我创建了一个webpart,然后我创建了第二个.cs页面,它将呈现自定义html。它基本上只是一个显示图像的简单页面。但是在第二个.cs页面中,我需要访问Web部件中的自定义设置。如果单击指向辅助页面的链接,如何在主Web部件中访问自定义工具窗格设置?
第二页是从VS 2010生成的,位于layouts文件夹中,如下所示:
public partial class GetFile : LayoutsPageBase
{
我想我必须从网络部分继承一些内容才能做到这一点,但真的不确定如何?

您可以通过阅读页面上的Web部件集及其属性,使用SPLimitedWebPartManager
类访问Web部件属性,如下所示,
var web = SPContext.Current.Web;
var currentPageURL = "//URL of the page on which the Web part is present";
var page = web.GetFile(currentPageURL);
using (SPLimitedWebPartManager webPartManager = page.GetLimitedWebPartManager(PersonalizationScope.Shared))
{
try
{
var webPartList = from System.Web.UI.WebControls.WebParts.WebPart webPart in webPartManager.WebParts select webPart;
foreach (System.Web.UI.WebControls.WebParts.WebPart webPart in webPartList.ToList())
{
if (webPart.Title.ToLower() == "//Name of the web part for which you want to read the properties")
{
PropertyInfo[] wptProperties = webPart.GetType().GetProperties(BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance);
foreach (PropertyInfo property in wptProperties)
{
if (property.Name == "//Name of the web property which you want to get")
{
// Following code updates the web part property, you can also read it
property.SetValue(webPart, "value to be set", null);
webPartManager.SaveChanges(webPart);
break;
}
}
}
}
Response.Redirect(currentPageURL);
}
finally
{
webPartManager.Web.Dispose();
}
}
