Gridview contains one image column and one text column. It is supposed that the data in the gridview is sorted by the text column. EnableSorting is enabled for the whole gridview. The image column has AllowSort disabled and SortOrder set to None whereas the text column has the SortOrder set to Ascending. However, if the grid is populated with data it is primarily sorted by the image column. 
This problem is illustrated in the attached project. I've added three rows with data and would expect the grid be sorted as "A", "B", "C", whereas the resulting order is "B", "C", "A" due to the image in the row which contains the "A".
