Drawing Graphics Over Controls

[Genie.Jinesh]

I have this code for a custom listview, but when the selection box is drawn, it is drawn underneath the listviewitems. How would i draw it over the ListViewItems.

using System.ComponentModel;
using System.Drawing;
using System.IO;
using System.Windows.Forms;

namespace AlbumManager
{
public partial class Album : ScrollableControl
{

private int _Selection = 0;

private int _count = 0;

public Album()
{

AutoScroll = true;

InitializeComponent();

DoubleBuffered = true;

}

public Album(IContainer container)
{

AutoScroll = true;

container.Add(this);

DoubleBuffered = true;

InitializeComponent();

}

public int Selection
{
get
{
return _Selection;
}
set
{
_Selection = value;
}
}

public int Count
{
get
{
return _count;
}
set
{
_count = value;
}
}

public void AddAlbumImage()
{

OpenFileDialog _openFile = new OpenFileDialog();

_openFile.Filter = "Image Files|*.bmp; *.gif; *.jpg; *.png";

if (_openFile.ShowDialog() == DialogResult.OK)
{

Add(_openFile.FileName);

}

}

public void AddAlbumImage(bool Multiselect)
{

OpenFileDialog _openFile = new OpenFileDialog();

_openFile.Filter = "Image Files|*.bmp; *.gif; *.jpg; *.png";

if (Multiselect == true)
{
_openFile.Multiselect = true;
}

if (_openFile.ShowDialog() == DialogResult.OK)
{

if (Multiselect == true)
{

foreach (string _fileName in _openFile.FileNames)
{

Add(_fileName);

}

}
else
{

Add(_openFile.FileName);

}

}

}

_albumImage.Text = Path.GetFileNameWithoutExtension(FileName);
