C#

function nummins(evt,obj) {
            var vlr;
            var vlr = (window.event) ? event.keyCode : evt.which;
            if ((vlr >= 48 && vlr <= 57) || vlr == 8) {
       if(obj.value.length==2)
             {
               obj.value=obj.value+"."; 
return true;
          }

        else(obj.value.length>5)
             {
                
return false;
          }
            }
            else {
                alert("Time should be a Numeric Value");
                return false;
            }
        }

Try this,

C#

function isNumberLimit(evt, ctrlName, leftLimit, rightLimit) {

    var str = ctrlName.value;
    var caretPos = doGetCaretPosition(ctrlName);
    var decPos = str.indexOf('.');
    var intNum = (str.indexOf('.') != -1) ? str.substring(0, str.indexOf('.')).length : str.length;
    var decNum = str.substring(str.indexOf('.') + 1, str.length).length;
    var charCode = (evt.which) ? evt.which : event.keyCode;
    if (charCode == 8) {
        return true;
    }
    else if ((charCode < 48 && charCode != 46) || charCode > 57) {
        return false;
    }
    else if (str.length >= leftLimit && str.indexOf(".") == -1 && charCode != 46 && charCode != 08) {
        return false;
    }

    else if (charCode == 46 && (str.indexOf(".") != -1)) {
        return false;
    }
    else if (decPos != -1) {
        if (caretPos > decPos) {
            if (decNum >= rightLimit) {
                return false;
            }
            else {
                return true;
            }
        }
        else {
            if (intNum >= leftLimit) {
                return false;
            }
            else {
                return true;
            }
        }
    }
    else {
        return true;
    }

}

And call function like,

<asp:textbox id="TextBox1" runat="server" maxlength="5" onkeypress="return isNumberLimit(event,this,2,2)" xmlns:asp="#unknown"></asp:textbox>
