Theming SharePoint (6 of Infinite)

The SharePoint Happenings Blog has a great post about customizing forms for your lists. I am using this to get rid of certain fields that I do not want to be entered when a new item is added. For instance, I default the Status field to “In Development” (Open/Assigned) and force the user to pick this by hiding the field.

Theming SharePoint (4 of Infinite)

Michael O’Donovan brings us a blog post about custom (left) navigation in SharePoint. That is what I will be tackling today so I can move away from the ugly Tables and use a more common UL/LI scheme.

Here is my class:

But how do we install it? Good question John. Why thank you John! Copy it to your server. Open the GAC (C:\WINDOWS\assembly) and drag and drop. Now perform an IISRESET and add the control to your master page in the usual way:

        <asp:ListNavigation id="CustomListNavigation" DataSourceId="QuickLaunchSiteMap" runat="server" />
    </div>
</SharePoint:SPNavigationManager>

It is important to note that the UL/LI scheme is incredibly flexible. You can make them horizontal, drop down menus or keep them as standard vertical lists. Once the control is in place, the designer (CSS for the win here) can take over. For this reason, this type of navigation scheme can also make its way to the top navigation bar. But I will leave that up to you as I have got to get back to work!

Update (9:58): Here are the CSS styles I use with setting AppendLevel to true in the control tag of the master page. There is some pretty wacky CSS going on here and I am sure it can be cleaned up, but it works in IE7 and is a good place to start.

Theming SharePoint (3 of Infinite)

A short one here. When you are going to start theming SharePoint and need to figure out exactly what styles need to be changed, the best tool you can ever get is one like the Web Developer extension for FireFox. Now I hate FireFox, especially 3.x, but I run 2.x at work for the sole purpose of the WebDev extension. Right click on the page, select “Select CSS” under the CSS menu and click away. It will automatically pull CSS styles from the included sheets that pertain to the selected element. This will save hours of time digging through core.css and the page’s source HTML. Trust me.

You may be asking “What else will he post about?” Well, I plan to go through the actual creation of a master page file for the theme from Focused Games but first I have to figure out a few things like how to redo how SharePoint outputs stuff (tables – blegh!). Yeah, I am going that far because I am sick of seeing SharePoint sites that look like SharePoint. In between here and there I will keep touching on the general tidbits of information that may help.

Theming SharePoint (2 of Infinite)

Here is a good blog post about theming the SharePoint top navigation. Today’s post is all about CSS, so pull out your favorite design books… and then light them on fire because they will be of no use here. You’ll want to start off by pulling and probably printing the core.css file that is provided with SharePoint. It may also be a good idea to print the source code of your new non-designed master page. Why? This will give you an idea of what HTML code SharePoint produces and what CSS classes it uses.

Once that is done, go ahead and create a new CSS file in the “Style Library” of your site. Go into site settings for the main site and override the style sheet with that file. This can be found at the bottom. Now you are good to go! Almost… more to come soon.

Here is a little of the CSS you may be employing. This applies to the “Upload Document” style pages and gets rid of the background images and borders:

Theming SharePoint (1 of Infinite)

I am beginning to do themes (master pages) for some SharePoint sites, so here is part 1 of an infinite number of parts (because of how difficult theming SP is) of “Theming SharePoint.”

Assumptions:

  • Theming will be done in several ways.
  • Any advanced theming will include modifying core template pages.
  • The amount of modification is directly related to the number of work arounds needed.
  • This is going to suck.

Initial Steps

  1. Copy default.master from main site catalog directory. Rename and open.
  2. Erase everything.
  3. Open default.master in new window.
  4. Add each individual part, one by one to the page without any layouts.
    1. I started with the header, copy pretty much everything over.
    2. Remove all table tags and __designer: attributes.
    3. Remove all div, p, b, and style tags.

After doing this, you should have a horrible looking page with all the content on it. The important piece here is to get the content working so it is possible to figure out what place holders do what. Next post will be about layouts, the CSS hacks and more.

Update (18:25): Added more detail to the last step. Basically strip everything but the place holders and the controls inside of them.

Installing SharePoint 2007 on Windows Server 2008

Ben Curry has made an excellent post about installing SharePoint 2007 on WS2008 by slipstreaming SP1 updates. I am now running SharePoint and AD on my internal server!

Hosting A Page Inside A SharePoint Page

One of the tasks I had recently was to get not only a web page into a SharePoint page but also pass in parameters from the Query String. Let’s say I am going to create the page at http://localhost/sharepoint/mypage.aspx in a normal way. In order to host a page inside that SharePoint page, we can use a Page Viewer Web Part, but this limits what can be done. Instead, we can create a custom web part to do the work…

Please excuse me if the code isn’t exactly correct. I do not have the code in front of me right now and will update it when I do.

public class CustomWebPart : WebPart {
    public override void Render(HtmlTextWriter writer){
        string rawUrl = Context.Request.Url.OriginalString;
        int index = rawUrl.IndexOf("?");
 
        string query = String.Empty;
        if(index != -1) query = rawUrl.Substring(index);
 
        writer.Write(
            "<iframe src='http://localhost/sharepoint/myOtherPage.aspx" + query + "' width='100%' height='765px'/>"
        );
    }
}
