【转】解决CustomValidator控件不能验证控件值为空的问题（asp.net1.1测试环境）
不要指定CustomValidator 控件的ControlToValidate就行了,这样在提交的时候回进行验证
代码如下:
---------------------------------
<%@ Page Language="C#" AutoEventWireup="True" %>
<html>
<head>
</head>
<body>
<form runat="server" id="Form1" >
<asp:TextBox id="Text1"
runat="server" />
<asp:CustomValidator id="CustomValidator1"
ClientValidationFunction="ClientValidate"
Display="Static"
ErrorMessage="不能为空!"
ForeColor="green"
Font-Name="verdana"
Font-Size="10pt"
runat="server"/>
<br/>
<asp:Button id="Button1"
Text="Validate"
runat="server"/>
</form>
</body>
</html>
<script language="javascript">
<!--
function ClientValidate(sender, args)
{
var txtvalue = document.getElementById("TextBox1");
if(txtvalue .value.length<=0)
{
args.IsValid = false;
}else{
args.IsValid = true;
}
}
// -->
</script>
