如何在GridView中获取复选框ID [英] How to get the checkbox id in the gridview

问题描述

在我的应用程序中，我使用带有更新面板的gridview控件.在那个gridview中，我使用了1个Checkbox控件和三个下拉菜单.对于复选框，我具有checkedchanged事件，对于所有三个下拉菜单，我具有选定的索引更改事件.选中此复选框后，事件将触发并且页面正在刷新.下拉控件也是如此.我的问题是我想更改选定的索引，并且应该在不刷新页面的情况下发生选中的更改事件.我已经尝试为该控件提供异步回发触发器，但是它没有用.谁能帮我解决这个问题.这是代码:

Hi,

In my application I am using the gridview control with update panel. In that gridview I am using 1 Checkbox control and three dropdown. For check box I am having the checkedchanged event and for all the three dropdown I am having the selected index change event . When the check box is checked the event is firing and the page is refreshing. And the same happens for the dropdown control. My problem is I want to make the selected index change and checked change event should happen without refreshing the page. I have tried giving the asynchronous post back trigger for that controls, but it not worked. Can anyone please help me to solve this problem. Here is the Code:

<table align="center" class="css_MainTable">
                                <tr>
      <td align="center" colspan="2">

推荐答案

尝试做:

AutoPostBack="false"

否则调用javascript函数并返回false

else call a javascript function and return false

在您需要的事件上调用更新面板的更新方法

call the update method of update panel on your required events

在您的事件上调用更新面板的更新方法必需的事件

或

设置autopostback ="False"

call the update method of update panel on your required events

OR

Set autopostback="False"
