If you ever wondered how you can do this “without code” J you can do it by placing two WebParts on a SP page; an InfoPath Form WebPart and a Query String Filter WebPart. You then make a connection between the two passing the value from the Query String Filter to the InfoPath form WebPart.

Note the following:

• This will not work for “lookup” fields if you use the default SP list InfoPath form (That’s Why I thought you can’t do it originally for lookups). However, you can expose the “lookup” dropdown field if you create a new InfoPath form using the method below.
• Make sure you add the “field” in your InfoPath to the list of allowable fields to be used in connections.

Retrieve Activities from the SharePoint 2010 Activity Feeds

I've recently worked on a webpart that will let you retrieve activities for the logged in user and display them using the default template of the activity.

The webpart gets an instance of the ActivityManager object and the UserProfile object of the logged in user. After you get the reference, you can then retrieve the activity events using the ActivityManager.GetActivitiesByUser() method. Then you retrieve the resource (.resx) file corresponding to that particular ActivityEvent replacing the values with the ActivityEvent values as shown the code below


            string userName = Environment.UserDomainName + "//" + Environment.UserName;
            SPServiceContext currentContext = SPServiceContext.GetContext(SPContext.Current.Site);

            //Get the UserProfileManager from SPServiceContext.
            UserProfileManager userProfMan = new UserProfileManager(currentContext);

            //Get the current user.
            UserProfile currentUser = userProfMan.GetUserProfile(userName);

            //Get the ActivityManager from the user and context.
            ActivityManager activityMan = new ActivityManager(currentUser, currentContext);

            ActivityEventsCollection eventsCollection = activityMan.GetActivitiesForMe(10);

            foreach (ActivityEvent activity in eventsCollection)
            {
                ActivityType activityType = activityMan.ActivityTypes[activity.ActivityTypeId];
                ActivityTemplate activityTemplate = activityType.ActivityTemplates[bool.FalseString];
                string templateStr = SPUtility.GetLocalizedString(activityTemplate.TitleFormatLocStringResourceFile, "$Resource:" + activityTemplate.TitleFormatLocStringName, (uint)CultureInfo.CurrentUICulture.LCID);
              
                //The line below returns null for the "Publisher".
                //HOWEVER, If i step through the code in debug mode, the values get populated eventually
                templateStr = templateStr.Replace("{Publisher}", activity.Publisher.Name);

                //Then you will need to output the templateStr to the UI.
                //EncodedLiteral.Text += templateStr
            }


What you might notice is that you will get an "Null" Exception when you query the Publisher and the Owner properties of the ActivityEvent object. Stepping through the code, you will notice that the values will eventually load, and you will not get the exception. I'm not sure why this happens. If anyone knows, Feel free to leave a comment. A solution for this would be to get the TemplateVariable property and parse it as an XmlDocument object and then use that to get the Event values.

Add a WebPart into the Rich Content of a wiki page in SP2010

After a long struggle looking in the SP API for how to insert a WebPart in the "rich content" of a wiki page, i found the answer. Thanks to Stefan Stanev for posting the answer to my question.

I have modified the code a bit to suite my needs

SPSite osite = properties.Feature.Parent as SPSite; 

   using (SPWeb oWeb = osite.OpenWeb(osite.RootWeb.ID)) 

  {

    //SPLimitedWebPartManager webpartsManager =  oWeb.GetLimitedWebPartManager(oWeb.RootFolder.WelcomePage, PersonalizationScope.Shared);

   SPFile file = oWeb.GetFile(oWeb.RootFolder.WelcomePage);

   Guid cwpID = AddWebPartToRichContent(file);

   Guid xlvID = AddListWebPartToRichContent(file, "Announcements");

  }

private Guid AddWebPartToRichContent(SPFile file)

{

// NOTE: we assume that the SPFile was checked out

// get the limited wp manager for that SPFile

SPLimitedWebPartManager mngr = file.GetLimitedWebPartManager(PersonalizationScope.Shared);

// create a sample content editor wp

ContentEditorWebPart cwp = new ContentEditorWebPart();

cwp.Title = "My editor";

// add the web part to the special wpz zone

mngr.AddWebPart(cwp, "wpz", 0);

// store the web part's internal ID

Guid cwpID = mngr.GetStorageKey(cwp);

// get the list item for that SPFile

SPListItem item = file.Item;

// update the PublishingPageContent field value

item["WikiField"] += this.GetEmbeddedWPString(cwpID);

// update the item

item.SystemUpdate(false);

// the SPFile instance can be checked in, published, approved afterwards

return cwpID;

}

private Guid AddListWebPartToRichContent(SPFile file, string listTitle)

{

// NOTE: we assume that the SPFile was checked out

// get the limited wp manager for that SPFile

SPLimitedWebPartManager mngr = file.GetLimitedWebPartManager(PersonalizationScope.Shared);

// create a sample XLV

XsltListViewWebPart xlv = new XsltListViewWebPart();

// get a target list

SPList list = file.ParentFolder.ParentWeb.Lists[listTitle];

// set the ListName property with the capitalized list ID w/o the curly braces

xlv.ListName = list.ID.ToString("B").ToUpper();

// use the schema of the default view

xlv.ViewGuid = list.DefaultView.ID.ToString("B").ToUpper();

// add the web part to the special wpz zone

mngr.AddWebPart(xlv, "wpz", 0);

// store the web part's internal ID

Guid xlvID = mngr.GetStorageKey(xlv);

// get the list item for that SPFile

SPListItem item = file.Item;

// update the PublishingPageContent field value

item["WikiField"] += this.GetEmbeddedWPString(xlvID);

// update the item

item.SystemUpdate(false);

// the SPFile instance can be checked in, published, approved afterwards

return xlvID;

}

private string GetEmbeddedWPString(Guid wpID)

{

const string form = @"

                                    

                                    

                                    

                                    

                                   

";

// set the web part's ID as part of the ID-s of tho div elements

return string.Format(form, wpID);

}

I hope this would help someone out there.

Twitter webpart for SharePoint 2010

I've been working on a couple of social solutions for SharePoint 2010. One of the solutions was a Twitter webpart that will search for tweets based on a keyword, or a user.
The following properties can be customized:

• Display poster profile image
• Tweets limit
• Search by a user and/or words
• Refresh intervals (60 sec default)

The webpart will refresh on a set interval to load more tweets automatically.
It is also possible to tag the tweets with keywords from SharePoint taxonomy.

SharePoint 2010 reaches RTM!

Today SharePoint 2010 RTM was released. This is an exciting milestone for Microsoft. Volume License customers will be able to download SharePoint on the 27th of April if they have an active SA. Customers who do not have the SA will be able to download it on 1st of May.

Activity Feed being empty with Claims Enabled Web Applications

I was having trouble aggregating my colleagues' activities into my news feed page. After searching for a solution on the internet, found out that i needed to do two things

• Add colleagues 
• Enable the "User - Activity Feed Job" because it was disabled for some reason.

Then when i went to the "My newsfeed" page, i found no feeds still. I didn't get the feeds in my "recent activities" either. After some investigations i found out that the "All Authenticated" users for the Claims provider that the Web Application is using must be added to have read permissions on the social data. You can do this by going to the User Profile Management page and then going to the "Manage User Permissions" page.

After doing this, and then re-running the job. The feeds appeared :)

New SharePoint and Office 2010 Image availabe

Overview

This download contains a two Virtual Machine set for evaluating and demonstrating Office 2010 and SharePoint 2010. 

Virtual machine “a” contains the following pre-configured software: 

1. Windows Server 2008 SP2 Standard Edition x64, running as an Active Directory Domain Controller for the “CONTOSO.COM” domain with DNS and WINS 

2. Microsoft SQL Server 2008 SP2 Enterprise Edition with Analysis, Notification, and Reporting Services 

3. Microsoft Office Communication Server 2007 R2 

4. Visual Studio 2010 Beta 2 Ultimate Edition 

5. Microsoft SharePoint Server 2010 Enterprise Edition Beta 2 

6. Microsoft Office Web Applications Beta 2 

7. FAST Search for SharePoint 2010 Beta 2 

8. Microsoft Project Server 2010 Beta 2 

9. Microsoft Office 2010 Beta 2 

10. Microsoft Office Communicator 2007 R2 

Virtual machine “b” contains the following pre-configured software: 

1. Windows Server 2008 R2 Standard Evaluation Edition x64, joined to the “CONTOSO.COM” domain 2. Microsoft Exchange Server 2010 Active directory has been preconfigured over 200 “demo” users with metadata in an organizational structure. All of these user profiles have been imported and indexed for search within SharePoint Server 2010, with “contoso\administrator” granted administrator permissions. 

SharePoint Server 2010 has been configured in a “Complete” farm using Kerberos authentication and the default SQL Server 2008 instance for data, and has a site collection created using the Team Site template at http://intranet.contoso.com/ and a FAST Search Center at http://intranet.contoso.com/search/. 

Performance Considerations 

1. If possible, unpack and run the VM image on a separate, fast hard drive (7200 RPM or better) from the operating system of the host machine. If this is being done on a laptop, a second internal drive or external eSATA drive works best, though USB 2.0 (make sure it's 2.0, 1.1 is too slow) or Firewire is acceptable. For absolute best performance use a second internal SSD drive.
