问两个弱弱的关于XsltListViewWebPart和ContentEditorWebPart的问题
我在一个WebPart中加了如下代码，把当前网站上所有LIST用XsltListViewWebPart显示出来
                    XsltListViewWebPart xlvWebPart = null;
                    foreach (SPList currList in currWeb.Lists)
                    {
                        if (currList.BaseType.CompareTo(SPBaseType.GenericList) == 0)
                        {
                            xlvWebPart = new XsltListViewWebPart();
                            xlvWebPart.ListId = currList.ID;
                            xlvWebPart.Title = currList.Title;
                            this.LayoutPanelMain.Controls.Add(xlvWebPart);
                        }
                    }
不过遇到一个问题，就是显示出的LIST 下面没有toolbar 显示 add new item链接，请问怎么让他显示，
还有个问题怎么用C#代码给ContentEditorWebPart里增加html内容
[解决办法]
1. 将某个list作为web part添加到某个页面应该用如下代码：

2. ContentEditorWebPart只能写HTML和Javascript, CSS等前台代码的。
[解决办法]
参考这段代码:

if (myItem.Name.ToUpper() == "DEFAULT.ASPX")
{
SPLimitedWebPartManager webPartCollection = myItem.File.GetLimitedWebPartManager(PersonalizationScope.Shared);
PublishingPage myPage = PublishingPage.GetPublishingPage(myItem);
 myPage.CheckIn("if checked out");
 myPage.CheckOut();
int u = webPartCollection.WebParts.Count; 
for(int i=0;i<=u;i++){
Microsoft.SharePoint.WebPartPages.WebPart webpt = (Microsoft.SharePoint.WebPartPages.WebPart)webPartCollection.WebParts;
if (webpt.GetType().ToString() == "Microsoft.SharePoint.WebPartPages.ContentEditorWebPart"){
//Create an XmlElement to hold the value of the Content property.
ContentEditorWebPart ceWebPart = new ContentEditorWebPart();
 
// Create an XmlElement to hold the value of the Content property.
XmlDocument xmlDoc = new XmlDocument();
 XmlElement xmlElement = xmlDoc.CreateElement("Content");
 xmlElement.InnerText = ((
ContentEditorWebPart)webpt).Content.InnerText.ToString();  
 
xmlElement.InnerText = xmlElement.InnerText.ToString().Replace(
"hotmail", "Yahoo");
//Set the Content property to the XmlElement. 
ceWebPart.Content = xmlElement;
((
ContentEditorWebPart)webpt).Content = ceWebPart.Content;webPartCollection.Web.AllowUnsafeUpdates = true;
webPartCollection.SaveChanges(webpt);
 webPartCollection.Web.AllowUnsafeUpdates = false;
} 
}
 myPage.Update();
myPage.CheckIn("");
if (myPage.ListItem.ParentList.EnableModeration)
 {
 myPage.ListItem.File.Approve(""); 
} 
}
