How to Insert page break during printing

This code is helpful when you want insert page breaks between the page. You have to divide your content in divs.

<script language="javascript" type="text/javascript">
function PrintPageBreakAfter( ){
divs = document.getElementsByTagName(arguments[0]);
for (var i=0; i < divs.length-1; i++ ) {
div = divs[i];
if(div.id!=''){
div.style.pageBreakAfter = (arguments[1]) ? "always":"";
}
}
window.print();
}
</script>

<body onload="JavaScript:togglePageBreakAfter('DIV', true, true);" topmargin="0">

<div id="div1">
Content
</div>

<div id="div2">
Content
</div>

Ajaxtootlkit Color Picker: _colorRegex undefined

I was using the colorpicker as per ajaxtoolkit site directives in my project.

but still I was getting one javascript error called _colorRegex undefined.

After searching on google I found below javascript code. Put this code after your ColorPickerExtender control

<asp:ColorPickerExtender ID="buttonCPE" runat="server" TargetControlID="txtColorCode" PopupButtonID="Image1" SampleControlID="Sample1" SelectedColor="" />

<script type="text/javascript">
//This code must be placed below the ScriptManager, otherwise the "Sys" cannot be used because it is undefined.
Sys.Application.add_init(function() {
// Store the color validation Regex in a "static" object off of
// AjaxControlToolkit.ColorPickerBehavior. If this _colorRegex object hasn't been
// created yet, initialize it for the first time.
if (!Sys.Extended.UI.ColorPickerBehavior._colorRegex) {
Sys.Extended.UI.ColorPickerBehavior._colorRegex = new RegExp('^[A-Fa-f0-9]{6}$');
}
});
</script>

Hope this would be helpful to you.

Hi Friends,

1.) Generate a public and private key from recaptcha.net.
2.) Download recaptcha.dll from the net.
3.) Add this dll as reference in your project.
4.) <%@ Register TagPrefix="recaptcha" Namespace="Recaptcha" Assembly="Recaptcha" %> add this line in your aspx page.
2.) <recaptcha:RecaptchaControl ID="recaptcha1" runat="server" PublicKey="your public key" PrivateKey="your private key" Theme="clean" /> add this control inside the <form> tag.
