Function you are looking for

Fore more detail read article : Enhanced Textbox Control[^]

C#

function IntegerAndDecimal(e,obj,isDecimal)
{
    if ([e.keyCode||e.which]==8) //this is to allow backspace
    return true;

    if ([e.keyCode||e.which]==46) //this is to allow decimal point
    {
      if(isDecimal=='true')
      {
        var val = obj.value;
        if(val.indexOf(".") > -1)
        {
            e.returnValue = false;
            return false;
        }
        return true;
      }
      else
      {
        e.returnValue = false;
        return false;
      }
    }

    if ([e.keyCode||e.which] < 48 || [e.keyCode||e.which] > 57)
    e.preventDefault? e.preventDefault() : e.returnValue = false;
}

Hi,

This Script can be used to validate your form for numeric values. The Numeric TextBox allows only numbers and accepts one decimal Point.

XML

<script language=javascript>
function keyCheck(eventObj, obj)
{
    var keyCode

    // Check For Browser Type
    if (document.all){
        keyCode=eventObj.keyCode
    }
    else{
        keyCode=eventObj.which
    }

    var str=obj.value

    if(keyCode==46){
        if (str.indexOf(".")>0){
            return false
        }
    }

    if((keyCode<48 || keyCode >58)   &&   (keyCode != 46)){ // Allow only integers and decimal points
        return false
    }

    return true
}
</script>

<asp:TextBox ID="txtNumeric" runat="server" onkeypress = "return keyCheck(event, this);"

onpaste = "return false;"></asp:TextBox>

Solution 4

You can also create a mask for the textbox to accept int values and alphabets only.
