You mention "code behind:" if this is ASP.NET then please tag your question to indicate that.

The easy way:
use a (class-) global status variable of type boolean.
Set this variable to true when you do not want the other event fired.
In Textbox1_Leave check this variable. If true, just return.

This would look like this

C#

private bool _noEvent = false;

protected Texbox2_KeyPress(object sender)
{
  _noEvent = true;

  // ... your other code
}

protected void Textbox1_Leave(object sender)
{
  if(_noEvent)
    return;
  
  // ... your other code
}
