关闭modalpopup时刷新页面

Question

我有2个Ajax模态弹出窗口（我省略了大部分代码），当我关闭它们时，我想重新绑定包含数据网格的页面。 我试图尝试捕获回发控件并仅在该控件被列出时重新绑定，因为该页面上还有其他回发控件，但它不起作用。 任何帮助将不胜感激...

                {
                    // Looking for the control ID
                    // string sControl = Page.FindControl(CtlName).ClientID;
                    if ((CtlName.Contains("dg")) || (CtlName.Contains("imgCancel")) || (CtlName.Contains("imgCancelNV")))

        }

               BindData();
            }
