My dekstop application use a lot of .showdialog to open new form. Then it's necessary placing some method for the user who want close the popup form. I already using 'x' (close form, near minimize and maximize) in case user need to close the form.
Do i need adding exit/cancel/close in all popup form too ?

Answer
Yes. You do need a matching Cancel button to go with Save. If you don't, it may not be obvious how to close the dialog except via Save:
This is particularly the case where the other buttons such as the X are only coloured on hover — as appears to be the case here. It may be less important if the X is always red. However, you should also consider accessibility. A screen-reading application won't necessarily identify a way to close the dialog via system buttons, and if there is no Cancel button it may not react to the keyboard's Esc either.
