Presumably because rows[1]["AttributeValue"] isn't a FormWindowState.
What is is it, actually?

Print out rows[1]["AttributeValue"].GetType() to find out.

You can't cast from a string to FormWindowState - although you could
use Enum.Parse to get a value.

Yup.

You can put anything you like in a dataset. When you create the column,
put in the type that you're interested in - in this case,
typeof(FormWindowState).

Of course, you won't be able to put a FormWindowState into an actual
database directly - you'd need to convert to either an int
representation or a string representation.

What do you mean by that? Sorry, I don't understand.

You can store it as FormWindowState, using typeof(FormWindowState).
