Hi

You can write this JavaScript Function nd then call it on Textbox event

JavaScript

<script type="text/javascript" language = "javascript">
 function Check(e)
    {
     var unicaode = e.charcode ? e.charcode : e.KeyCode 
 if (!((unicaode >= 48 && unicaode <= 57) || (unicaode = 64) || (unicaode >= 65 && unicaode <= 90) || (unicaode = 95) || (unicaode = 46) || (unicaode >= 97 && unicaode <= 122) ))
           {
     alert('Invalid character');
         return false;
         }
       else 
       {
         return true;
       }
     
    }
 </script>

And call it on TextBox event

ASP.NET

<asp:textbox id="txtInput" runat="server" style="position :absolute " onkeypress="return Check(event)" xmlns:asp="#unknown"></asp:textbox>

Thank You
