This is a great control. But there are something bad when we create an application on it and fill the image in cells. The image will fill all of the space in the cell.
I change the code of the CellType.cs like this:
if (Image != null)
dc.Graphics.DrawImage(Image, new Rectangle(0, 0, Image.Width, Image.Height));
Maybe there are more params like anchor, scale could be added to ImageCell. Thanks.
