Hi Sean,
I have created a sample as per your directions and the "Save" BarItem from the MDI child form''s menu correctly replaces the "Save" BarItem in the main form''s menu. Note that the MergeType has to be set to ''Replace'' for both the BarItems. Please refer to the
test sample attached here and letme know if this meets your requirements. Thanks for your continued interest in Syncfusion products.
