进度条不使用回发触发器 [英] Progress bar not working with postback trigger

问题描述

我想在点击按钮时显示进度条，但它没有工作，因为它有回发触发器。如果我删除帖子后退触发进度条正在显示但我必须把回发触发器显示报告（rdlc）。



谢谢，

推荐答案

之前我遇到过同样的问题。

你需要在体内添加这个脚本。

有两个函数，如InitializeRequest和EndRequest，它们将在更新面板分别开始更新和结束更新时调用。

I faced the same problem before.
You need to add this script inside body.
There are two functions like "InitializeRequest" and "EndRequest", which will be called when update panel begin updating and end updating respectively.

<script language="javascript" type="text/javascript">
                <!--
        var prm = Sys.WebForms.PageRequestManager.getInstance();
        function CancelAsyncPostBack() {
            if (prm.get_isInAsyncPostBack()) {
                prm.abortPostBack();
            }
        }
        prm.add_initializeRequest(InitializeRequest);
        prm.add_endRequest(EndRequest);
        var postBackElement;
        function InitializeRequest(sender, args) {
            if (prm.get_isInAsyncPostBack()) {
                args.set_cancel(true);
            }
            postBackElement = args.get_postBackElement();
            if (postBackElement.id == 'btnEdit') {
                // Loading the image which has display none property inside the  UpdateProgress control...(code is provided below)

（ #loadingImage）。css（' display'，' block'）;

// 减少包含整个页面控件的总表的不透明度...

("#loadingImage").css('display', 'block'); // Reducing the opacity of the total table which contains the whole page controls...

（' ＃totalTable'）。 css（' opacity'，' < span class =code-string> 0.20'）;

('#totalTable').css('opacity', '0.20');
