How to show image in datagrid from database in wpf

private Image CreateThumbnailImage(Stream stream, int width)

{
    BitmapImage bi = new BitmapImage();
    bi.SetSource(stream);
 
    double cx = width;
    double cy = bi.PixelHeight * (cx / bi.PixelWidth);
 
    Image image = new Image();
    image.Source = bi;
 
    WriteableBitmap wb1 = new WriteableBitmap((int)cx, (int)cy);
    ScaleTransform transform = new ScaleTransform();
    transform.ScaleX = cx / bi.PixelWidth;
    transform.ScaleY = cy / bi.PixelHeight;
    wb1.Render(image, transform);
    wb1.Invalidate();
 
    WriteableBitmap wb2 = new WriteableBitmap((int)cx, (int)cy);
    for (int i = 0; i < wb2.Pixels.Length; i++)
        wb2.Pixels[i] = wb1.Pixels[i];
    wb2.Invalidate();
 
    Image thumbnail = new Image();
    thumbnail.Width = cx;
    thumbnail.Height = cy;
    thumbnail.Source = wb2;
    return thumbnail;
} 

Put that somewhere, then...

byte[] bytes = null;
//bytes you got from database
//bytes = something
	//200 or whatever you want the width to be.
CreateThumbnailImage(new System.IO.MemoryStream(bytes), 200));

maybe then something like this

datagrid1.items.add(imagehere);

Or you can use a view model view approach and bind the image, basically the hard part is done you now have the image.

The above method is something I found here:

There are other ways but this way is geared towards silverlight, for lower memory consumption, I took a wild guess that you are probably using silverlight.
