### Output

### Esempi

#### Esempio 1: vista ad albero

```powershell
New-UDTreeView -Node {
    New-UDTreeNode -Name "Root Node" -Id "root1" -Children {
        New-UDTreeNode -Name "Child Node" -Id "child1" -Children {
            New-UDTreeNode -Name "Grandchild Node" -Id "grandchild1" -Leaf
        }
        New-UDTreeNode -Name "Child Node 2" -Id "child2" -Children {
            New-UDTreeNode -Name "Grandchild Node 2" -Id "grandchild2" -Leaf
        }
    }
} -Id "treeview1"
```

Un componente di base per la vista ad albero.

#### Esempio 2: OnNodeClicked

```powershell
New-UDTreeView -Node {
    New-UDTreeNode -Name "Root Node" -Id "root2" -Children {
        New-UDTreeNode -Name "Child Node" -Id "child3" -Children {
            New-UDTreeNode -Name "Grandchild Node" -Id "grandchild3" -Leaf
        }
        New-UDTreeNode -Name "Child Node 2" -Id "child4" -Children {
            New-UDTreeNode -Name "Grandchild Node 2" -Id "grandchild4"
        }
    }
} -Id "treeview2" -OnNodeClicked {
    Show-UDToast -Message "You clicked $($EventData.Id)"
}
```

Una vista ad albero con un blocco di script OnNodeClicked che mostra un toast quando si fa clic su un nodo.

#### Esempio 3: Expanded

```powershell
New-UDTreeView -Node {
    New-UDTreeNode -Name "Root Node" -Id "root3" -Children {
        New-UDTreeNode -Name "Child Node" -Id "child5" -Children {

        New-UDTreeNode -Name "Child Node 2" -Id "child6" -Children {
            New-UDTreeNode -Name "Grandchild Node 2" -Id "grandchild6"  -Leaf
        }
    }
} -Id "treeview3" -Expanded
```

Una vista ad albero espansa per impostazione predefinita.

#### Esempio 4: OnNodeClicked

```powershell

    New-UDTreeNode -Name "Child Node"
}
```

Una vista ad albero con un blocco di script OnNodeClicked che aggiunge un nodo figlio quando si fa clic su un nodo.

#### Esempio 5: icone

```powershell
New-UDTreeView -Node {
    New-UDTreeNode -Name "Root Node" -Id "root5" -Children {
        New-UDTreeNode -Name "Child Node" -Id "child7" -Children {
            New-UDTreeNode -Name "Grandchild Node" -Id "grandchild7" -Leaf -Icon (New-UDIcon -Icon "File")
        } -Icon (New-UDIcon -Icon "Folder") -ExpandedIcon (New-UDIcon -Icon "FolderOpen")
        New-UDTreeNode -Name "Child Node 2" -Id "child8" -Children {
            New-UDTreeNode -Name "Grandchild Node 2" -Id "grandchild8" -Leaf -Icon (New-UDIcon -Icon "File")
        } -Icon (New-UDIcon -Icon "Folder") -ExpandedIcon (New-UDIcon -Icon "FolderOpen")
    }
} -Id "treeview5" -Expanded
```

Una vista ad albero con icone per i nodi.

#### Esempio 6: PreventCollapse

```powershell
New-UDTreeView -Node {
    New-UDTreeNode -Name "Root Node" -Id "root6" -Children {
        New-UDTreeNode -Name "Child Node" -Id "child9" -Children {
            New-UDTreeNode -Name "Grandchild Node" -Id "grandchild9"  -Leaf
        }
        New-UDTreeNode -Name "Child Node 2" -Id "child10" -Children {
            New-UDTreeNode -Name "Grandchild Node 2" -Id "grandchild10"  -Leaf
        }
    }
} -Id "treeview3" -Expanded -PreventCollapse
```

Una vista ad albero espansa per impostazione predefinita che impedisce la compressione quando si fa clic su un nodo.

# 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/it/comandi-powershell/new-udtreeview.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.
