>  i want that it should open in the same page without refresh

Do you want an inscreen "pop-up"  ?  If so, you want to add cfwindow

<cfwindow name="popUp" draggable="true" modal="true" resizable="true" initshow="false" height="500" width="760" center="true" bodyStyle="overflow:hidden"/>

Then your javascript could look like this...
 ColdFusion.navigate('thePage.cfm,'popUp');
 ColdFusion.Window.show('popUp');


If you want to replace a portion of your screen, then you need to identify that portion of your screen using either cfdiv or cflayout.

Then when you use Coldfusion.Navigate you will reference that portion of the screen instead.

Your Coldfusion.navigate is missing the container parameter, so it's treated as a normal link.

http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=JavaScriptFcns_24.html

See my example..

Note the container 'theArea'  matches the name of the cflayoutarea name...

ColdFusion.navigate('thePage.cfm,'theArea');

<cflayoutarea position="top" name="theArea">

Your page is throwing a javascript error when it's loaded (be sure you have javascript error notification turned on in your browser so you will be aware of errors)

Since you have an error when the page loads the javascript may not work.  You need to fix the error first.   Try commenting out part of your code to see when the error goes away, that will help you narrow down to the code with the error.

Btw, I thought with cflayout type border that the Center area was required?  
You should check the documentation on that ...

  <td width="34%">#title#</a></td>
  <td width="33%">#DateFormat(postedon,'dddd, mmmm dd, yyyy')#</td>
  <td width="33%">#category#</td>
  <td><input type="button" name="view#newsID#" value="Read" onclick="ColdFusion.navigate('divsource.cfm?view=#newsID#', 'theDiv')">

myself, why are you using   cflayout  with type border?   I assumed it was because you are setting up several areas (including the requried CENTER area).   If you intend to have only one block, then switch to cfdiv as azadi has suggested, his post right before this one what I was saying with cfdiv instead of cflayout.
