I have a datagridview on a windows form, AllowUserToResizeColumns is set to false, it has 3 columns, as you'd expect i cant resize the columns, but i CAN resize the last column? I have column headers visible set to true, and i can drag the far end of the final column back n forwards. If i set column headers visible to false, then i have the ability to drag from the area where the rows are! Any idea why this is happening? I set AllowUserToResizeColumns to false cause i dont want my users to resize the columns as the name suggests, so why allow them to resize the last column?? Cheers
