*

* The textBox1s Text Binding will also get a BindingManagerBase

* and will use the following BindingContext form:

*

* bmb = BindingContext[dataSet, Number];

* The variable dataTable contains the Numbers table. Although

* the above DataGridView and TextBox are bound to this table using

* DataSource and DataMember form, they could have bound to the

* same Table (and data) by binding directly to dataTable as shown

* below. When doing this, DataGridView2 will use the following form

* of BindingContext:

*

* bmb = BindingContext[dataTable];

*

* The textBox2s Text Binding will use the following BindingContext

* form:

*

* bmb = BindingContext[dataTable];

*

* Therefore both dataGridView2 and textBox2 will share the same

* data source however they will not share the same CurrencyManager

* since they used different forms to specify their bindings.
