I have a checkbox in a grid column. The column with the checkbox is ReadOnly. I have a sort method on the header for each column of the grid. When users click on the header, the grid data is resorted based on the header clicked. The resort works great on all columns except the one with the checkbox. It works fine unless the user first clicks on a checkbox and then tries to resort. When they do, the grid goes blank? [I am using SQL Server 7 for data]. If you don't first click on the checkbox in the grid, everything sorts fine in that column. Any ideas?

Thanks,
Doug
