HostingReviewASP.NET | Reliable DotNetNuke Hosting Tutorial. DotNetNuke has come a long way recently with making things much more w3 compliant. This has allowed for more than just cleaner code; it has also allowed for much more control of your website through jQuery and CSS. Also, according to the forums, it looks like things are getting even better for compliance and control. In this tutorial, we will tell you how to create an announcement with a slider in DotNetNuke.

One of our favorite updates of DNN modules to this new compliance, is the DNN Announcements module. With the latest release, we now have the ability to set up the announcements as a list and apply some cool jQuery to it. We decided that we wanted to have the main image fade in and out and the title and description to slide in from the bottom. We came across the s3Slider jQuery plugin which seemed to provide exactly what I was looking for. We have outlined the steps below on how to add it to your DotNetNuke site.

The HTML

1. Add the Announcements module to your page.

2. Click the “Settings” link.

3. Expand the “Announcements Settings”

4. Remove exisiting code from Header Template, Item Template, and Footer Template.

5. In the “Header Template:” text area, enter the following code:

<div id="s3slider">
<ul id="s3sliderContent">

6. In the “Item Template:” text area, enter the following code:
If you want your description area to be at the top of the image area, use the class top in the span.
If you want your description area to be at the bottom of the image area, use the class bottom in the span as I have here.

<li class="s3sliderImage">
[IMAGESOURCE]<span class="bottom"><strong>[TITLE][EDIT]</strong><br />
[DESCRIPTION]<br />
[READMORE]</span>
</li>

7. In the “Footer Template:” text area, enter the following code:

<li class="clear s3sliderImage"></li>

8. Also, in the “Footer Template” area close out the ul and div that was started in the “Header Template” area.

The CSS

In your skin.css file, insert the following styles: (note the widths and heights in the CSS. They need to be exactly the same as the image for the announcemnts.)

#s3slider { width: 500px; height: 242px; position: relative; overflow: hidden;}
#s3sliderContent { width: 500px; position: absolute; top: 0; margin-left: 0;}
.s3sliderImage { float: left; position: relative; display: none;}
.s3sliderImage span { position: absolute; font: 14px/21px Arial, Helvetica, sans-serif; padding: 10px 13px;  width: 500px; background-color: #000; filter: alpha(opacity=70); -moz-opacity: 0.7; -khtml-opacity: 0.7; opacity: 0.7; color: #fff; display: none;}
.top { top: 0; left: 0;}
.bottom { bottom: 0; left: 0;}

The jQuery

Now that we have all of that in place, we can add the jQuery to make it work.

1. Include a refrence to jQuery in your skin. This is already done if widgets are inabled on your site.

2. Download the files from the s3Slider site. http://www.serie3.info/s3slider (link opens in new window)

3. Upload the s3Slider.js file to your skin folder.

4. In your skin file (for example: skin.ascx), enter the following code: (you can put this at the top or the bottom of your skin)

<script type="text/javascript" src="<%= SkinPath%>s3Slider.js"></script>
<script type="text/javascript">
    $(document).ready(function() { 
       $('#s3slider').s3Slider({ 
          timeOut: 7000 
       });
    });
</script>

5. Now just start adding the content of your announcements! Be sure to make your images the same size as what is set in the CSS.
