Hi Shaik Asif,

Customizing call back functions and startupFnc helps to achieve the above task,

1)Edit the startup function of the app as

function startupFcn(app) 
            app.EditField.Value="Sample No : 01"; %initial value displayed
  end 

2)Edit the call back of the push button as

function ButtonPushed(app, event) 
            newStr = extractAfter(app.EditField.Value,": "); %extracting the sample number into string
            if newStr=="09" 
                app.EditField.Value="Sample No : 10"; 
            elseif newStr=="10" 
                app.EditField.Value="Sample No : 01"; 
            else 
                app.EditField.Value=replace(app.EditField.Value,newStr,"0"+num2str(str2num(newStr)+1)); %incrementing the sample number and updating it
            end    
end
