Hi Mikaël,
1. XPMenus.Bar in Statusbar mode can host only BarItems (and its derived objects) and cannot host any other Controls. If you wish to host custom controls in a status bar, then use a detached CommandBar with its DockState set to bottom as shown in the
sample attached here. Note that this approach will not support merging in a MDI scenario.
2. I am afraid, a desired size acnnot be set to the StaticBarItems, and they only resize themselves according to the length of the text contained in them.
Please let me know if you need any other information. Thanks for your interest in Syncfusion products.
