3yr old daughter potty trained for over a year. . has been wetting panties for a week. no pain. is there an underlying issue? or is this common?

Check for UTI: Most likely if she has no fever, diarrhea etc it is not a urinary tract infection ( uti). Second concern would be juvenille diabetes. Third would be stress of some kind. She needs to have her urine tested by the pediatrician and a full exam.

Not unusual: Voluntary holding of urine is the most common cause of daytime wetting in young children. Often seen in 3- to 5-year-olds not taking the time to use the toilet. Sometimes skin irritation in the genital area is prevented by avoiding harsh detergents, bubblemaking products in the bathwater. Mild soap for bathing and can apply petroleum jelly to protect area. Avoid constipation. If persists, see dr.
