My advice would be to add the columns you want in grid in the designer. Add a text box column for id and a link column for Name, then set AutoGenerateColumns to False in code so no extra columns are generated. Note that you need to set the DataPropertyName of each column so it knows how to bind to the data source. You can then handle the CellContentClick event of the grid and maths the column index to the index of the link column.

I would also suggest that you add a BindingSource in the designer and then bind your DataTable via that. You can then get the current record from its Current property.

myBindingSource.DataSource = myDataTable
myDataGridView.DataSource = myBindingSource

and:

Private Sub myDataGridView_CellContentClick(...) Handles myDataGridView.CellContentClick
    If e.ColumnIndex = linkColumnIndex Then
        Dim url = CStr(DirectCast(myBindingSource.Current, DataRowView)("url"))

        'Use url as desirde.
    End If
End Sub
