Private Sub button1_Click(sender As Object, e As EventArgs)
Try
' Get the 'BindingManagerBase' object.
Dim myBindingManagerBase As BindingManagerBase = BindingContext(myDataTable)

Remarks
The RemoveAt method relies on the underlying data source to determine how the method behaves. (See the Binding class for a list of supported data sources.) For classes that implement IList, IBindingList, or ITypedList, as well as strongly typed classes that implement IList, the RemoveAt method actually deletes the row in the underlying list instead of removing its contents.
If the underlying list implements the IBindingList interface, the AllowRemove property must return true. If the underlying list implements the IList interface, the IsFixedSize property must return false.
