The user picker opens a panel to pick a specific user from the Users section. The value saved is of type IPublishedContent.
Data Type Definition Example

MVC View Example
Getting the Value of the property will return the user ID - properties of the User can be accessed by referencing UserService.
Without Modelsbuilder
@using Umbraco.Cms.Core.Services;@inject IUserService UserService;@{if (Model.Value("userPicker") !=null) {var us = UserService;var username =us.GetUserById(Model.Value<int>("userPicker")).Name;<p>This isthe chosen person: @username</p><p>This returns the id value of chosen person:@Model.Value("userPicker")</p> }}
With Modelsbuilder
@using Umbraco.Cms.Core.Services;@inject IUserService UserService;@{if (Model.UserPicker!=null) {var us = UserService;var user =us.GetUserById((int)Model.UserPicker);<p>This isthe chosen person:@user.Name</p><p>This returns the id value of chosen person:@user.Id)</p> }}
Add values programmatically
See the example below to see how a value can be added or changed programmatically. To update a value of a property editor you need the Content Service.
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.
@inject IContentService Services;@{ // Get access to ContentServicevar contentService = Services; // Create a variable for the GUID of the page you want to updatevar guid =newGuid("796a8d5c-b7bb-46d9-bc57-ab834d0d1248"); // Get the page using the GUID you've definedvar content =contentService.GetById(guid); // ID of your page // Set the value of the property with alias 'userPicker'. The value is the specific ID of the usercontent.SetValue("userPicker",-1); // Save the changecontentService.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 idvar content =contentService.GetById(1234); }
If Modelsbuilder is enabled you can get the alias of the desired property without using a magic string:
@inject IPublishedSnapshotAccessor _publishedSnapshotAccessor;@{ // Set the value of the property with alias 'userPicker'content.SetValue(Home.GetModelPropertyType(_publishedSnapshotAccessor, x =>x.UserPicker).Alias,"Umbraco Demo");}
