在模式弹出按钮单击事件，一个网格视图中没有发射 [英] Button click event on modal popup, inside a grid-view not firing
问题描述
我在遇到以下问题。
场景：
我有一个结合数据数列的ASP网格。最后一列已被转换为一个模板字段。在此模板场是与连接到它一个模式弹出扩展器的按钮。这个领域里面隐藏的是一个模式弹出。这种模式弹出来添加新帐户。它包含两个文本框，下拉列表和按钮（添加和取消）。当添加点击模态的新帐户在code后面插入后，应该关闭。
The scenario: I have a asp grid with a few columns that bind to data. The last column has been converted to a template-field. In this template-field is a button with a modal popup extender attached to it. Hidden inside this field is a modal popup. This modal popup is used to add a new account. it contains 2 text boxes, drop down lists and buttons("Add" and "Cancel"). When "add" is clicked the modal should close after the inserting of the new account in the code behind.
问题：
我得到显示和加载下拉从缓存列表，没有问题的弹出窗口。我如何获得按钮点击事件在$ C $丙火的后面。我已经使用执行_doPostBack（'btnAddAcc'，''）的JavaScript函数尝试，但它一直返回错误JavaScript错误：预期的对象。我收集后，在谷歌约1个小时，这是因为btnAddAcc'没有发现，因为它实际上是网格视图单元格中，不能直接访问。使用页面方法和Ajax调用是不得已而为之的公司有对这种并有严格的政策，只有一堆手续后，允许这个。
The Problem: I get the popup to display and load the Drop down lists from the cache, without problem. How do I get the button click event to fire in the code behind. I've tried using a JavaScript function that performs a _doPostBack('btnAddAcc','') but it keeps returning the error "JavaScript error: Object expected". I gathered after about 1 hour on Google that it is because "btnAddAcc' is not found because it is actually within the grid-view cell and can't be directly accessed. Using page methods and ajax calls is a last resort as the company has a strict policy against this and only allowes this after a bunch of paperwork.
在code：

我打开弹出这个JavaScript函数：
I open the popup with this JavaScript function:
function showPopUp(p) {
var Popup = document.getElementById(p);
Popup.style.visibility = "visible";
Popup.style.display = "";
}
点击btnAddAcc时，此功能：
The function when btnAddAcc is clicked:
function addAccount() {
_doPostBack('btnAddAcc', '');
};
背后的功能code
The code behind function
Protected Sub btnAddAcc_Click(sender As Object, e As System.EventArgs)
'Code for inserting new account goes here
End Sub
感谢您事先的任何帮助和建议。

推荐答案
我找到了答案，最终。我不得不使用gridview.RowCommand事件。它处理GridView的单元格内的所有按钮相关的事件。
I found the answer eventually. I had to use the gridview.RowCommand event. It handles all button related events inside a cell of a gridview.
看一看MSDN文档。这里需要解释一下最该命令的。
Have a look at the msdn documentation. It should explain most of this command.
