c# event and delegate question
- by user359562
I want to detach the custom event but could not detach. Please find below I am using -= to detach the event. I assume after this, TextChanged2 method should not be invoked as I have unregistered the event. Let me know if my understanding is wrong.
public delegate void TextChangedEventHandler1(object sender, TextBoxargs ta);
public event TextChangedEventHandler1 TextChanged1;
private void textBox1_TextChanged(object sender, EventArgs e)
{
this.TextChanged1 -= new TextChangedEventHandler1(TextChanged2);
TextChanged2(sender, e);
}
public void TextChanged2(object sender, EventArgs e)
{
textBox1.Text = textBox1.Text.ToUpper();
}
