also tried to develop basic examples in BlackBerry but it requires a lot
to implement this simple Calculator example, where as here I was able to create this example in 10-15 minutes.

Code for button click event:
private void button1_Click(object sender, RoutedEventArgs e) { txtResult.Text = Convert.ToString(Convert.ToInt32(txtFirstNo.Text) + Convert.ToInt32(txtSecondNo.Text)); }
What do you think? Pretty cool, isn’t it?
