# UserControl

The `UserControl` gives you the ability to create controls that can be used in multiple places within an application or organization. You can include all the code needed for validation of common data you ask the user to input; some examples of this are email addresses, telephone numbers, and postal codes. Another efficient use of the user control is to simply preload a `ComboBox` or `ListBox` with static items you commonly use in almost every application; some examples of this are countries/regions, cities, states, and office locations.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wisej.com/docs/controls/containers/usercontrol.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
