### Esempi

#### Esempio 1: avviso di base

```powershell
New-UDStack -Content {
   New-UDAlert -Severity 'error'  -Title "Error" -Id 'alert1'
   New-UDAlert -Severity 'warning' -Title "Warning" -Id 'alert2'
   New-UDAlert -Severity 'info'  -Title "Info" -Id 'alert3'
   New-UDAlert -Severity 'success' -Title "Success" -Id 'alert4'
} -Direction 'column'
```

L'avviso offre quattro livelli di gravità che impostano un'icona e un colore distintivi.

#### Esempio 2: Text e Title

```powershell
New-UDStack -Content {
   New-UDAlert -Severity 'error' -Title 'Error' -Text 'This is an error alert' -Id 'alert5'
   New-UDAlert -Severity 'warning'  -Title 'Warning' -Text 'This is an warning alert' -Id 'alert6'
   New-UDAlert -Severity 'info' -Title 'Info' -Text 'This is an error info' -Id 'alert7'
   New-UDAlert -Severity 'success' -Title 'Success' -Text 'This is an success alert' -Id 'alert8'

```

È possibile utilizzare il parametro -Title per visualizzare un titolo formattato sopra il contenuto.

## 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.devolutions.net/powershell-universal/it/comandi-powershell/new-udalert.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.
