.Adgang, DisplayName = "Adgang", Required = true, DefaultValue = "Alle", Choices = new string[] { "Alle", "Kun indehavere" })]
    public bool Adgang
    {
        get { return G(); }
        set { S(value); }
    }

Model.cs

public class Model : SPFeatureReceiver
{

    public override void FeatureActivated(SPFeatureReceiverProperties properties)
    {
        SPSite site = properties.Feature.Parent as SPSite;

        site.RootWeb.CreateContentType<CourseAndEvent>();
        site.RootWeb.CreateContentType<DanboligNewsPage>();

        using (SPWeb web = site.OpenWeb())
        {
            var list = web.Lists[""];
            var e = list.EventReceivers.Add(Guid.NewGuid());

            e.Name = "test_All";
            e.Type = SPEventReceiverType.ItemAdded | SPEventReceiverType.ItemDeleted | SPEventReceiverType.ItemDeleting;
            e.Assembly = typeof(NewsReceiver).Assembly.FullName;
            e.Class = typeof(NewsReceiver).FullName;
            e.SequenceNumber = 10;
            e.Update();

            list.Update();
            web.Update();
        }


    }

}

NewsReceiver.cs

class NewsReceiver : SPItemEventReceiver
{
    public override void ItemAdded(SPItemEventProperties properties)
    {
        base.ItemAdded(properties);

        SPListItem item = properties.ListItem;
        string folderName = item["Name"].ToString();
        string folderUrl = SPUtility.ConcatUrls(SPUtility.ConcatUrls(item.Web.Url, item.ParentList.RootFolder.Url), folderName);

        SPFile file = item.File;
    }

    public override void ItemDeleting(SPItemEventProperties properties)
    {
        base.ItemDeleting(properties);
    }

    public override void ItemDeleted(SPItemEventProperties properties)
    {
        base.ItemDeleted(properties);
    }
}

任何人都可以告诉我为什么在调试时没有任何ItemEvents没有触发，？

Answer 1

我假设您将调试器附加到w3wp.exe。你确定你有合适的吗？另外，您是否已查看有关调试事件接收器的this MSDN page？（陈旧但相关）

您是否确保将事件接收器附加到列表或包含它的站点？请参阅here。

Answer 2

尝试在代码中的某处设置以下代码行。它将启动调试器：

System.Diagnostics.Debugger.Launch();

MSDN

但如果你没有将EventReceiver正确地附加到你想要的对象上，它将无济于事。我还希望用SharePoint Manager检查一下，看看EventReceivers是否正确连接/注册。

SPItemEventReceiver在调试时不会触发
