### Description

Gets or sets the page number that the [DocumentServer.Web.DocumentViewer](https://docs.textcontrol.com/tx-text-control-dotnet-server/reference/txtextcontrol-documentserver-web/documentviewer/llms-full.txt) is displaying or should display respectively. Returns 0, if no document is loaded.

### Syntax

```csharp
public int PageNumber { get; set; }
```

```vbnet
Public Property PageNumber As Integer
```

### Examples

`DocumentServer.Web.DocumentViewer.PageNumber` 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
```

### Limitations

Valid values for setting the page number are between 1 and the total number of pages, which is dependent on the loaded document, of course.
