禁用Update Panel外部的控制 [英] Disable control outside Update Panel

问题描述

嗨朋友们，

我有一个只有Timer控件的UpdatePanel。

在Timer的OnTick事件中，我正在检查某些条件。如果条件为真，我想禁用UpdatePanel外面的按钮。

你能帮我吗？



谢谢，

推荐答案

嗨朋友们，

我尝试了类似下面的东西，但它确实有效。

与你分享。

Hi Friends,
I tried something like below and it worked.
Sharing with you.

<script language="javascript" type="text/javascript">
                Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
                Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler);

                function BeginRequestHandler(sender, args) {
                    elem = args.get_postBackElement();
                }

                function EndRequestHandler(sender, args) {
// tmrTimer is my timer control inside update panel
// btnCloseModules is button control outside update panel
                    if (elem.id == "ctl00_MainContentPlaceHolder_tmrTimer")
                        document.getElementById("ctl00_MainContentPlaceHolder_btnCloseModules").disabled = true;
                }

工作.. :)



谢谢，

It works .. :)

另一个简单的方法。

Another simple approach.

System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, typeof(Page), "Script", "document.getElementById('" + your_button.ClientID + "').disabled='true';", true);
