推荐答案

u无需为此使用蒙版编辑..您可以使用过滤器文本框扩展程序

参见示例

u have their no need to use masked edit for this..instead of this you can use filter textbox extender

see example

<div>
        <asp:scriptmanager id="ScriptManager1" runat="server" >
        </asp:scriptmanager>
        <asp:textbox id="TextBox1" runat="server" textmode="Password" xmlns:asp="#unknown"></asp:textbox>
        <asp:filteredtextboxextender id="TextBox1_FilteredTextBoxExtender">
            runat="server" Enabled="True" TargetControlID="TextBox1" 
            ValidChars="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789">
        </asp:filteredtextboxextender>
    </div>

在上面的示例中，我使用了ajax filtertexbox扩展器来根据需要添加值..
现在你的问题就解决了


注意-

1. 将文本框"文本模式更改为密码
2.像我一样将过滤器扩展器的过滤器类型属性设置为自定义..

如果有任何疑问答复

谢谢

in the above example i have used ajax filtertexbox extender to filer the value as u want..
now your problem is solve


Note-

1. Change the Textbox textmode to Password
2. set the Filter type property of filter extender to custom as i have done..

<asp:RegularExpressionValidator 
ID="validator1" 
ControlToValidate="txt1"
ValidationExpression="XXX" 
Text = "Input Not Valid"
runat="server" />

XXX = ^(\ w *)

XXX = ^(\w*)
