Bye Bye GuidGen.exe!

While developing in Visual Studio and I needed to create a new guid, I always used the “Create GUID” under the Tools dropdown menu. This menuitem started the “guidgen.exe” application and using this was a fine method, until I attended the last DevDays 2009 (The Hague, Netherlands). There I saw a demonstration of a much easier way to create a new guid in Visual Studio by making use of a simple macro. (Thanks Wouter) Below is the explanation on how to implement this macro. 1. Open the Macro Explorer and Load or Create a Macro Project. 2. Inside the macro IDE, create a method to generate a new guid. Imports System Imports EnvDTE Imports EnvDTE80 Imports EnvDTE90 Imports System.Diagnostics Public Module Module1 Sub GenerateGuid() If (DTE.ActiveDocument IsNot Nothing) Then DTE.ActiveDocument.Selection.Text = Guid.NewGuid().ToString("B") End If End Sub End Module 3. Save and close the macro IDE. 4. For the finishing though, create a keyboard shortcut to activate the GeneratGuid macro. I like to use the combination CTRL+K, CTRL+G 5. Now it is so easy to create a new guid…..just by pressing your favourite keyboard shortcut.

Bye Bye GuidGen!

DevDays 2009 (PreConference DeepDive)

Today I visited the first day of the DevDays 2009 (PreConference DeepDive) in The Hague (Netherlands) and attended a session about SharePoint developing by Wouter van Vugt.

After the introduction and agenda, Wouter started with presenting some develop tools you can you use while developing and talked about the pro's and con's of every one of them.

Next was creating custom list templates and how to build your own entity picker controls using classes that are already provided inside the SharePoint object model.

After the lunchbreak he continued with a demo of how he created a complex fieldtype using a entity picker and a resultdialog. How he stored the selected value, which contained some technical data and how to split it in a displaytext and id before displaying in a list. Wouter demonstrated how he used the RenderPattern of the fieldtype to only display the displaytext and hide to technical stuf.

Last part of the session was about how he created his own SharePoint WCM Publishing site that is W3C Complaint. I found this a great demo and he gave me a lot of new idea's to work on.

Overall I had a very interesting day full of How To's, demo's and lots of code examples.

The SharePoint Developer Introduction for .NET Developers

Today I found that Microsoft release a SharePoint Introduction website for .NET develpers.The site is created with SilverLight and contains lots of information on what developer can use when they start with SharePoint.

• Background info
• Webcasts
• Screencasts
• Demo's
• How to's
• Virtual PC's image
• Hands on Labs
• Links to resources and forums
• ...and add some

How to detect when a SharePoint Publishing Page is detached from it's PageLayout

Recently I found a new thing about SharePoint Publishing pages. From within SharePoint Designer, publishing pages can be detached from there pagelayout!

I guess that for some of you this not a a new thing, but I didn't know.

In a normal publishing senario this is also not a common thing to do, because the page is disconnected from the pagelayout and changes to the pagelayout will no longer affect the page. But in certain situations it can be usefull, like using SharePoint Designer to place webparts on a publishing page. Normaly this can only be done from the browser interface. Of course a page can also be attached to a pagelayout again.

To detach a page in SharePoint designer, open the Pages list and right click on the page.


Now you get a dialog 'Detaching from the page layouts http:/xxxx/_catalogs/masterpage/xxxx.aspx will copy its markup into this page, where it can be customized. Changes to the pagelayout will no long affect this page.'

To reattach a page to it's pagelayout, right click on the page again.


After knowing how to detach a page from it's pagelayout, I wanted to find out how a publishing page would know it was detached and after some investigation I found that this information is stored in the listitem for the page. Each publishing page has a field called 'PublishingPageLayout' and this field normaly contains the url of the pagelayout and the name of the content type.
Value format: 'http://xxxx/catalogs/masterpage/xxxx.aspx, ContentTypeName'

But after detaching the pagelayout this field contains another kind of information. Namely an indication that the page is a disconnected publishing page and a reference to the pagelayout is once was connected to.
Value format: 'http://www.microsoft.com/publishing?DisconnectedPublishingPage=true, http://xxxx/_catalogs/masterpage/xxxx.aspx

To detect all disconnected publishing pages in a site collection I created a the following code:

using (SPSite site = new SPSite("http://demosite"))
{
    SPWeb rootWeb = site.RootWeb;

    // Query to get all publishing pages in the sitecollection that are detached from pagelayout.
    // ServerTemplate=850, is template for the Pages lists.
    SPSiteDataQuery dataQuery = new SPSiteDataQuery();
    dataQuery.Webs = "< Webs Scope="SiteCollection">";
    dataQuery.Lists = "< Lists ServerTemplate="850">";
    dataQuery.ViewFields = "< FieldRef Name="FileRef" Nullable="TRUE">";
    dataQuery.Query = "< Where>" +
                            "< Contains>" +
                                "< FieldRef Name="PublishingPageLayout">" +
                                "< Value Type="Text">?DisconnectedPublishingPage=true< /Value>" +
                            "< /Contains>" +
                        "< /Where>";                              

    // Store result in datatable
    DataTable dt = rootWeb.GetSiteData(dataQuery);
    foreach (DataRow row in dt.Rows)
    {
        if (row.IsNull("FileRef"))
        {
            Console.WriteLine("FileRef should not be null!");
            continue;
        }

        // Strip listitem id from fieldref value
        string fieldRef = row["FileRef"].ToString().Trim();
        if (!string.IsNullOrEmpty(fieldRef))
        {
            int pos = fieldRef.IndexOf(";#");
            if (pos > -1)
            {
                fieldRef = fieldRef.Substring(pos + 2);
            }
        }

        Console.WriteLine(fieldRef);
    }
}          

Also you can use the 'Content and Structure Reports' functionality from MOSS to get an overview of all publishing pages that are disconnected from the pagelayout.

To do this, go to the 'Content and Structure Reports' list inside to root site. Create a new item and fill the field like below.

• Report Title: All Pages Disconnected from PageLayout
• Resource Id: (leave blank)
• Resource Id: (leave blank)
• CAML List Type: <Lists ServerTemplate='850' />
• CAML Query: <Where><Contains><FieldRef Name='PublishingPageLayout' /><Value Type='Text'>?DisconnectedPublishingPage=true</Value></Contains></Where>
• Target Audiences: (leave blank)
• Report Description: All publishing pages that are detached from their pagelayout by using SharePoint Designer.

Afer creating a new report, you can access it through the Site Actions button.

SPSiteColumnUsage, Find all references to a site column

When I try to delete a site column from a SharePoint site I often get the message "Site columns which are included in content types cannot be deleted. Remove all references to this site column prior to deleting it."

Well with only a few content types this isn't so hard to click through all content types and checking if the site column is used, but with a lot of them it's no fun and can be a hell of a job.

To make my life a bit easier I decided to create a piece of code that could delete site columns programmatically. I knew that SharePoint object model has a class that can return the usage of content types, namely SPContentTypeUsage. With this class you can tell if a content type is used in one or more lists somewhere inside the complete site collection and what the urls to those lists are.

My guess was that there should also be something like a site column usage, but I was wrong!

After some investigation on MSDN, several SharePoint blogs and good old Reflector, I created a SPSiteColumnUsage class. This class uses the LINQ and SPContentTypeUsage and can find all references to content types and lists where a site columns is in use.

SPSiteColumnUsage
Methods

• GetUsages, this method takes a SPField instance as input argument and returns an array of SPSiteColumnUsage objects.

Properties

• Id, the Id of the site column.
• Scope, the scope of the site column.
• ContentTypeId, the id of a content type where the site column is in use.
• IsUrlToList, indicates if the information is about a list or a content type.
• Url, the server relative to a list where the site column is in use.

Usage example to get info about the site column: Title

using (SPSite site = new SPSite("http://demosite"))
{
    using (SPWeb web = site.OpenWeb())
    {
        SPField field = web.Fields.GetFieldByInternalName("Title);

        Console.WriteLine("Field: {0}", fieldName);
        Console.WriteLine("==============================");

        var usage = SPSiteColumnUsage.GetUsages(field);
        foreach (var u in usage)
        {
            Console.WriteLine("Id: {0}", u.Id);
            Console.WriteLine("Scope: {0}", u.Scope);
            Console.WriteLine("ContentTypeId: {0}", u.ContentTypeId);
            Console.WriteLine("IsUrlToList: {0}", u.IsUrlToList);
            Console.WriteLine("Url: {0}", u.Url);
            Console.WriteLine();
        }
    }
}

See a working example on http://SPSiteColumnUsage.codeplex.com

The class also makes use of the extension method CoppyToArray I created.
For this method see a previous post: Using LINQ to query SharePoint collections

       {

           SPFieldCollection fieldCollection = field.GetType().GetProperty("Fields", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(field, null) as SPFieldCollection;
           if(fieldCollection != null)
           {
               // Get the web context from the collection
               SPWeb web = fieldCollection.Web;

Microsoft SharePoint Designer 2007 is now free

When I first heared the news that Microsoft was going to give away SharePoint Designer 2007 for free, I thought it was a April Fool's joke. But now on April 2nd, I actual believe. :-)

Understanding Field Controls and Web Parts in SharePoint Server 2007 Publishing Sites

I just read an great article from Andrew Connell about the use of Field Controls and Web Parts in MOSS 2007 Publishing sites.

He describes clearly the advantages and disadvantages of using them and that you should considered in the early phase of the implementation of a new publishing site which approach to use.

Read the article on MSDN
Understanding Field Controls and Web Parts in SharePoint Server 2007 Publishing Sites.

SharePoint PublishingWeb class inside out

For a project I've done in the past, I had to create an application that could report all sorts of SharePoint site information. While developing this application, the biggest challenge was to gather information about publishing sites, without the use off the Micosoft.SharePoint.Publishing assembly. The reason for this was that the application also had to run on a WSS only installation of SharePoint. During refactoring I found out that most information was stored in the propertybag of the web.

I created a SharePoint Publishing helper class that can retrieve values for the following PublishingWeb properties and functions.

• GetAvailablePageLayouts
• GetIncludeInNavigation
• IncludeInCurrentNavigation
• IncludeInGlobalNavigation
• IncludePagesInNavigation
• IncludeSubSitesInNavigation
• InheritAlternateCssUrl
• InheritCurrentNavigation
• InheritCustomMasterUrl
• InheritGlobalNavigation
• IsInheritingAvailablePageLayouts
• IsInheritingAvailableWebTemplates
• IsPublishingWeb
• NavigationAutomaticSortingMethod
• NavigationShowSiblings
• NavigationSortAscending
• OrderingMethod
• PagesListId

Using LINQ to query SharePoint collections

I came across a challenge when I wanted to using LINQ on several SharePoint collection classes and I noticed that it wasn't possible to do this....So why not? LINQ lets you query any collection implementing the IEnumerable interface and after some research I found that most of the SharePoint collections don't implement this interface.

Ok, how to overcome this challenge? Arrays implement IEnumerable....Copy the items from the collection to an array! SharePoint collections implement the ICollection interface which provides the method: void CopyTo(Array array, int index), so this should not be a problem. Well it does!

SharePoint collections derive from a class called SPBaseCollection and this class implements ICollection. But because the explicit implementation of CopyTo, this method is private.

For this I wrote a little helper extension method that makes it possible to copy a SharePoint collections (or any class that implements ICollection) to an array of a particular type and validate for null at the same time.

public static class Helpers
{
 public static T[] CopyToArray(this ICollection collection)
 {
     if (collection == null) { return new T[0]; }

     T[] array = new T[collection.Count];
     collection.CopyTo(array, 0);

     return array;
 }
}

Now it is possible to make Linq queries like this:

using (SPSite site = new SPSite("http://demosite"))
{
 using (SPWeb web = site.OpenWeb())
 {
     // Get all webs ordered by Title
     var items1 = web.Webs.CopyToArray< SPWeb>().OrderBy(p => p.Title);
     foreach (var item in items1)
     {
         Console.WriteLine(item.Title);
     }

     // Get all content types grouped by group and ordered by group and name
     var items2 = web.ContentTypes.CopyToArray< SPContentType>().GroupBy(p => p.Group).OrderBy(g => g.Key);
     foreach (IGrouping<> group in items2)
     {
         Console.WriteLine(group.Key);

         foreach (var item in group.OrderBy(p => p.Name))

Create a Fake HttpContext for SharePoint

While coding for SharePoint I usualy start by putting code in a console application to create the nessasary functionaly and on a later stage move it over to a browser application. I do this because I find it speeding up the development cycle, because SharePoint deployment cause a bit of overhead. But once in a while I need the HttpContext.Current to be set and I there isn't one in a console app.

To overcome this problem I created my own WorkerRequest class and a helper method that returns a HttpContext to fake a current http context. Both the class and method take a SPWeb as contructor parameter to put the correct SharePoint context into the http context.

public class FakeSharePointWorkerRequest : SimpleWorkerRequest
{
    private readonly string _ServerName;

    public FakeSharePointWorkerRequest(SPWeb web) : base(web.ServerRelativeUrl, web.Site.WebApplication.IisSettings[SPUrlZone.Default].Path.FullName, string.Empty, string.Empty, null)
    {
        _ServerName = web.Site.HostName;
    }

    public override string GetServerName()
    {
        return _ServerName;
    }
}

public static HttpContext GetFakeHttpContextForSharePoint(SPWeb web)
{
    FakeSharePointWorkerRequest workerRequest = new FakeSharePointWorkerRequest(web);
    HttpContext httpContext = new HttpContext(workerRequest);
    httpContext.Items["HttpHandlerSPWeb"] = web;
    httpContext.Items["HttpHandlerSPSite"] = web.Site;
 
    return httpContext;
}

Usage example

using(SPSite site = new SPSite("http://demosite"))
{
    using(SPWeb web = site.OpenWeb())
    {
        bool httpContextIsFake = false;
        if (HttpContext.Current == null)
        {
            // Must be set before using the SPLimitedWebPartManager in a console app
            HttpContext.Current = GetFakeHttpContextForSharePoint(web);
            httpContextIsFake = true;
        }
 
        // Do your own thingies!
        // .....
 
        // Don't forget to reset the current http context
        if (httpContextIsFake)
        {
            HttpContext.Current = null;
        }                     
    }
}
