disable event handler in c# on textchanged

Question

I want to be able to disable or enable textchanged event when I need to. I have made my function, but I need to dismiss event handler, how can I do that?

Here is my code:

private void textBox1_TextChanged(object sender, EventArgs e)
{
           //something
}

Answer 1

This to add the event

textBox1.TextChanged += new TextChangedEventHandler(textBox1_TextChanged);

this to remove the event

textBox1.TextChanged -= new TextChangedEventHandler(textBox1_TextChanged);

Or just the method name

This to add the event

textBox1.TextChanged += textBox1_TextChanged;

this to remove the event

textBox1.TextChanged -= textBox1_TextChanged;

Hope it helps.

Answer 2

simply un-register the event

 yourEvent-= YourFunction

and if you want to register again

 yourEvent+= YourFunction
