Hi good evening,

I want make the content changes at Uipanel once user selected at popupmenu bar.

in here I set the code but how to make it changes according to user selected, the previous content will replace with new content at popupmenu selected: i'm using switch case for selected

contents = get(hObject,'String');
selected = get(hObject,'Value');
item_selected = contents{selected};
display(item_selected);
switch contents{selected}; 
case'Method 1'
    set(handles.edit25,'visible','on');
    set(handles.edit26,'visible','on');
    set(handles.popupmenu18,'visible','on');
case'Method 2'
    disp(handles.text25,'String','Hello')

like when user select method 1 at classification, the content in method 1 will show at "Result(uipanel)" space, and when user select method 2 at classification, the content in method 2 will show and content at method 1 will dissapear.

pls give me how to set the code to show it, I already try Visible "off" but its not working

Is your code in the appropiate callback? I think that in switch you should have the "selected variable", cause it should have the string selected, not an index. so..

selected = get(hObject,'Value');
switch selected,
case'Method 1'
    set(handles.edit25,'visible','on');
    set(handles.edit26,'visible','on');
    set(handles.popupmenu18,'visible','on');
case'Method 2'
    disp(handles.text25,'String','Hello');
end

Regards,

ya..its my code at appropriate callback.

Check that you are accesing fine to the two switch condition2. If not, maybe you have one or more blank space after 'Method 1' or 'Method 2'. If it's ok, try to add a "drawnow" command.

I hope this helps, regards
