問題的Ajax和RadTreeView

Question

大家： 我有包含從Telerik的RadTreeView內部ModalPopupExtender，先前的控制在運行時加載的用戶控制：

DashBoardDesignerCell tempCell = LoadControl("~/UserControls/DashBoardDesignerControls/DashboardDesignerCell.ascx") as DashBoardDesignerCell; 

當SelectedNodeChanged發生ModalPopupExtender消失。

這是用戶CONTRL的完整代碼：

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="DashBoardDesignerCell.ascx.cs" 
    Inherits="RightBI.UserControls.DashBoardDesignerControls.DashBoardDesignerCell" %> 

<%@ Register Src="~/UserControls/PresentationControls/SelectPresentationControl.ascx" TagPrefix="rightbicontrols" TagName="selectpresentationcontrol" %>

有沒有什麼想法？？？

當您選擇樹視圖節點時，您是否通過任何方式執行回發或ajax請求？這可能會導致模式彈出式擴展程序關閉。爲什麼不使用Telerik Ajax窗口來比較結果？另外我假設你在初始化或加載頁面時動態地加載用戶控件，並在添加用戶控件之前清除容器的Controls集合。
