Question

How can I raise an event while clicking a textbox? I’m having trouble finding references for events for WPF in C#.

The idea is to have textboxes fire an event when clicked. For example, let’s say as soon as I click a textbox, notepad is executed.

 private void textBox1_TextChanged(object sender, TextChangedEventArgs e)
 {
     hello = Process.Start("notepad");   
 }
 private void Click(object sender, MouseButtonEventArgs e)
 {    
     /* if (e.LeftButton == MouseButtonState.Pressed)
     {
         hello = Process.Start(@"notepad");                
     }*/           
 }

For text events use TextInput event and read entered character from e.Text

private void yourTextBox_TextInput(object sender, TextCompositionEventArgs e)
{  
    if (e.Text == "K")
    {
    }
}

for mouse events use MouseDown/MouseUp

Sometimes MouseDown/MouseUp won’t work on TextBox, then use this one:
