Custom SaveAs Dialog

So that to be complicated the life?

I understand that you wish to use radiobuttons to choose the format to keep, but the SaveDialog allows you to specify the elements that you wish to store in the drop-down list of formats.

[Visual Basic]
Protected Sub button1_Click(sender As Object, e As System.EventArgs)
    Dim myStream As Stream
    Dim saveFileDialog1 As New SaveFileDialog()

    saveFileDialog1.Filter = "txt files (*.txt)|*.txt|Bin files (*.bin)|*.bin"
    saveFileDialog1.FilterIndex = 2
    saveFileDialog1.RestoreDirectory = True

    If saveFileDialog1.ShowDialog() = DialogResult.OK Then
        myStream = saveFileDialog1.OpenFile()
        If Not (myStream Is Nothing) Then
            'Code to write the stream goes here
            myStream.Close()
        End If
    End If
End Sub

[C#]
protected void button1_Click(object sender, System.EventArgs e)
{
     Stream myStream ;
     SaveFileDialog saveFileDialog1 = new SaveFileDialog();

     saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.bin)|*.bin" ;
     saveFileDialog1.FilterIndex = 2 ;
     saveFileDialog1.RestoreDirectory = true ;

     if(saveFileDialog1.ShowDialog() == DialogResult.OK)
     {
         if((myStream = saveFileDialog1.OpenFile()) != null)
         {
             //Code to write the stream goes here.
             myStream.Close();
         }
     }
}

Another alternative that you have is to create your own window to save, and to invoke it when the user chooses the respective command.
