Hallo, I am building a GUI. I have used a popupmenu button with two options, for example(a,b). How can i callback the code which i have written in the random pushbutton_x when i select case "a" in my push button. Thanks.
Regards, Anush

Please explain the sentence "I am having trouble with calling this pushbutton1_callback with reference to my popupmenu's which i select." Include the code and mention, what trouble you have. Otherwise giving an answer is based on guessing only.

When a popup menu entry is selected, the callback of this uicontrol is called. You do not define a callback for the contents of the menu, but for the menu object only. The distinction of different code branches has to be implemented in the callback:
function popupmenuCB(hObject, EventData)
handles = guidata(hObject);
String = get(hObject, 'String');
Value = get(hObject, 'Value');
Selected = String{Value};
switch Selected
case 'a'
...
case 'b'
...
otherwise % No CASE without OTHERWISE
error('Unexpected switch')
end

After your comment: This is no valid Matlab syntax:
if (selectedIndex == 1);
else if (selectedIndex == 2);
h = msgbox('Operation Completed');
end
Either an "end" is missing, or you have to remove the space:
elseif (selectedIndex == 2);
% not: else if (selectedIndex == 2);
For: "How to call the push button operation here ??" Simply by calling the pushbutton callback:
pushbutton_Callback(hObject, eventdata, handles)
It is not used here, but adjusting the data might be better:
pushbutton_Callback(handles.pushbutton1, eventdata, handles)
or how your button is called in the struct. Use the debugger to determine this.
