Thank you for writing to us. I examined your snapshots and it seems you're using RadToolBars. If this is the case, then you can place them all in a RadToolBarTray so that they can resize accordingly when there isn't enough area where they can be displayed. This way the overflow button will be enabled to allow you to access the content that can't be displayed in the small area available for each ToolBar.
I attached a sample solution demonstrating this approach. Please have a look at it and let me know if it works for you or if I'm missing something.
