Answer 1

I know this is a really old question.. and it appears it was answered.. But I got here with the same question but a different reason for the question, and so a slightly different answer worked for me. I have a nice reusable generic datagridview that takes the datasource supplied to it and just displays the columns in their default order. I put aliases and column order and selection at the dataset's tableadapter level in designer. However changing the select query order of columns doesn't seem to impact the columns returned through the dataset. I have found the only way to do this in the designer, is to remove all the columns selected within the tableadapter, adding them back in the order you want them selected.
