刷新或添加来自其他ascx控件的ascx控件

Question

我在一个asp .net项目上工作，我有一个主ascx控件，它被两个RadSpliters分割。在加载main.ascx时，应用程序会加载另外两个控件，control1.ascx和control2.ascx。在control1中，我有一个树视图，在树视图的选定节点上，我想重新加载control2.ascx。有没有办法做到这一点。下面我粘贴了我用来做这件事的代码，但不起作用。有什么帮助或建议吗？

  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);
    }
