How to get the row position in dataset from the datagrid 1

[mondi]

I am using Visual Studio .NET 2003. I have created a datagrid in a form, and I have bound it to a datatable of a dataset.
The datagrid at the begginning is sorted by one of the columns. At this point, is not difficult to find in which row of the dataset is found the data grid row that the user selects. But if he sorts the datagrid by another column of the datagrid, how can I find the exact row in dataset that he selects?
Thanks in advance for any help

A DataView object allows data binding on both Windows Forms and Web Forms.
Whenever data is displayed only one version of each row is displayed e.g Default, Original, Current, and Proposed. The displayed row is a DataRowView object that represents a customized view of a DataRow from the DataTable.
Let be
DataRowView selRow =...; // The selected row in the DataGrid control
DataRow dr = selRow.Row // Gets the DataRow from being viewed.

BindingManagerBase bm = dataGrid1.BindingContext(dataGrid1.DataSource, dataGrid1.DataMember);

DataRow dr = ((DataRowView)bm.Current).Row;
