Below are the controls I was targeting, where on the Internet I found them, and a short description of what it took to create the corresponding theme. If you are not familiar with how theming the TabContainer works, I recommend reading the

Notes:

1. To use this theme, include a link to the CSS file and set the CssClass of the TabContainer control to ‘ajax__tab_technorati-theme’.
2. Make sure you copy the images to your machine and update the path’s in the stylesheet if you change the path. The images for this theme can be found in the download in the img/technorati directory
3. I tested in both IE7 and FF and did not encounter any issues

Windows Live Gallery Tab Theme

I do not particularly care for the Windows Live Gallery style tab, but I thought it might make for an interesting example because the tab headers all contain images. I thought this might be a difficult scenario to support, but because the TabContainer allows for defining a template to use for the tab headers, it was no problem at all.

Here is the sample markup for the ‘Sidebar gadget’ tab panel. Notice, the HeaderTemplate provides us with the flexibility of defining the image and header text that should be used for the ‘Sidebar gadgets’ tab.

<ajaxtoolkit :TabPanel runat="server">
    <headertemplate>
        <div>
            <img src="img/msngallery/sidebar.png"/>
            <div>Sidebar gadgets</div>
        </div>
    </headertemplate>
    <contenttemplate>
    </contenttemplate>
</ajaxtoolkit>

YUI Tab Theme

I blogged about the YUI theme before, but incase you missed it I figured I would mention it again here.

Notes:

1. To use this theme, include a link to the CSS file and set the CssClass of the TabContainer control to ‘ajax__tab_yuitabview-theme’.
2. Make sure you copy the images to your machine and update the path’s in the stylesheet if you change the path. The images for this theme can be found in the download in the img/yui directory
3. I tested in both IE7, IE6 and FF and did not encounter any issues.

Windows Internet Explorer Tab Theme

The last theme I created is based on the tab control that can be found on the Windows Internet Explorer home page.

Notes:

1. To use this theme, include a link to the CSS file and set the CssClass of the TabContainer control to ‘ajax__tab_ie-theme’.
2. Make sure you copy the images to your machine and update the path’s in the stylesheet if you change the path. The images for this theme can be found in the download in the img/ie directory
3. I tested in both IE7 and FF. There appears to be a small issue with the alignment of the first tab in FF. I am working on resolving this.
Notes:

1. To use this theme, include a link to the CSS file and set the CssClass of the TabContainer control to ‘ajax__tab_msngallery-theme’.
2. Make sure you copy the images to your machine and update the path’s in the stylesheet if you change the path. The images for this theme can be found in the download in the img/msngallery directory
3. I tested in both IE7 and FF and did not encounter any issues
