文本框textchanged事件 [英] textbox textchanged event

问题描述

我有一个asp.net项目
在这个项目中，我有一个带有textchanged事件的TextBox和AutoPostBack = true
以及压延扩展器及其目标控件，位于先前的文本框

我有时需要在后面的代码中更改压延机的选定日期
但这会使回发以在页面加载后执行文本框的textchanged事件

我问在更改

i have an asp.net project
in this project i have a TextBox with a textchanged event and AutoPostBack = true
and a calender extender and the target control of it the previous textbox

i sometimes need to change the selected date of the calender extender in code behind
but this make a postback to execute the textchanged event of the textbox after the page loads

i''m asking if there is a way to prevent the post back when changing the selected date of the calender extender in code behind

推荐答案

后面的代码中，更改日历扩展器的选定日期时是否有办法防止回发. ..您的问题将得到解决.

Just add Update Panel....your problem will be solved.

将小东西放在一边，简而言之，您需要将Grid放在Udpate面板中以启用部分渲染:.您去了:

UpdatePanel控件概述 [ UpdatePanel控件 [ UpdatePanel类 [

Keeping small things aside, in short, you need to put your Grid in an Udpate Panel to enable partial rendering:. Here you go:
