Solution 1

CheckState will return Checked, Unchecked, Indeterminate. But you need a Boolean value, so you look for the Checked Property, not the CheckState Property.

VB.NET

    For a = 1 To 5

       Dim bool As Boolean
       'assuming Cells(x) is a CheckBox
       bool = DataGridView1.Rows(a).Cells(0).Checked


       data(a-1) = bool.ToString
    Next

End Sub

then modify the code and make sure you are referencing a checkBox.
