I developing WinForm using MDIParent (frmParent), one of my childform (frmchild1) have a usercontrol that if the user click a button from usercontrol, it would open up frmchild2 form. How do I code to make this work?

I try couple thing, but it still doesn't work like child2.MdiParent = frmParent.MdiParent;

Please advice.

thanks

The best way to do this would be to wire the user control up so rather than load a particular form it simply raises an event. Then frmChild1 can capture the event and it then knows who its MDI parent is and can open the second child form easily.

Alternatively use the UserControl.ParentForm to get the parent form (in this instance frmChild1) and then get its MdiParent property.

Oy, why are you asking the same question again. I've just spent time answering this question, then I remembered someone asking on similar, and it was you.

Don't waste my time by asking questions I've already answered, especially when it was you who asked them.
