# Textbox
How to use the TextBox property editors in Umbraco CMS.
`Alias: Umbraco.Textbox`
`Returns: String`
Textbox is an HTML input control for text. It can be configured to have a fixed character limit. The default maximum amount of characters is 512 unless it's specifically changed to a lower amount.
## Data Type Definition Example
## Content Example
### Without a character limit
### With a character limit
## MVC View Example
### Without Modelsbuilder
```csharp
@{
// Perform an null-check on the field with alias 'pageTitle'
if (Model.HasValue("pageTitle")){
// Print the value of the field with alias 'pageTitle'
@(Model.Value("pageTitle"))
}
}
```
### With Modelsbuilder
```csharp
@{
// Perform an null-check on the field with alias 'pageTitle'
@if (!Model.HasValue(Model.PageTitle))
{
// Print the value of the field with alias 'pageTitle'
@Model.PageTitle
}
}
```
## 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](/umbraco-cms/13.latest/reference/management/services/contentservice.md).
{% hint style="info" %}
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.
{% endhint %}
```csharp
@using Umbraco.Cms.Core.Services;
@inject IContentService Services;
@{
// Get access to ContentService
var contentService = Services;
// Create a variable for the GUID of the page you want to update
var guid = new Guid("32e60db4-1283-4caa-9645-f2153f9888ef");
// Get the page using the GUID you've defined
var content = contentService.GetById(guid); // ID of your page
// Set the value of the property with alias 'pageTitle'
content.SetValue("pageTitle", "Umbraco Demo");
// 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:
```csharp
@{
// 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:
```csharp
@using Umbraco.Cms.Core.PublishedCache;
@inject IPublishedSnapshotAccessor _publishedSnapshotAccessor;
@{
// Set the value of the property with alias 'pageTitle'
content.SetValue(Home.GetModelPropertyType(_publishedSnapshotAccessor, x => x.PageTitle).Alias, "Umbraco Demo");
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.umbraco.com/umbraco-cms/13.latest/fundamentals/backoffice/property-editors/built-in-umbraco-property-editors/textbox.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
