Basically I'm fairly impressed with, and a regular user of, the DevExpress comonents.

OriginalGriff is right: you should not have to handle the OnPaint event.

Is this someting you have introduced after altering your form to a ribbon form?

For a ribbon form there is a lot of painting and sizing stuff going on behind the scenes, and it usually works very well.

Try investigating the creation order of your components, or move them to an XtraPanel.

I would try searching the DevExpress forums for an answer, or post it as a new problem. They are usually very acommodating and responsive.

You don't need to do that in a Paint event - the PictureBox should hold the Image property and display itself as needed. You don't even need to Invalidate the PictureBox - the Image property setter should do that for you.

It is normal to set the Image property when the user decides which picture to show: Try removing your Rimage variable and referring to the PictureBox.Image property instead.
