如何在Visual Studio 2012 C＃上更新我的数据源？

Question

I am working on a windows form application c# and I put spaces inside my database title fields which meant I had to go back and put an '_' whereever there was a space, eg "First_Name".

I done this but when I click refresh in the data source window in Visual studio it doesnt update the data set for some reason?

How do I update the data sets to have the titles include underscores in replace of the spaces?

Thanks
