### Canceling save in Save events

The [BeginSave](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfViewerControl.html#Syncfusion_Windows_PdfViewer_PdfViewerControl_BeginSave) event occurs before initiating the save operation of the PDF file. It also allows you to cancel the save operation using the [Cancel](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.BeginSaveEventArgs.html#Syncfusion_Windows_PdfViewer_BeginSaveEventArgs_Cancel) property of [BeginSaveEventArgs](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.BeginSaveEventArgs.html). The following code shows how to wire the event in the [PdfViewerControl](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfViewerControl.html).

{% tabs %}
{% highlight c# %}

public MainWindow()
{
InitializeComponent();
// Wire the `BeginSave` event.
PdfViewer.BeginSave += PdfViewer_BeginSave;
// Load the PDF file
PdfViewer.Load("../../Data/Windows Store Apps Succinctly.pdf");
}

#region Events
private void PdfViewer_BeginSave(object sender, BeginSaveEventArgs e)
{
// Insert your code here

// Cancel the save operation
e.Cancel = true;
}
#endregion

{% endhighlight %}
{% endtabs %}

### End Save

The [EndSave](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfViewerControl.html#Syncfusion_Windows_PdfViewer_PdfViewerControl_EndSave) event occurs after the completion of the save operation. The [IsCanceled](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.EndSaveEventArgs.html#Syncfusion_Windows_PdfViewer_EndSaveEventArgs_IsCanceled) property of the [EndSaveEventArgs](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.EndSaveEventArgs.html) helps you to know whether the save operation is canceled or not. The following code shows how to wire the event in the [PdfViewerControl](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfViewerControl.html).
