Two possibilities spring immediately to mind:
The "next" button's CausesValidation property is set to false.
The "next" button is in a different ValidationGroup to the other controls.

Make sure the CausesValidation property is set to true on the buttons that you want validation to occur when clicked.
<asp:Button CausesValidation="TRUE" runat="server" />

$("input[id*='txtMultiBrand']").each(function (index) {
if ($.inArray($(this).val(), valueArray) == -1) {

is the calendar extender an ajax extender or did you mean the asp calendar control? Either way I've tried both in your same situation described and it works. Try posting some code you are using so we can see where the issue lies and be of further assistance.
Edit: here's the code I used from yours. I took out the usercontrols so I could debug the page and it seemed to work. Here's an a screenshot

CSS solution that worked for me:
.ajax__calendar_container
{
position :absolute;
z-index : 100003 !important;
}
Make sure to use !important declaration. Without it z-index was always overwrited by higher settings. You should also check z-index in css for popup dialog and it's background.

Need urgently.
Thanks.

Please try
DropDownList ddlpages = (DropDownList)lvParentMenus.Items[0].FindControl("ddlPagesList");

Have you tried to use runat=server property in TABLE in Listview?

Check whether the call to the ValidateDropDown method is in the generated HTML. Use Firebug to debug the JavaScript.

Please help #!

You say your problem is that the buttons are not into view. You can scroll your control into view by using this technique. Or you can load the page on my screen, I have a bigger monitor.
What I'm trying to say: if it's visible on your screen after redesign, anybody with a smaller screen or a resized browser window still won't see it.
If you want to-the-point help on your HTML design, I suggest you upload a trimmed down example of your problem that we can copy and paste to test (or show an online link of your current page).

Lose the tables, or at the very least, remove the unnecessary <div> and <br> tags.

Another option, provided you do not have to support old versions of Internet Explorer, is to use position: fixed to "stick" your buttons to the bottom of the viewable window.
<div style="position: fixed; bottom: 0px;">
<asp:Button ID="btn_view1_back" ... />
<asp:Button ID="btn_view1_next" ... />
</div>
