<div>
the method you use: showModalDialog, will stop execution of the script right at that line, which makes it easier for you to refresh the page. Try this: 
 
function fnOpen(TargetURL,iHeight,iWidth) { 
&nbsp; &nbsp; var sFeatures = fnSetValues(iHeight,iWidth); 
&nbsp; &nbsp; window.showModalDialog(TargetURL, &quot;&quot;, sFeatures); 
&nbsp; &nbsp; history.go(); 
} 
 
 
In the code section there's a full example I created while testing the scenario on different browsers, it shows the current date and time and after refresh (closing the dialog) you will see the time changed. Note that old FireFox browsers do not support showModalDialog. 
 

<pre><code class="code-10 nolinks" id="code-263417">&lt;html&gt;
 &lt;head&gt;
 &lt;title&gt;Test reload with modal dialog&lt;/title&gt;
 &lt;script language=&quot;JavaScript&quot;&gt;
 function showBoxAndReload()
 {
 window.showModalDialog(&quot;http://www.google.nl&quot;);
 history.go();
 }
 &lt;/script&gt;
 &lt;/head&gt;
 
 &lt;body&gt;
 &lt;p&gt;Click on the date to have a modal dialog box and &lt;br /&gt;
 a refresh, note the changing date after closing the dialog:&lt;/p&gt;
 
 &lt;div onclick=&quot;showBoxAndReload()&quot; style=&quot;cursor:pointer;&quot;&gt;
 &lt;script language=&quot;JavaScript&quot;&gt;
 &lt;!--
 // we put this here so we can see something change
 document.write('&lt;b&gt;' + (new Date).toLocaleString() + '&lt;/b&gt;');
 //--&gt;
 &lt;/script&gt;
 &lt;/div&gt;
 &lt;/body&gt;
&lt;/html&gt;

Okay thanks for that. 
 
The page seems to refresh in a sense as the screen flashes and the progress bar goes up but what i need to do is force my Gridview to re-load data. 
 
I've tried adding 
GridView1.Databind(); and 
GridView1.Select(); 
in the page load event of the c# code behind but still the gridview doesn't reflect the new data unless i physcially click the link to the page from the nav or hit refresh on the browser. 
 
Could I make the open event do a redirect on the parent to the same url?

Try the following if this does not cause a correct refresh (but maybe your server settings for that page are not set to cache-expiration correctly): 
 
window.location.reload( true ); 
 
The &quot;true&quot; means: go get the new content from the server. &quot;false&quot; would mean &quot;refresh, but take cache if not expired&quot;.

Am i adding that to the java?

<div class="content wysiwyg-content">
Im opening a child window which updates some info in a database. 
I then need the gridview on the parent page to refresh once the child is closed to reflect the changes. 
 
Any ideas on how I would force page refresh on child close or rebind the gridview? 

<pre><code class="code-1 nolinks" id="code-263382">function fnOpen(TargetURL,iHeight,iWidth) {
 var sFeatures = fnSetValues(iHeight,iWidth);
 window.showModalDialog(TargetURL, &quot;&quot;, sFeatures);
}

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications
