extaspnet框架的问题
页面如下
<body>
<form id="form1" runat="server">
<div>
<ext:PageManager ID="PageManager1" runat="server" />
<ext:Window ID="Window1" runat="server"
Title="系统后台登陆"
IsModal="false" EnableClose="false"
Width="350px">
<Items>
<ext:SimpleForm ID="SimpleForm1"
runat="server" ShowBorder="false"
BodyPadding="10px"
EnableBackgroundColor="true"
ShowHeader="false">
<Items>
<ext:TextBox ID="tbxUserName" Label="用户名："
Required="true" runat="server"
RequiredMessage="用户名不允许为空"
Text="ASPNETDemo">
</ext:TextBox>
<ext:TextBox ID="tbxPassword"
Label="密&nbsp;&nbsp;&nbsp;码："
TextMode="Password" Required="true"
runat="server" RequiredMessage="密码不允许为空" Text="888888">
</ext:TextBox>
<ext:TextBox ID="tbxCaptcha" Label="验证码："
Required="true" runat="server"
RequiredMessage="验证码不允许为空">
</ext:TextBox>
</Items>
</ext:SimpleForm>
</Items>
</ext:Window>
</div>
</form>
</body>
然后运行下，就老是提示：未将对象引用设置到对象的实例。
[NullReferenceException: 未将对象引用设置到对象的实例。]
