The following snippet results in showing "Clicked 2" twice if we inherit from Form2 which can't explain. Without overriding both "Click 1" and "Click 2" are shown.

   public partial class Form1 : TWForm
    {

        internal virtual void twButton1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Clicked 1"); 
        }

   public partial class Form2 : Form1
    {

...
        internal override void twButton1_Click(object sender, EventArgs e)
        {
            
            MessageBox.Show("Clicked 2"); 
        }
    }

Any idea how to achieve Foxpro behaviour to show "Click 2" just once or explain how it works or give a reference to explanation.


TIA
