>>>This is a newbie question. In my project I have a dataset file (MyDataSet.xsd, MyDataSet.Designer.cs, MyDataSet.cs). I need to add a couple of columns to this dataset. I double click on MyDataSet.xsd file in the VS Solution Explorer. I see the MYDATASET image with all the columns. I can right-mouse click and add a column. But how do I specify the type of the new column? In fact, I can't even figure out how to see the type of any of the existing columns.

Can you right click and hit properties?
