Question

我正在使用以下代码以编程方式将网页部件添加到网页中，但是我有一个问题，在页面回传后，网页部分是在页面上看不到，我需要刷新页面以获取Web部件可见。

SPSite site = new SPSite("http://syngdcds0032:23547");
site.AllowUnsafeUpdates = true;   
SPWeb web = site.OpenWeb();
web.AllowUnsafeUpdates = true;  
SPList list = web.Lists["Assets"];
SPView setView = list.Views["VVV"];

// Instantiate the web part
ListViewWebPart wp = new ListViewWebPart();
wp.ZoneID = "Left";
wp.ListName = list.ID.ToString("B").ToUpper();
//wp.ViewGuid = list.DefaultView.ID.ToString("B").ToUpper();
wp.ViewGuid = setView.ID.ToString("B").ToUpper();
// Get the web part collection
SPWebPartCollection coll =
    web.GetWebPartCollection("http://syngdcds0032:23547/Pages/AssetSearch1.aspx",
    Storage.Shared);

// Add the web part
coll.Add(wp);

一些建议

使用SPContext.Current.Site，SPContext.Current.Web而不是创建这些对象的新实例 - 从内存使用的角度来看，这是“昂贵的”

尝试使用LimitedWebpartManager类（http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.webpartpages.splimitedwebpartmanager_methods.aspx）将webpart添加到页面。在这种情况下，您不必在每次调用中将webpart添加到页面中，您必须在页面的生命周期中执行一次。代码看起来像这样

    Dim op As WebPartPages.SPLimitedWebPartManager
    op = oWeb.GetLimitedWebPartManager("default.aspx", Web.UI.WebControls.WebParts.PersonalizationScope.Shared)
    oWP = New WebPartPages.ListViewWebPart
    oWP.ListName = oWeb.Lists("Workflow tasks").ID.ToString("B").ToUpper()
    oWP.AllowClose = False
    oWP.AllowHide = False
    oWP.AllowMinimize = False
    oWP.AllowZoneChange = True
    oWP.ExportMode = Web.UI.WebControls.WebParts.WebPartExportMode.All
    oWP.Title = "Darba uzdevumi"
    oWP.ChromeType = Web.UI.WebControls.WebParts.PartChromeType.TitleOnly
    oWP.ViewGuid = oWeb.Lists("Workflow tasks").Views("All Items").ID.ToString("B").ToUpper()
    oWP.ZoneID = "Right"
    op.AddWebPart(oWP, "Right", 1)
