TemplateField 按钮导致 GridView 无效回发 [英] TemplateField button causing GridView Invalid Postback
问题描述
好的，所以我在 gridview 中有一个模板字段，其中只包含一个简单的按钮...
Ok, so I've got a template field in a gridview that contains just a simple button...
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Administration.aspx.cs"
Inherits="Administration" %>
<%@ Register TagPrefix="ajaxToolkit" Namespace="AjaxControlToolkit" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Keywords Administration</title>
</head>
<body class="popupbody">
<form id="form1" runat="server">
<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" EnablePartialRendering="true" CombineScripts="false"></ajaxToolkit:ToolkitScriptManager>
<asp:Label ID="AddLabel" runat="server">Add a Keyword</asp:Label>
<br />
<asp:TextBox ID="AddTextBox" runat="server" />
<asp:Button ID="AddButton" Text="Add" runat="server" OnClick="AddKeyword_Click" />
<asp:GridView ID="KeywordsGridView" AllowPaging="false" AutoGenerateColumns="false" BackColor="white"
GridLines="None" HeaderStyle-CssClass="Table_Header" RowStyle-CssClass="Table_Style"
OnRowDataBound="RowBound" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Button runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="References" SortExpression="References" HeaderText="Total References" />
<asp:BoundField DataField="Keyword" SortExpression="Keyword" HeaderText="Keyword" />
</Columns>
</asp:GridView>
</form>
</body>
</html>
每当我点击按钮时，我都会收到错误...
Whenever I click the button I get the error...
Invalid postback or callback argument. Event validation is enabled using
<pages enableEventValidation="true"/> in configuration or <%@ Page
EnableEventValidation="true" %> in a page. For security purposes, this feature
verifies that arguments to postback or callback events originate from the server
control that originally rendered them. If the data is valid and expected, use the
ClientScriptManager.RegisterForEventValidation method in order to register the
postback or callback data for validation.
我发现了大量引用此问题的文章，例如，包括一些关于 SO 的文章...
I've found a decent amount of articles referencing this issue, including a couple on SO, for example...
还有……
我可能只是误会了，但据我所知，他们并没有真正帮助我.如何在不设置 enableEventValidation="false" 的情况下让它消失?
I might just be misunderstanding, but as far as I can tell they don't really help me. How do I get this to go away without setting enableEventValidation="false"?
EDIT 发布了我页面的所有代码.
EDIT Posted all the code for my page.
