Hello,
even if I put MdiMergeable to false the toolbar steel hidden!!!
When the form is shown as non mdi child form (modal for example) the toolbar is shown.
Best regards
By default, the mdi child's toolbars manager will be hidden, because it merges its contents into the parent's manager instead of displaying itself. However, setting MdiMergeable to False on one or both toolbars managers should prevent this. If it is not, it may be a bug. I would recommend submitting the issue to the support group: http://es.infragistics.com/gethelp.
