2. how do i give the ability to th开发者_开发问答e user in formview to enter true/false?

As the others said, you can use BIT datatype.

However, be warned that if you put BIT into a table, and you want only binary values, disable NULL.

If you allow NULL in a bit field it will actually be trinary and allow three values.

Use the BIT column. In your form just provide a radio button or checkbox. Here is a helpful link of Sql Data Types compared to .NET types: http://msdn.microsoft.com/en-us/library/cc716729.aspx

Use the bit datatype. I would use a checkbox in the gui. If it is not checked then the bit value should be 0, else 1.

One word: bit! (now I am just padding the answer because it is too short)
