带有科学符号的GridView中的DataTable（ASP .NET 4.0）

Question

I have a problem, that I was hoping you could help me solve.

I have this DataTable that I want displayed in a GridView. That itself is not a problem. The problem is that I would very much like it displayed with scientific notation. It is also using "," as decimal seperator, which I would like to be "." instead.

In short: I would like to go from "xxxxxx,xxxxxx" to something like "xx.xxexxx".

The DataTable contains 9 values. It's a 3x3 matrix I have received after calling a Matlab function (output type MWNumericArray). I'm not even sure converting it to DataTable was the right choice in the first place.

Thanks in advance!

EDIT: BTW I'm very new to C#!

But it's quite simple to do from Visual Studios.

1. Right click the datagridview and select edit columns
2. Go to Appearance -> DefaultCellStyle
3. Then under CellStyle builder, under Behavior click edit on Format
4. Select scientific
