Event for selecting Choice list entrys multiple time

Hi,

first of all, i want to apologize that i have no code or picture of the program right now, so i will try to explain it.

I have an GUI with an Table. In that table i have a choice list with a drop down menu. For example, if i select Choice 1, a inputdlgAlpha opens and i can type in something. If i select Choice 2 the inputdlgBeta opens and i can type is something. The program recognised the change from default to Choice 1 or to Choice 2 through the CellEdit callback. Now i want to select Choice 1 in the drop down menu and type in values, after that i want to select Choice 1 again and type in another values. But selecting Choice 1 again doesn't activate the CellEdit callback. If i use the CellSelection callback, something happens just by clicking the table, but not Choice 1 or Choice 2.

How can i work around that problem?

Hi,

The “CellEditCallback” is trigerred when the the content of a table cell is changed. Selecting ‘Choice 1’ or ‘Choice 2’ initially triggers this callback but not for the second time as content of the cell does not change.

You can try changing the content of the cell (with the drop-down menu) to something else like ‘Default’ whenever the user chooses an option. In this way, one can select the same option repeatedly as the content always reverts to ‘Default’. The below code example may help you understand this further :

fig = uifigure; 

myData = {'Andrew' 31 'Male' 'Choose'; ... 
'Bob' 41 'Male' 'Choose'; ... 
'Anne' 20 'Female' 'Choose';};

uit = uitable('Parent', fig, ... 
'Position', [100 150 380 100], ... 
'ColumnFormat',({[] [] [] {'Choice 1' 'Choice 2'}}), ... 
'ColumnEditable',true, ... 
'Data',myData); %last column has drop-down menus 

uit.CellEditCallback = @edit; 

function edit(obj,eventDetails) 

    value = eventDetails.EditData; 
    if strcmp(value,'Choice 1') 
    
        obj.Data(1,end) = {'Default'}; %Reverts Choice 1 to Default 
        answer = inputdlg('input 1:'); %Do something with the input 

    elseif strcmp(value,'Choice 2') 

        obj.Data(1,end) = {'Default'};  
        answer = inputdlg('input 2:'); 
    
    end 
end
