我有一个包含两组控件的页面,每个集合的ValidationGroup设置不同,但如果我尝试正确填写一个表单,则另一个表单的验证器会停止触发Click事件。
我注意到它的行为通常是客户端,但按钮会导致回发事件,服务器验证程序似乎没有遵守验证组。我不确定我做错了什么。当然,内置的验证器都支持服务器端的验证组吗?
以下是一个完整的独立示例:
<%@ Page Language="C#" %>
<script runat="server">
protected void SubmitButton_Click(object sender, EventArgs e)
{
Page.Validate();
if (Page.IsValid) label.Text = "OK: " + ((Button)sender).ID.ToString();
}
</script>
<!DOCTYPE html>
<html>
<head runat="server">
<style>
body { font-family: sans-serif;}
.warning { color: red;}
</style>
</head>
<body>
<form id="f1" runat="server">
<h1>Validator Test</h1>
<asp:Label ID="label" runat="server" Font-Bold="true" ForeColor="Green" EnableViewState="false" /><br />
<div style="width:40%; float:left; height:200px; border:1px solid #eee; padding:15px; margin:5px;">
<h2>Left Form:</h2>
Email: <asp:TextBox ID="leftBox" runat="server" Columns="20" MaxLength="80" Width="160px" ValidationGroup="LEFT" />
<asp:RequiredFieldValidator ID="left2" runat="server" ControlToValidate="leftBox"
ErrorMessage="You must enter a value." ValidationGroup="LEFT">*</asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="rev8" runat="server" ControlToValidate="leftBox" ValidationGroup="LEFT" Text="*"
ErrorMessage="Email address format is invalid." ValidationExpression="^[\.\-\w]+@([\w\-]+\.)+\w+$" />
<asp:Button ID="LeftSubmitButton" runat="server" Text="Save Left" OnClick="SubmitButton_Click" ValidationGroup="LEFT" />
<asp:ValidationSummary ID="LeftValidationSummary" runat="server" HeaderText="Error:" ValidationGroup="LEFT" CssClass="warning" />
</div>
<div style="width:40%; float:left; height:200px; border:1px solid #eee; padding:15px; margin:5px;">
<h2>Right Form:</h2>
Email: <asp:TextBox ID="rightBox" runat="server" Columns="20" MaxLength="80" Width="160px" ValidationGroup="RIGHT" />
<asp:RequiredFieldValidator ID="rfv9" runat="server" ControlToValidate="rightBox"
ErrorMessage="You must enter an value." ValidationGroup="RIGHT">*</asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="rev10" runat="server" ControlToValidate="rightBox" ValidationGroup="RIGHT" Text="*"
ErrorMessage="Email address format is invalid." ValidationExpression="^[\.\-\w]+@([\w\-]+\.)+\w+$" />
<asp:Button ID="RightSubmitButton" runat="server" Text="Save Right" OnClick="SubmitButton_Click" ValidationGroup="RIGHT" />

删除显式的完整页面验证 - 即此行:
Page.Validate();
它忽略了验证组。
您会注意到Page.Validate()
也覆盖了允许您指定确切验证组的内容 - 例如Page.Validate("RIGHT")
。这是出于框架目的; Web表单基础结构已经为您调用了正确的Validate()
,因此无需显式调用它。
