I have a lot of datagrids in my application but there are few that doesn't accept any alignment settings which I don't understand at all, can't see any reason, I been looking through the options if there is anything but can't find anything. I just need one column of cells to be aligned to the right whatever I do all of the columns are aligned left and there is an option in the defaultcellstyle that is sat to middle left, but when I try to change it to Not Set it doesn't change.

It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
