Label is a non-editable control and can only be used to display a pre-set value.
Data Type Definition Example
Value type
If you want to set a value other than a String, you can define the data using one of the other available Data Types. These include Decimal, Date/time, Time, Integer, and Big integer.
There is also a Value Type: Long string if you need to set a long string value for your Label.
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 =Guid.Parse("32e60db4-1283-4caa-9645-f2153f9888ef"); // 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 'pageLabel'. content.SetValue("pageLabel","A pre-set string value"); // 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 'pageLabel'content.SetValue(Home.GetModelPropertyType(_publishedSnapshotAccessor, x =>x.MyLabel).Alias,"A Preset string");}
