[VB 2010] recupero valore di una cella di una datagrid

[gibra]

Puoi usare l'evento CellContentClick:

Private Sub DataGridView_CellContentClick(sender As Object, e As DataGridViewCellEventArgs) Handles dgv.CellContentClick
    Dim astring As String
    astring = CType(DataGridView.CurrentCell.Value, String)
    MessageBox.Show(astring)
End Sub
