# Conditions

Vous pouvez utiliser le composant `<Condition />` dans les widgets pour afficher optionnellement des sections du widget.

## Bloc de script

Utilisez l'attribut `ScriptBlock` pour définir un bloc de script qui détermine la valeur de la condition. Le bloc de script doit retourner true ou false.

```xml
<Condition ScriptBlock="$Errors -eq $null">
</Condition>
```

## Contenu enfant

La section `ChildContent` s'affiche si la condition est vraie.

```markup
<Condition ScriptBlock="$Errors -eq $null">
   <ChildContent>
      <Alert Message="Success!" />
   </ChildContent>
</Condition>
```

## Else

La section `Else` s'affiche si la condition est fausse.

```markup
<Condition ScriptBlock="$Errors -eq $null">
   <ChildContent>
      <Alert Message="Success!" />
   </ChildContent>
   <Else>
      <Alert Message="Failure!" Type="error" ShowIcon="true" />
   </Else>
</Condition>
```
