# Customizing download/export buttons in our PDF viewer

The built-in download button can be activated by adding it to [`MainToolbar.ToolbarItems`](https://www.nutrient.io/api/maui/sdk/PSPDFKit.Sdk.Models.Toolbar.MainToolbar.html#ToolbarItems):

```csharp

PSPDFKitController.MainToolbar.ToolbarItems.Add(new ExportPDFButton());

```

If you need more fine-grained control over the download operation, you can easily add your own download button to Nutrient MAUI SDK with [`IDocument.ExportDocumentAsync`](https://www.nutrient.io/api/maui/api/PSPDFKit.Api.IDocument.html#PSPDFKit_Api_IDocument_ExportDocumentAsync_PSPDFKit_Api_IExportConfiguration_) and the possibility of [customizing the toolbar](https://www.nutrient.io/guides/maui/user-interface/main-toolbar/customize-existing-tools.md):

```csharp

var downloadButton = new CustomMainToolbarButton("download-button")
{
    Icon = "download.svg",
    Tooltip = "Download"
};

downloadButton.Clicked += async (s, e) =>
{
    var exportedDocumentContent = await _document.ExportDocumentAsync(
      _document.CreateExportConfiguration());
    var result = await FileSaver.Default.SaveAsync(
        "download.pdf", new MemoryStream(exportedDocumentContent), CancellationToken.None);
};

PSPDFKitController.MainToolbar.ToolbarItems.Add(downloadButton);

```

## Hiding the download button

You can remove the download button from the toolbar by getting the array of current toolbar items via [`MainToolbar.ToolbarItems`](https://www.nutrient.io/api/maui/sdk/PSPDFKit.Sdk.Models.Toolbar.MainToolbar.html#ToolbarItems) and removing the item from the collection:

```csharp

var downloadButton = PSPDFKitController.MainToolbar.ToolbarItems.FirstOrDefault(item => item is ExportPDFButton);
if (downloadButton == null)
{
    return;
}

PSPDFKitController.MainToolbar.ToolbarItems.Remove(downloadButton);

```
