Hi Animesh,

Use String method replaceAll() to remove the special characters

String str;
str = str.replaceAll('[^a-z^A-z^0-9]', '');

Hi Animesh,

If you want to check while user type then you need to take help of javascript
  
<apex:inputText value="{!Coupon}" onkeyup="return isValidDate(this);"/>
<script>
function isValidDate(f){ 
    var re =/^[\d\/\.-]+$/;
   if (!re.test(f.value)) { 
//    alert("called");
//if you need to add a value instead that can also be done here
return false;
   }
 }
</script>

Hi Animesh,

Please find following code.
  
<script type="text/javascript">
        var specialKeys = new Array();
        specialKeys.push(8); //Backspace
        specialKeys.push(9); //Tab
        specialKeys.push(46); //Delete
        specialKeys.push(36); //Home
        specialKeys.push(35); //End
        specialKeys.push(37); //Left
        specialKeys.push(39); //Right
        function IsAlphaNumeric(e) {
            var keyCode = e.keyCode == 0 ? e.charCode : e.keyCode;
            var ret = ((keyCode >= 48 && keyCode <= 57) || (keyCode >= 65 && keyCode <= 90) || (keyCode >= 97 && keyCode <= 122) || (specialKeys.indexOf(e.keyCode) != -1 && e.charCode != e.keyCode));
            
            return ret;
        }
    </script>
  
<apex:inputText value="{!Coupon}" onkeypress="return IsAlphaNumeric(event);" ondrop="return false;" onpaste="return false;"/>

Thanks,
Himanshu

Hi Himanshu,

Thank you very much for the solution, but ondrop and onpaste does not work with <apex:inputText/>. 
Now, special character are not coming when typing from keyboard, but if I paste special charater, it is still appearing. Is there any solution on it?
