I need to make 1 button tha will create the Edit Text control and another button to remove it. I created the Edit Text using the code below:
% --- Executes on button press in pushbutton8.
function pushbutton8_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton8 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
eth = uicontrol('Parent', handles.uipanel5,'Style','edit',...
'String','Enter your name here.',...
'Position',[30 50 130 20]);
I need help with the code to remove it. Thanks.

A lot of the time you will find that setting Visible off on the control is better. Have your code set Visible 'on' when you want it to appear.
When you have a handle, you can use delete() of the handle to remove the control.

Follow-up question:
Using the code given, how can i access the eth handle if i want to use it on another callback?
I'm very new to matlab i'm not really familiar with handles.
