我正在使用ASP.Net TreeView控件,並使用C#動態加載Treeview;ASP.Net Treeview控件不在Web服務器上的iFrame中顯示文檔

利用iFrame,文檔顯示在iFrame中 - 基於TreeNode選擇;

在我的電腦上一切正常,並且文檔從網絡中的公共驅動器正確顯示;

但是,在將ASP.Net Web應用程序發佈到Web服務器後,遇到了問題;

在Web服務器上重新創建帶有文檔的公共文件夾 - 我的期望是該過程將以與我的PC上的過程相同的方式工作;

ASP.Net TreeView的人口工作正常;但是,如果選擇了TreeView節點 - 從TreeView中選擇的文檔不會顯示;

代碼片段如下;預先感謝任何見解!最好的問候 - 羅布

private void BuildTree() 
{ 
DirectoryInfo rootDir = new DirectoryInfo(Server.MapPath("./Customers/Associated Food Stores/")); 
TreeNode rootNode = new TreeNode(rootDir.Name, rootDir.FullName); 
      TreeView1.Nodes.Add(rootNode); 

      //begin recursively traversing the directory structure 
      TraverseTree(rootDir, rootNode); 
     } 

private void TraverseTree(DirectoryInfo currentDir, TreeNode currentNode) 
     { 
      //loop through each sub-directory in the current one 
      foreach (DirectoryInfo dir in currentDir.GetDirectories()) 
      { 
       //create node and add to the tree view 
       TreeNode node = new TreeNode(dir.Name, dir.FullName); 
       currentNode.ChildNodes.Add(node); 

       foreach (System.IO.FileInfo f in dir.GetFiles("*.*")) 
       { 
        TreeNode nodeFile = new TreeNode(f.Name, f.FullName); 
        currentNode.ChildNodes.Add(nodeFile); 
       } 

       //recursively call same method to go down the next level of the tree 
       TraverseTree(dir, node); 
      } 

      TreeView1.CollapseAll(); 

      //TreeView1.NodeIndent = 15; 

     } 

     protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e) 
     { 
      //this.Label1.Text = "Selected Node changed to: " + this.TreeView1.SelectedNode.Text; 
      var src = this.TreeView1.SelectedValue; 

      if (this.TreeView1.SelectedValue.EndsWith("pdf")) 
      { 
       myPDF.Attributes["src"] = src; 
       myPDF.Visible = true; 

       btnClose.Visible = true; 
      } 
     }

看起來這行:

var src = this.TreeView1.SelectedValue; 

將始終保持物理路徑的文件,因爲你的方式添加值:

TreeNode nodeFile = new TreeNode(f.Name, f.FullName); 

因此,當您將src屬性設置爲iframe時,應將src映射到託管應用程序的虛擬目錄
