save GUI figure to pdf

Hi,
I want to save the figure from GUI to pdf. Before saving I want to allow the user to choose the name and the folder where he wants to put the file. I try with this:
function Save_Callback(hObject, eventdata, handles)
% hObject handle to Save (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
orient landscape
file = uiputfile('*.pdf');
print(file, '-dpdf');
The problem is I cannot choose the destination path. The file is saved in the current folder only and one panel of my figure is missing.
How can I solve my problem?
Many thanks,
Dominika

try several overloaded methods for UIPUTFILE
[file path] = uiputfile('*.pdf');
print([path file], '-dpdf');
