using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WpfApplication1
{
public partial class UserControl1 : UserControl
{
public UserControl1()
{
InitializeComponent();
}
public Boolean bReadonly = false;

private void axPDFViewer1_OnDocumentOpened(object sender, AxPDFViewerLib._DPDFViewerEvents_OnDocumentOpenedEvent e)
{
if (bReadonly)
{
axPDFViewer1.SetReadOnly();
}
else
{

}
}

public void OpenEditable()
{
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.Filter = "PDF File Formats (*.pdf)|*.pdf|All Files (*.*) | *.* ||";
openFileDialog.RestoreDirectory = true;
openFileDialog.FilterIndex = 1;
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
axPDFViewer1.Toolbars = true;
axPDFViewer1.LoadFile(openFileDialog.FileName);
bReadonly = false;
}
}

public void OpenReadOnly()
{
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.Filter = "PDF File Formats (*.pdf)|*.pdf|All Files (*.*) | *.* ||";
openFileDialog.RestoreDirectory = true;
openFileDialog.FilterIndex = 1;
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
axPDFViewer1.Toolbars = false;
axPDFViewer1.LoadFile(openFileDialog.FileName);
bReadonly = true;
}
}

public void SaveAs()
{
axPDFViewer1.SaveCopyAs();
}

public void Print()
{
axPDFViewer1.PrintWithDialog();
}

public void ClosePDF()
{
axPDFViewer1.Clear();
}

private void UserControl1_Load(object sender, EventArgs e)

{
_host.OpenEditable();
}

private void Protect_Click_OnClick(object sender, RoutedEventArgs e)
{
_host.OpenReadOnly();
}

{
_host.SaveAs();
}

private void Print_Click(object sender, RoutedEventArgs e)
