I have found that
Me.DataBindings.Item(0).BindingMemberInfo.BindingField
gives me the name of the field a control is bound to.
Dim o As DataColumn = cols(Me.DataBindings.Item(0).BindingMemberInfo.BindingField)
gets me the column, or the field that I am looking for.
cols is passed to the method from the form's dataset.datatable (I guess).
Is there a way for a textbox to let it's findform produce these (dataset.datatable).cols?
