推荐答案

您的父用户控件需要部分刷新.触发子窗口的updatpanel是否也控制父页面"文本框? (这样，如果触发了更新面板，那么文本框的值也会被刷新吗?)

此外，如果该场景类似于本文，则可能会有所帮助:
在子窗口关闭时通过AJAX(ASP.NET 2.0)对父页面进行部分更新-有条件地 [ ^ ]

You parent usercontrol needs a partial refresh. Is the updatpanel that triggers the child window, controls the Parent page textbox too? (such that if update panel is triggered then the textbox value will also get refreshed?)

Further, if the scenario is something similar to this article then it might help:
