Textarea is an HTML textarea control for multiple lines of text. It can be configured to have a fixed character limit, as well as define how big the space for writing can be. By default, there is no character limit unless it's specifically set to a specific value like 200 for instance. If you don't specify the number of rows, 10 will be the amount of rows the textarea will be occupying, unless changed to a custom value.
See the example below to learn how a value can be added or changed programmatically to a Textarea property. 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.
@using Umbraco.Cms.Core.Services;@inject IContentService Services;@{ // Get access to ContentServicevar contentService = Services; // Create a variable for the GUID of your pagevar guid =newGuid("796a8d5c-b7bb-46d9-bc57-ab834d0d1248"); // Get the page using the GUID you've just definedvar content =contentService.GetById(guid); // Set the value of the property with alias 'description'content.SetValue("description","This is some text for the text area!"); // 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:
@using Umbraco.Cms.Core.PublishedCache;@inject IPublishedSnapshotAccessor _publishedSnapshotAccessor;@{ // Set the value of the property with alias 'description' content.SetValue(Home.GetModelPropertyType(_publishedSnapshotAccessor, x => x.Description).Alias, "This is some text for the text area!");
}
