刷新或添加從另一個ascx控制ascx控制

Question

我正在一個asp.net項目，我有一個主要的ascx控制由兩個RadSpliters分開。在加載main.ascx時，應用程序正在加載兩個其他控件，即control1.ascx和control2.ascx。在control1中我有一個樹視圖，並在樹視圖的選定節點上，我想重新加載control2.ascx。有沒有辦法做到這一點。下面我粘貼我正在使用的代碼，但不工作。有任何幫助或建議嗎？

public partial class Control1: System.Web.UI.UserControl 
{ 
     protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e) 
    { 
     BrowseProject b = new BrowseProject(); 
     b.load(); 
    } 




public partial class MainControl : System.Web.UI.UserControl 
    { 
      public void load() 
     { 
       Control codeEditor = Page.LoadControl("Control2.ascx"); 
      PlaceHolder4.Controls.Clear(); 
      PlaceHolder4.ID = "PlaceHolder4"; 
      PlaceHolder4.Controls.Add(codeEditor); 

     }

public interface IReload{ 
    public void reload(); 
} 

public partial class Control2: System.Web.UI.UserControl, IReload 
{ 

} 

public partial class Control1: System.Web.UI.UserControl 
{ 
    IReload _r; 

    public IReload setReload 
    { 
     set { _r = value; } 
    } 


    protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e) 
    { 
     BrowseProject b = new BrowseProject(); 
     b.load(); 
     if(_r != null){ 
      _r.reload(); 
     } 
} 

public partial class MainControl : System.Web.UI.UserControl 
{ 
     public void load() 
    { 
     Control codeEditor = Page.LoadControl("Control2.ascx"); 
     PlaceHolder4.Controls.Clear(); 
     PlaceHolder4.ID = "PlaceHolder4"; 
     PlaceHolder4.Controls.Add(codeEditor); 

     c.setReload(codeEditor); 
    }
