Embed images, videos, and documents in posts in SharePoint

  • Article

Learn how to add SocialAttachment objects to microblog posts, which render as embedded pictures, videos, and documents in SharePoint social feeds.

In a social feed, the simplest form of post content contains only text, but you can also add embedded pictures, videos, and documents. To do this, you use the Attachment property on the SocialPostCreationData object that defines the post. Posts can contain one attachment, which is represented by a SocialAttachment object.

Note

To add a mention, tag, or link to a post's content, you add a SocialDataItem object to the SocialPostCreationData.ContentItems property. For more information, see How to: Include mentions, tags, and links to sites and documents in posts in SharePoint.

The API described in this article is from the .NET client object model. If you're using another API, such as the JavaScript object model, the object names or corresponding API might be different. See Additional resources for links to documentation for related APIs.

Prerequisites for using the code examples to add attachments to a post

The code examples in this article show how to add image, video, and document attachments to microblog posts. These examples are from a console application that uses the following SharePoint assemblies:

  • Microsoft.SharePoint.Client

  • Microsoft.SharePoint.Client.Runtime

  • Microsoft.SharePoint.Client.UserProfilies

To use the examples in this article, you'll need to upload an image, a video, and a document. To use the video example, the video feature must be enabled on the server and the video file must be stored in an asset library. To use the document example in an on-premises environment, Office Online must be configured in the environment. For more information, see Plan digital asset libraries in SharePoint and Configure SharePoint to use Office Online.

For instructions about how to set up your development environment and create a console application, see How to: Create and delete posts and retrieve the social feed by using the .NET client object model in SharePoint.

Example: Embed an image in a post in SharePoint

The following code example publishes a post that contains an embedded image. It shows how to:

Change the placeholder values for the URL variables before you run the code.


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.Client.Social;

namespace EmbedImageInPost
{
    class Program
    {
        static void Main(string[] args)
        {

            // Replace the following placeholder values with the actual values.
            const string serverUrl = "http://serverName/siteName/";
            const string imageUrl = "http://serverName/Shared%20Documents/imageName.jpg";

            // Define the image attachment that you want to embed in the post.
            SocialAttachment attachment = new SocialAttachment()
            {
                AttachmentKind = SocialAttachmentKind.Image,
                Uri = imageUrl
            };

            // Define properties for the post and add the attachment.
            SocialPostCreationData postCreationData = new SocialPostCreationData();
            postCreationData.ContentText = "Look at this!";
            postCreationData.Attachment = attachment;

            try
            {

                // Get the context and the SocialFeedManager instance.
                ClientContext clientContext = new ClientContext(serverUrl);
                SocialFeedManager feedManager = new SocialFeedManager(clientContext);

                // Publish the post. This is a root post to the user's feed, so specify
                // null for the targetId parameter.
                feedManager.CreatePost(null, postCreationData);
                clientContext.ExecuteQuery();
                Console.Write("The post was published.");
                Console.ReadLine();
            }
            catch (Exception ex)
            {
                Console.Write("Error publishing the post: " + ex.Message);
                Console.ReadLine();
            }
        }
    }
}

Embed a video in a post in SharePoint

The following code example publishes a post that contains an embedded video. It shows how to:

This example requires the video features to be enabled on the server and the video file to be uploaded to an asset library. See the prerequisites for using the code examples for more information.

Change the placeholder values for the URL variables before you run the code.


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.Client.Social;

namespace EmbedVideoInPost

        static void Main(string[] args)
        {
            // Replace the following placeholder values with the actual values.
            const string serverUrl = "http://serverName/siteName/";
            const string videoUrl = "http://serverName/Asset%20Library/fileName?Web=1";

            try
            {

                // Get the context and the SocialFeedManager instance.
                ClientContext clientContext = new ClientContext(serverUrl);
                SocialFeedManager feedManager = new SocialFeedManager(clientContext);

                // Get the video attachment from the server.
                ClientResult<SocialAttachment> attachment = feedManager.GetPreview(videoUrl);
                clientContext.ExecuteQuery();

                // Define properties for the post and add the attachment.
                SocialPostCreationData postCreationData = new SocialPostCreationData();
