### Description

Gets or sets the zoom behavior of the [DocumentServer.Web.DocumentViewer](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-web/documentviewer/llms-full.txt).

### Syntax

```csharp
public DocumentViewer.ZoomLevel ZoomTo { get; set; }
```

```vbnet
Public Property ZoomTo As DocumentViewer.ZoomLevel
```

### Members

| Value | Description |
|---|---|
| ControlWidth | The current page is zoomed to a size, which makes the horizontal scroll bar unnecessary. |
| FixedSize | The document is zoomed to the value specified by the [DocumentServer.Web.DocumentViewer.ZoomFactor](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-web/documentviewer/zoomfactor-property/llms-full.txt) property. |
| WholePage | The current page is zoomed to a size that allows to view it as a whole. |

### Examples

`DocumentServer.Web.DocumentViewer.ZoomTo` belongs to the legacy Web Forms viewer. In the current ASP.NET Core viewer, configure the server-rendered component through `DocumentViewerSettings.View`; interactive page state and styling are handled by the viewer client.

```csharp
documentViewerSettings.View = TXTextControl.Web.MVC.DocumentViewer.DocumentViewerSettings.ViewMode.Mobile;
if (documentViewerSettings.View != null)
{
    Console.WriteLine("View is available for Document Viewer Settings.");
}
```

```vbnet
documentViewerSettings.View = TXTextControl.Web.MVC.DocumentViewer.DocumentViewerSettings.ViewMode.Mobile
If documentViewerSettings.View IsNot Nothing Then
    Console.WriteLine("View is available for Document Viewer Settings.")
End If
```

### Remarks

The property's default value is `ControlWidth`.
