Hi Sameh,

WinFormManager and WinToolbarsManager components together cannot be docked on to the same form. However you can have both the components in the same form, provided the WinToolbarsManager component is docked onto to a different container control. If the WinToolbarsManager component’s DockWithinContainer property is set to the form, then WinFormManager will disable itself and the WinToolbarsManager will take precedence.

For more information have a look at our help documentation:
