【问题描述】：
除了删除行时没有发生回发之外，一切正常。我在 OnRowDeleting 和 OnRowDataBound 中放置了一个调试器中断 唯一的区别是您没有 Ajax 更新面板和脚本管理器。下面是 Gridview 的图像。当我点击确定按钮时没有任何反应。
以下是我在新页面上的代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm3.aspx.cs" Inherits="SidePanelGridViewTest.WebForm3" %>

<div id ="mydialog" style="display:none" runat="server">
<h2>Do you really want to delete?</h2>
</div>
<script>
function myclick(mycontrolid) {
var mydiv = $('#mydialog');
mydiv.dialog({
autoOpen: false, modal: true, title: 'Delete?', width: '25%',
position: { my: 'top', at: 'top+150' },
buttons: {
'ok': function () {
vbtns = '#' + mycontrolid.replace('imgbtnDelete', 'MyDelete');
$(vbtns).click();
},
'cancel': function () {
mydiv.dialog('close');
}
}
});
mydiv.dialog('open');
}
</script>
</form>
</body>
</html>
下面是gridview的图片：
当我单击删除弹出窗口中的“确定”按钮时。回发不会发生。我在 OnRowDeleting 和 OnRowDataBound 上都有调试器中断。当我开始运行代码时，调试器在 OnRowDataBound 上中断，但单击弹出窗口上的“确定”按钮不会导致回发。
下面是代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace SidePanelGridViewTest
{
public partial class WebForm3 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void OnRowDeleting(object sender, GridViewDeleteEventArgs e)
{
int index = Convert.ToInt32(e.RowIndex);
}
protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
string x = "Test";
}
}
}
