Hello, sorry for revive this post, I have a similar problem and don't found it on the forum.
I have a problem with the devexpress wrapper and DevEx.MaintenanceFormToolbar/BarManager.
I try to put some buttons on the Maitenance ToolBar ("MaintenanceFormTools") but when I close and open the designer it don't save the changes, then I created another toolbar, I set the property optionbar.usewholerow on false in the Maitenance ToolBar, created another toolbar and it allow me to put on this new toolbar buttons, but when I close and open the designer... again the property "usewholerow" is set to "true" and can't put the new toolbar on the same line, I try to inherit the maintenance bar manager and maintenance toolbar witout success, I cannot change the properties of the toolbar, and some errors appears.
I have to modify the source code and recompile or I have another option to change the "usewholerow" on the form designer?
I attached two images, one with usewholerow (bad) and one witout it (good, the one with usewholerow = false), the good example, when I close and open the designer, becomes bad again...
sorry for me bad english
and thanks guys for the great support
