javascript for validating numeric with two decimal points

As I have stated in one of my previous posts , here is the javascript for validating texbox which accepts only numbers and two decimal points. The number will be automatically formatted when it loose the focus. There are plenty of third party tools that provide numeric text boxes that can achieve the similar tasks. I hope this will give some consolation for those who can't afford buying them.

<script type="text/javascript" language="javascript">
    function format(n, sep, decimals) {
        if (n == '') {
            document.getElementById('ctl00_ContentPlaceHolder1_txtBuyAmt').value = "0.00";        
            return 0.00;
        }
        if (isNaN(replaceSubstring(n, ',', ''))) {
            document.getElementById('ctl00_ContentPlaceHolder1_txtBuyAmt').value = "0.00";
            return 0.00;
        }
       
        var buyAmt = replaceSubstring(document.getElementById('ctl00_ContentPlaceHolder1_txtBuyAmt').value, ',', '');
        n = parseFloat(buyAmt);
        sep = sep || "."; // Default to period as decimal separator
        decimals = decimals || 2; // Default to 2 decimals

        return n.toLocaleString().split(sep)[0]
        + sep
        + n.toFixed(decimals).split(sep)[1];
    }
    function replaceSubstring(inSource, inToReplace, inReplaceWith) {

        var outString = inSource;
        while (true) {
            var idx = outString.indexOf(inToReplace);
            if (idx == -1) {
                break;
            }
            outString = outString.substring(0, idx) + inReplaceWith +
      outString.substring(idx + inToReplace.length);
        }
        return outString;

    }
   

    function validateOnlyNumber(evt) {
        var theEvent = evt || window.event;
        var key = theEvent.keyCode || theEvent.which;
        key = String.fromCharCode(key);

        if (key == '.') {
            if (document.getElementById('ctl00_ContentPlaceHolder1_txtBuyAmt').value.indexOf(key) > 0) {
                theEvent.returnValue = false;
                if (theEvent.preventDefault) theEvent.preventDefault();

            }
        }

        if (document.getElementById('ctl00_ContentPlaceHolder1_txtBuyAmt').value == '' && key != '.') {
            theEvent.returnValue = false;
            if (theEvent.preventDefault) theEvent.preventDefault();
        }
        var regex = /[0-9]|\./;
        if (!regex.test(key)) {
            theEvent.returnValue = false;
            if (theEvent.preventDefault) theEvent.preventDefault();
        }
    }

    function checkNumbers() {

        var ValidChars = /[0-9]|\./;

        var pasteData = window.clipboardData.getData("Text");

        if (ValidChars.test(pasteData))

            return true;

        else {

            return false;

        }

    }
</script>

call the javascipts as follows
 <asp:TextBox ID="txtBuyAmt" runat="server" Width="200px"  onpaste="return checkNumbers()"   onblur="this.value=format(this.value);"  onkeypress='validateOnlyNumber(event)' >0.00</asp:TextBox>

Note: Here I have placed the text box inside a  contentplaceholder.

javascript for validating numeric text

Following javascript can be used to validate numerical values for a textbox. This validates  numbers without decimal points. If you want to validate decimals and thousand separators as well , you'll have to change the regex and call another javascript onblur event to validate the thousand separator and decimal point. I will post the javascript for this soon.

<script type="text/javascript">

 function validateOnlyNumber(evt) {
        var theEvent = evt || window.event;
        var key = theEvent.keyCode || theEvent.which;
        key = String.fromCharCode(key);
        var regex = /^\s*\d+\s*$/;
        if (!regex.test(key)) {
            theEvent.returnValue = false;
            if (theEvent.preventDefault) theEvent.preventDefault();
        }
    }

        function checkNumbers() {
            var ValidChars = /^\s*\d+\s*$/;
            var pasteData = window.clipboardData.getData("Text");


            if (ValidChars.test(pasteData))
                return true;
            else {
             
                return false;
            }
        }

        
 </script>


Call the functions as follows

<asp:TextBox ID="txtSearch" runat="server"   onpaste="return checkNumbers()"  onkeypress='validateOnlyNumber(event)'></asp:TextBox>

Dealing with DOM events

There are some events that will help us to achieve some tasks that are not directly visible through standard events. These are DHTML events and they are invisible in intellisense or properties window of the IDE simply because ASP.NET doesn't know them, and  they will be rendered to the client. There are number of DOM events as such and you can find more details in the MSDN site.

$(function() {
$('input[id$=txtBoxName]').click(function() {

Working with button OnClick() and OnClientClick()

When we want to check some client side validation on a buttons' click  OnClientClick() comes to your assistance. But it seems that using OnClick() and OnClientClick() events at the same time bit tricky.

I have tried following ways, but none of them worked..!!

OnClientClick="return ValidateFunciton();" OnClientClick="if(ValidateFunciton()) return true;"
OnClientClick="ValidateFunciton();"

But following worked for me

<asp:Button ID="btnSearch" runat="server" Text="Search"  
OnClick="btbSearch_Click" 

OnClientClick="if (!ValidateFunciton()) { return false;};" />

opensource rich text editor for asp.net

"CKEditor" is the best WYSYWIG editor that can be used for asp.net. For more details check here.

In addition AjaxToolkit also provides a HtmlEditorExtender which takes advantage of HTML5 and supports IE 6 and later and other leading browsers. Check more details here.

Edit
. Refer this article for an excellent example of using HtmlEditorExtender. You might face some configuration errors (i.e. Unrecognized element 'sanitizer'.    ) when setting up this control.

Change web.config as follows to overcome this error.
  <configSections>
 <sectionGroup name="system.web">
      <section name="sanitizer" requirePermission="false"
               type="AjaxControlToolkit.Sanitizer.ProviderSanitizerSection, AjaxControlToolkit" />
    </sectionGroup>
  </configSections>

The first entry in <system.web> section shoud be chaged as follows
<trust level="Full" />
  <sanitizer defaultProvider="HtmlAgilityPackSanitizerProvider">
      <providers>
        <add name="HtmlAgilityPackSanitizerProvider" type="AjaxControlToolkit.Sanitizer.HtmlAgilityPackSanitizerProvider"></add>
      </providers>
    </sanitizer>
You'll be need ed to add a reference to all three assemblies contained in the folder: SanitizerProviders.dll,and HtmlSanitizationLibrary.dll which can be found in the AjaxControlToolkit source.

IIS 7.x asp.net 4.0 deployment

If  you have tried to deploy an asp.net 4.0 web application in IIS 7.x you would have come up with few configuration errors. Follow these steps to overcome these errors

 1)  To register .Net in IIS, open up an admin command prompt and navigate to the .NET 4 framework folder (C:\Windows\Microsoft.NET\Framework\v4.{version}). If you're on a 64 bit machine go to the Framework64 folder instead of the Framework folder. Then run aspnet_regiis -i in there  (you will need admin permission on windows 7 to do this)

 2)  Use the "ISAPI and CGI Restrictions" IIS feature to allow your CGI program to run.  You can either add the individual program or simply "Allow unspecified CGI modules".

send mms from sql server (only within Sri Lanka)

Most of us know that we  can send MMS messages  using gmail. For the sake of completion I ll list down the basic steps to achieve it.

1)  Compose a new mail. In the to box type your mobile number (i.e. 009477xxxxxxx@mms.dialog.lk for Dialog, 009471xxxxxxx@mms.mobitel.lk for Mobitel). I haven't tried this with the other service providers. 

2) Type in you message and send it as you are sending a normal email.

I have taken this to a one more step further by using this concept to send mms messages from SQL Server dbmail. Follow these steps

1) Create a mail profile for your gmail account using Database Mail wizard. Specify your maill account setting as follows.

2) Call the created profile inside your stored procedure ass follows.

EXEC msdb.dbo.sp_send_dbmail
    @profile_name = 'sendmail',
    @recipients = '009477xxxxxxx@mms.dialog.lk',
    @body = 'Congrats for sending first MMS..!!.',
    @subject = 'Test MMS' ;

It will take some time to deliver sms  to the recipient. Please note that the recipients phone must support MMS for reading this message.  You can use this method to send a simple SMS without being bothered about buying a SMS gateway. 



Note: If you receive the "gmail smtp error 5.7.0" message when sending mail, try changing SMTP from smtp.gmail.com to smtp.googlemail.com 

Cheers

asp.net crystal reports issues

If you are going to do reporting with crystal reports  you will face some problems in configuring it.  Follow these steps to minimize the fuss. It took me almost a day to figure these out ...!!

1) Create a Asp.Net Reports website.
2) Add other configuration settings to web.config file. (i.e connection strings, httpmodules...etc)
3) If you are getting the error "Sys.Application' is null or not an object",  Edit theC:\Windows\Microsoft.NET\Framework\v4.0.30319\ASP.NETClientFiles\crystalreportviewers14\js\crviewer\crv.js  as follows
 insted of
if(typeof(Sys)!=='undefined') {

    Sys.Application.notifyScriptLoaded();
}
use
if(typeof(Sys) !== 'undefined' && typeof(Sys.Application) !== 'undefined') {
Sys.Application.notifyScriptLoaded();
}


Note: You can download Crystal Reports runtime for  Visual Studio 2010 from

Edit:
 Crystal reports seems to have some incompatibilities with Microsoft Ajax framework. In fact if you put a crystal report viewer inside an update panel it will prompt you various JavaScript errors at run time. So you have find other ways to overcome this such as using third party tools. I am contended with Microsoft Reports which very well suited for my requirements...!!!
