Solution 2

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

see example

ASP.NET

<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>

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..

if any queries reply

thanks

Solution 3

C#

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

XXX = ^(\w*)$
that matches char (with accent too), numbers and the underscore

XXX = ^(a-zA-Z0-9)*$
that matches char (with no accent), numbers

Note :
XXX = ^(a-zA-Z0-9){m,n}$

m = minimum lenght
n = maximum lenght
