This event provides an opportunity to handle errors effectively by allowing developers to log the details or display appropriate messages to users when an issue arises within the PdfViewerControl.

C#

public Form1()
{
    InitializeComponent();
    PdfViewer.ErrorOccurred += PdfViewer_ErrorOccurred;
}

private void PdfViewer_ErrorOccurred(object sender, ErrorOccurredEventArgs e)
{
    // Log error message
    Console.WriteLine("Error occurred in PdfViewerControl: " + e.Message);

    // Display error message to the user
    MessageBox.Show("An error occurred while viewing the PDF: " + e.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
