如何在SPGridView中设置超链接字段的navigationUrl

Question

我想要获取根网站下的所有网站集并使用SPGridView显示它们。在SPGridView中，我使用HyperlinkField显示名称，网址并为每个网站创建。 我的问题是我无法将该网站的URL附加到HyperlinkField。任何想法如何可以在代码中完成？

[ToolboxItemAttribute(false)] 
public class SPGridViewDemo : WebPart 
{ 
    private SPGridView grid; 
    private ObjectDataSource gridDS; 

    public DataTable SelectData() 
    { 
     DataTable dataSource = new DataTable(); 

     dataSource.Columns.Add("Name"); 
     dataSource.Columns.Add("Created"); 
     dataSource.Columns.Add("Url"); 

     SPWebApplication webApplication = SPContext.Current.Site.WebApplication; 
     SPSiteCollection siteCollections = webApplication.Sites; 
     SPSite currentSite = SPContext.Current.Site; 

     foreach (SPSite siteCollection in siteCollections) 
      { 
       dataSource.Rows.Add(siteCollection.RootWeb.Title, siteCollection.RootWeb.Created, siteCollection.RootWeb.Url); 
      } 

     return dataSource; 
    } 


    protected sealed override void Render(HtmlTextWriter writer) 
    { 
     BoundField column = new BoundField(); 
     HyperLinkField hyplink = new HyperLinkField(); 

     hyplink.DataTextField = "Name"; 
     hyplink.NavigateUrl = "Url"; 
     hyplink.SortExpression = "Name"; 
     hyplink.HeaderText = "Workspaces"; 
     grid.Columns.Add(hyplink); 

     column = new BoundField(); 
     column.DataField = "Created"; 
     column.SortExpression = "Created"; 
     column.HeaderText = "Created"; 
     grid.Columns.Add(column); 

     column = new BoundField(); 
     column.DataField = "Url"; 
     column.SortExpression = "Url"; 
     column.HeaderText = "Url"; 
     grid.Columns.Add(column); 

     grid.Sort("Name",System.Web.UI.WebControls.SortDirection.Descending); 
     grid.DataBind(); 

     base.Render(writer); 
    } 

    protected sealed override void CreateChildControls() 
    { 
     const string gridId = "grid"; 
     const string dataSourceId = "gridDS"; 

     gridDS = new ObjectDataSource(); 
     gridDS.ID = dataSourceId; 
     gridDS.SelectMethod = "SelectData"; 
     gridDS.TypeName = this.GetType().AssemblyQualifiedName; 
     gridDS.ObjectCreating += new ObjectDataSourceObjectEventHandler(gridDS_ObjectCreating); 
     this.Controls.Add(gridDS); 

     grid = new SPGridView(); 
     grid.ID = gridId; 
     grid.DataSourceID = gridDS.ID; 
     grid.AutoGenerateColumns = false; 

     // Paging 
     grid.AllowPaging = true; 
     grid.PageSize = 5; 

     // Sorting 
     grid.AllowSorting = true; 

     this.Controls.Add(grid); 

     SPGridViewPager pager = new SPGridViewPager(); 
     pager.GridViewId = grid.ID; 

     this.Controls.Add(pager); 
    } 

    private void gridDS_ObjectCreating(object sender, ObjectDataSourceEventArgs e) 
    { 
     e.ObjectInstance = this; 
    }

您应该使用HyperLinkField.DataNavigateUrlFields Property代替：

HyperLinkField hyplink = new HyperLinkField(); 

hyplink.DataTextField = "Name"; 
hyplink.DataNavigateUrlFields = new string[] { "Url" }; 
hyplink.SortExpression = "Name"; 
hyplink.HeaderText = "Workspaces"; 
grid.Columns.Add(hyplink); 

的HyperLinkField.NavigateUrl Property用于呈现静态URL：

使用NavigateUrl属性来指定网址导航到当一个超链接在HyperLinkField对象中单击。设置此属性时，每个超链接共享相同的导航URL。
