How to use contentmenustrip for listview and listviewitem? C#

I use Window Form C# My code

    private void ViewList_MouseClick(object sender, MouseEventArgs e)
    {
        if (e.Button == MouseButtons.Right)
        {

            Point pt = ViewList.PointToScreen(e.Location);
            ListViewItem item = ViewList.GetItemAt(pt.X, pt.Y);              
            if (item != null)
            {
                contextMenuStrip1.Enabled = true;
                contextMenuStrip1.Show(pt);
            }

   if(e.Buttons == MouseButton.Right)
          contextMenuStrip1.Show(e.X+val1, e.Y+val2);

val1 and val2 are integers values, if menu doesn't come to the right position you can add some values in it to make it on the right position :)

listView1.ContextMenu = yourcontextmenu;

or you can set it from properties window also
