Failed to show Image datas in GridView

I am trying to show images (by parsing URL's) in GridView control. I am getting all other column values but not for "Icon" column where I want to show those images. I have a custom class that represent each colum. One property is named "Icon" and it is type Image (System.Drawing) and when I parse the object of the List of my class to GridView.DataSource I don't see anything within column Icon. Is there a normal way to show that in the control? I have been trying to find out on Bing/Google how to do it but without any success. Btw, I have filled every instance of my class inside List<MyClass> with every value.
