how do i add an Image column in the datagrid for windows forms

I know the question was asked a while back but here's what I found from another forum. The code assumes that the images are stored in an ImageList.:

using System;

using System.Windows.Forms;

using System.Drawing;

 

namespace ImageColumnStyleTest

{

/// <summary>

/// Summary description for ImageColumnStyle.

/// </summary>

public class ImageColumnStyle : DataGridColumnStyle

{

private Image image = null;

public static ImageList imageList = null;

 

public ImageColumnStyle() : base()

{

}

 

protected override void Abort(int rowNum)

{

Invalidate();

}

 

protected override void Edit(CurrencyManager source, int rowNum, System.Drawing.Rectangle bounds, bool readOnly, string instantText, bool cellIsVisible)

{

}

 

protected override bool Commit(CurrencyManager dataSource, int rowNum)

{

return true;

}

 

protected override void Paint(System.Drawing.Graphics g, System.Drawing.Rectangle bounds, CurrencyManager source, int rowNum)

{

Paint(g, bounds, source, rowNum, false);

}

 

protected override void Paint(System.Drawing.Graphics g, System.Drawing.Rectangle bounds, CurrencyManager source, int rowNum, bool alignToRight)

{

Paint(

g,

bounds,

source,

rowNum,

Brushes.Red,

Brushes.Blue,

alignToRight);

}

 

protected override void Paint(Graphics g, Rectangle bounds, CurrencyManager source, int rowNum, Brush backBrush, Brush foreBrush, bool alignToRight)

{

int index = (int)base.GetColumnValueAtRow(source, rowNum);

InitImage(index);

 

Rectangle rect = new Rectangle(bounds.Location, imageList.ImageSize);

g.FillRectangle(backBrush, bounds);

g.DrawImage(image, rect);

}

 

protected override int GetPreferredHeight(Graphics g, object value)

{

return imageList.ImageSize.Height;

}

 

protected override int GetMinimumHeight()

{

return imageList.ImageSize.Height;

}

 

protected override Size GetPreferredSize(Graphics g, object value)

{

return imageList.ImageSize;

}

 

private void InitImage(int index)

{

if(imageList != null && imageList.Images.Count >= index + 1)

{

image = imageList.Images[index];

}

}

}

}
