Sharepoint 2010 Adding a "Publishing Image" to a Sharepoint List programmatically.

What is "Publishing Image" content type?

"Publishing Image" is a content type which will bind the image with all its properties and will show it on the screen with those properties applied. The properties like height width etc.

What my task was?

My task was to add a "Publishing Image" content type with Display Name as "Rollup Image" in the content type list "Post". This was a site level feature, once i activate this feature all the blog type site with SharePoint List "Post" will have an extra field "Rollup Image". Please have a look at the 2 pictures which can give you a clear idea.

The 1^st from the above one is new post screen. and the 2^nd one comes when you click to add a new image reference.

Solution

1. Open a visual studio 2010
2. Add new project
3. Empty Sharepoint Project > Deploy as Farm Solution > Finish.
4. In the visual studio solution project select "Features > Feature1 > Feature1.feature".
5. Right click "Add event receiver".
6. I used this code to achieve it.
   
   

   /// <summary>
   /// Add a field name "Rollup Image" to a content type "Post".
   /// "Post" is the content type used in the Site Template blog.
   /// </summary>
   /// <param name="properties"></param>
   public override void FeatureActivated(SPFeatureReceiverProperties properties)
   {
       SPSecurity.RunWithElevatedPrivileges(delegate
       {
           using (SPWeb _web = ((SPSite)properties.Feature.Parent).RootWeb)
           {
               //Post is the content type list which is on the blogs.
               SPContentType _contentType = _web.ContentTypes["Post"];
   
               if (_contentType != null)
               {
                   //PublishingRollupImage is the static name for the "Publishing Image "
                   if (!_contentType.Fields.ContainsFieldWithStaticName("PublishingRollupImage"))
                   {
                       //Name of the column to be added to the list content type post
                       SPField _field = _web.AvailableFields["Rollup Image"];
                       SPFieldLink _fieldText = new SPFieldLink(_field);
   
                       if (_contentType.FieldLinks[_fieldText.Id] == null)
                       {
                           _contentType.FieldLinks.Add(_fieldText);
                       }
                       _contentType.Update(true);
                   }
               }
           }
       });
   }

7. Deploy the solution.

How to verify this?

1. Open the Sharepoint Site.
2. Site Actions > Site Settings > Site Content Types
3. Click "Post" in "List Content Type".
4. You can see the newly added column in the image below. For checking the above 2 images you should go to the "Post" sharepoint list in the blog site.
   

Please feel free to ask question, I will be more glad to answer your question.

Sharepoint 2010 Enabling "Target Audience" programmatically for Sharepoint List

In this blog i have tried and explained how enable the "Target Audience" using C# for a list. But first I will show you how to enable manually.

Why do we have to enable "Target Audience" field?

To filter the data using audience in Content Query Web Part we have to enable this feature.

Manually

1. Go to Sharepoint Site
2. Site Actions > View All Site Content
3. Select the SharePoint List you want to enable target audience.
4. List Settings > Audience targeting settings
5. Select the check box and save.
   
6. This will add a field name "Target Audience" in the list.
7. You can now give Item level target audience.

Programmatically

1. In the event receiver where you are creating a Sharepoint List.
2. Just use the code given below.
   

   #region Enable Target Audience
   
   XmlElement _fldElement = new XmlDocument().CreateElement("Field");
   _fldElement.SetAttribute("ID", "{61cbb965-1e04-4273-b658-eedaa662f48d}");
   _fldElement.SetAttribute("Type", "TargetTo");
   _fldElement.SetAttribute("Name", "Target_x0020_Audiences");
   _fldElement.SetAttribute("StaticName", "Target_x0020_Audiences");
   _fldElement.SetAttribute("DisplayName", "Target Audiences");
   _fldElement.SetAttribute("Required", "FALSE");
   _list.Fields.AddFieldAsXml(_fldElement.OuterXml);
   
   _list.Update();
   
   #endregion

3. That should be it. See to the list if that column is there!

Thank you and hoping the blog helped you.

Sharepoint 2010 Master page issue with re-deployment with new changes from Visual Studio solution

PROBLEM :- There is a problem with the current process. For the first time this will work but if you make any changes to the master page and re-deploy the same solution will not deploy this new master page with the changes on the server.


In my last post "SharePoint 2010 Deploy Master Page using Visual Studio Solution Project and Set it as Default Master Page.", i explained how to add a master page and set it as a default. I suggest to read the last blog first.

What causes the issue?

Answer: When a file is deployed to the server using a Visual Studio Solution, the file gets deleted first and than added back to server. But when we assign a file as a Default Master Page it "CANNOT" be deleted. So just follow the below given steps to make it a fix.

Solution

Just write a deactivating event in the feature receiver setting V4.master as a master page. Please checkout the code below.

/// <summary>
/// Set the v4.master as default master for site.
/// </summary>
/// <param name="properties"></param>
public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
{
    SPSecurity.RunWithElevatedPrivileges(delegate
    {
        using (SPWeb _web = ((SPSite)properties.Feature.Parent).RootWeb)
        {
            Uri _siteMaster = new Uri(string.Format("{0}/_catalogs/masterpage/v4.master", _web.Url));
            _web.MasterUrl = _siteMaster.AbsolutePath;
            _web.CustomMasterUrl = _siteMaster.AbsolutePath;
            _web.Update();
        }
    });
}

Hope this was helpful to you. Thanks for reading the blog.

SharePoint 2010 Deploy Master Page using Visual Studio Solution Project and Set it as Default Master Page.

This blog will give an understanding of how to add a master page using a Visual Studio solution project. Also setting the same master as a default for site.

STEP 1 : Adding a Master Page using Module

1. Open a visual studio 2010
2. Add new project
3. Empty Sharepoint Project > Deploy as Farm Solution > Finish.
4. Add New Item > Select "Module" > I named it as "MasterPage".
5. Delete the "Sample.txt" which gets added in the module by default.
6. Add new MainMasterPage.master. Do whatever change you want to it.
7. Open the elements.xml file of "MasterPage" module. You will have to make some modification shown below.
   
   
   

   <?xml version="1.0" encoding="utf-8"?>
   <Elements xmlns="http://schemas.microsoft.com/sharepoint/">
       <Module Name="MasterPage" List="116" Url="_catalogs/masterpage">
           <File Path="MasterPage\MainMasterPage.master" Url="MainMasterPage.master" Type="GhostableInLibrary">
               <Property Type="string" Name="Title" Value="My Main Master Page"/>
           </File>
     </Module>
   </Elements>

8. Please verify the below given text i made change in the original one. This is MOST IMPORTANT!!!.

   List="116" Url="_catalogs/masterpage"

   Url="MainMasterPage.master" Type="GhostableInLibrary"

9. Once this is set just deploy the project.

STEP 1.1 : Verify the file got uploaded

1. Open the site in SharePoint Designer 2010.
2. All Files > _catalogs > MasterPage
3. The file should be at this location because if you see the element.xml above in the url we have given the path of "_catalogs/masterpage". That's it we now achieved the first step of adding a master file to the site.

STEP 2 : Apply the page as a default master page

1. In the visual studio solution project select "Features > Feature1 > Feature1.feature".
2. Right click "Add event receiver".
3. Put this code.
   
   

   /// <summary>
   /// Set the MainMasterPage.master as default master for site.
   /// </summary>
   /// <param name="properties"></param>
   public override void FeatureActivated(SPFeatureReceiverProperties properties)
   {
       SPSecurity.RunWithElevatedPrivileges(delegate
       {
           using (SPWeb _web = ((SPSite)properties.Feature.Parent).RootWeb)
           {
               Uri _siteMaster = new Uri(string.Format("{0}/_catalogs/masterpage/MainMasterPage.master", _web.Url));
               _web.MasterUrl = _siteMaster.AbsolutePath;
               _web.CustomMasterUrl = _siteMaster.AbsolutePath;
               _web.Update();                   
           }
       });
   }

4. Right click the project and deploy the solution.

I hope this helps you with the deployment of master page and setting it as a default.

PROBLEM :- There is a problem with the current process. For the first time this will work but if you make any changes to the master page and re-deploy the same solution will not deploy this new master page with the changes on the server. Please read my next blog "Sharepoint 2010 Master page issue with re-deployment with new changes from Visual Studio solution" for the solution.
