Textarea

Alias: Umbraco.TextArea

Returns: String

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.

MVC View Example

Without Modelsbuilder

@{
    if (Model.HasValue("description")){
        <p>@(Model.Value<string>("description"))</p>
    }
}

With Modelsbuilder

@if (!Model.HasValue(Model.Description))
{
   <p>@Model.Description</p>
}

Add value programmatically

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 ContentService
    var contentService = Services;

    // Create a variable for the GUID of your page
    var guid = new Guid("796a8d5c-b7bb-46d9-bc57-ab834d0d1248");

    // Get the page using the GUID you've just defined
    var 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 change
    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 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!");
}
