Question

What is the equivalent Following code in wpf

code in winapp :

 private void textBox1_Enter(object sender, EventArgs e)
{
    MessageBox.Show("www.stackoverflow.com");
}

Answer 1

There is no Enter event on a WPF textbox – you could use the GotFocus event to the same effect though.

private void textbox1_GotFocus(object sender, System.Windows.RoutedEventArgs e)
{
    MessageBox.Show("www.stackoverflow.com");
}

this is accessed in the XAML as follows:

<TextBox GotFocus="textbox1_GotFocus"/>
