How to call callback the code through the selection of push button

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

What is a "popupmenu button"? Eitehr it is a popup menu or a button. "example(a,b)" is not clear also. What is "the random pushbutton_x"?

Hello jan, I am reading a data from a .xls file and making some calculations. This calculations i am doing it under a pushbutton1_callback. Similarly i have a different set of calculations in the same pushbutton1_callback. Finally Now i am interested in performing this set of calculation with the use of popupmenu_callback for an example if i select case "a" and press my pushbutton1 certain set of calculation has to perform. if i select case "b" and press my pushbutton1 the other set. I am having trouble with calling this pushbutton1_callback with reference to my popupmenu's which i select.

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.

% --- Executes on selection change in popupmenu.
selectedIndex = get(handles.popupmenu, 'value');
    % Take action based upon selection

      if (selectedIndex == 1);  
       %%%%%%How to call the push button operation here ?? %%%%%%%%     

      else if (selectedIndex == 2);
  %          pushbutton_Callback; 
           h = msgbox('Operation Completed');

      end

% --- Executes on button press in pushbutton.
function pushbutton_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

f = figure;
data = xlsread('abc.xlsm','Data','C7:F23');
t = uitable(f);
display(data);

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.
