# Til/fra-kontakt

Tilføj toggle-switche til PowerShell Universal-apps for at slå indstillinger til eller fra, med hændelseshandlere for ændring og hentning af værdier via Get-UDElement.

Switche slår tilstanden for en enkelt indstilling til eller fra.

Switche er den foretrukne måde at justere indstillinger på mobil. Den valgmulighed, som switchen styrer, samt den tilstand, den er i, bør fremgå tydeligt af den tilhørende inline-etiket.

## Switch

Opret en grundlæggende til/fra-kontakt.

```powershell
New-UDSwitch -Checked $true 
New-UDSwitch -Checked $true -Disabled
```

## OnChange-hændelse

Reager, når en switch-værdi ændres. Variablen `$EventData` vil indeholde, om switchen var markeret eller afmarkeret.

```powershell
New-UDSwitch -OnChange { Show-UDToast -Message $EventData }
```

## Get-UDElement-support

De kan hente værdien af switchen i en anden komponent ved at bruge `Get-UDElement`. Brug egenskaben Checked til at afgøre, om switchen er markeret eller ej.

```powershell
New-UDSwitch -Id 'switch' 
New-UDButton -Text 'Click' -OnClick {
    Show-UDToast -Message (Get-UDElement -Id 'switch').checked
}
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.devolutions.net/powershell-universal/da/apps/components/inputs/switch.md?ask=<question>&goal=<user_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.
