在vb.net中动态创建表时出错 [英] Error in creating a table dynamically in vb.net
问题描述
我使用AutoEventWireup =" true"创建了一个简单的表格。 表单有一个面板和一个按钮。

我相信所有这些都非常简单明了，但是当我点击按钮时，会立即生成以下错误：
mscorlib.dll中出现'System.Threading.ThreadAbortException'类型的第一次机会异常
方法参数必须括在括号中。

有没有人对这些错误有解释？ 我已经设置了所有调试选项，但没有任何反应，页面刷新没有发生任何事故。 错误只出现在即时窗口中。
请根据需要重定向到其他论坛。
谢谢

形成此KB，根本原因是 Response.Redirect 方法调用，并且可以将
false 值作为第二个参数传递给Response.Redirect方法，如KB所示。
&NBSP;
I created a simple table with AutoEventWireup="true". The form has a panel and a button.
<%@ Page Title="Home Page" Language="vb" AutoEventWireup="true" CodeBehind="Default.aspx.vb" Inherits="WebApplication1._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
Protected Sub Page_Init(ByVal sender As Object, ByVal e As EventArgs)
ViewData()
End Sub
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<table align="center" width="88%">
<tr>
<td align="center">
<asp:panel ID="Panel2" runat="server" >
<asp:Button ID="Button2" runat="server" Text="Return" Height="40px" onclick="Button2_Click"
Width="60px" Font-Size="X-Small" BorderStyle="Solid"
visible="true"
BorderWidth="3px" BorderColor="#CC3300" />
</asp:panel>
</td>
</tr>
</table>
</form>
</body>
</html>
The code behind looks like this:
Public Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
Protected Sub ViewData()
Dim tb3 As New Table()
Dim tc1 As New TableCell
tc1.Text = "test this"
Dim tc2 As New TableCell
tc2.Text = "Gentlemen"
Dim tr1 As New TableRow
tr1.Controls.Add(tc1)
tr1.Controls.Add(tc2)
tb3.Rows.Add(tr1)
Panel2.Controls.Add(tb3)
Button2.Visible = True
End Sub
Protected Sub Button2_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button2.Click
Response.Redirect("default.aspx")
End Sub
End Class
I believe all very simple and straightforward, however when I click the button the following errors are generated in the immediate window:
A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll
Method arguments must be enclosed in parentheses.
A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll
Method arguments must be enclosed in parentheses.
Does anyone have an explanation for these errors? I have set break all on debugging choices but nothing happens and the page refreshes without incident. The errors only appear in the immediate window.
Please redirect to a different forum as needed.
Thanks

Form this KB, the root cause is the Response.Redirect method call in your Button2_Click method, and you can pass the false value as the second parameter to the Response.Redirect method as the KB said.
