The samples in this section have not been verified against the latest version of Umbraco.
The example below demonstrates how to add values programmatically using a Razor view. However, this is used for illustrative purposes only and is not the recommended method for production environments.
@using Umbraco.Cms.Core.IO
@using Umbraco.Cms.Core.Serialization
@using Umbraco.Cms.Core.Strings
@inject MediaFileManager MediaFileManager
@inject IShortStringHelper ShortStringHelper
@inject IContentTypeBaseServiceProvider ContentTypeBaseServiceProvider
@inject IContentService ContentService
@inject IMediaService MediaService
@inject IJsonSerializer Serializer
@inject MediaUrlGeneratorCollection MediaUrlGeneratorCollection
@{
// Create a variable for the GUID of the parent where you want to add a child item
var guid = Guid.Parse("32e60db4-1283-4caa-9645-f2153f9888ef");
// Get the page using the GUID you've defined
var content = ContentService.GetById(guid); // ID of your page
// Create a variable for the file you want to upload, in this case the Our Umbraco logo
var imageUrl = "https://our.umbraco.com/assets/images/logo.svg";
// Create a request to get the file
var request = WebRequest.Create(imageUrl);
var webResponse = request.GetResponse();
var responseStream = webResponse.GetResponseStream();
// Get the file name
var lastIndex = imageUrl.LastIndexOf("/", StringComparison.Ordinal) + 1;
var filename = imageUrl.Substring(lastIndex, imageUrl.Length - lastIndex);
// Create a media file
var media = MediaService.CreateMediaWithIdentity("myImage", -1, "File");
media.SetValue(MediaFileManager, MediaUrlGeneratorCollection, ShortStringHelper, ContentTypeBaseServiceProvider, Constants.Conventions.Media.File, filename, responseStream);
// Save the created media
MediaService.Save(media);
// Get the published version of the media (IPublishedContent)
var publishedMedia = Umbraco.Media(media.Id);
// Set the value of the property with alias 'myFile'
content.SetValue("myFile", publishedMedia.Url());
// Save the child item
ContentService.Save(content);
}
Although the use of a GUID is preferable, you can also use the numeric ID to get the page:
@{
// Get the page using it's id
var content = ContentService.GetById(1234);
}
If Models Builder is enabled you can get the alias of the desired property without using a magic string:
@using Umbraco.Cms.Core.PublishedCache
@inject IPublishedContentTypeCache PublishedContentTypeCache
@{
// Set the value of the property with alias 'myFile'
content.SetValue(Home.GetModelPropertyType(PublishedContentTypeCache, x => x.MyFile).Alias, publishedMedia.Url();
}
Instead, we recommend using the for uploading files to your Umbraco website.
See the example below to see how a value can be added or changed programmatically. To update a value of this property editor you need the and the .
