I'm setting the value of comboeditor on the EditorButtonClick event, but it causes my Valuechanged event to be fired twice.

        private void cbForecastNumbers_EditorButtonClick(object sender, Infragistics.Win.UltraWinEditors.EditorButtonEventArgs e)
        {
            this.cbForecastNumbers.Value = something;
            }
        }

        private void cbForecastNumbers_ValueChanged(object sender, EventArgs e)
        {
           //Alert
        }

Why is this happening?
