You will have to hard-code this functionality. You will need to create a pushbutton and then under that new pushbutton function you will have to use "set" to restore all your edit boxes back to blank space or a default value. I.e.,

set(handles.my_edit_box,'String','');

or

set(handles.my_edit_box,'String','some_default_value');

If there are a lot of edit boxes, you could set the Tag property on each edit box and use FINDOBJ to change the value of all these controls

Walter Roberson 2011-12-13

Well, findobj to locate the boxes whose String is to be set

set(findobj('Tag','ResetAllowed'),'String',{''})

This will, however, not work if you are using GUIDE, as GUIDE uses the Tag property for other things.

set(findobj(0,'style','edit'),'string','')  %put this in the button callback
%that should clear all edit uicontrols

or

set(findobj(handles.figure1,'style','edit'),'string','')
%should only clear the edit uicontrols from the current GUI

Thanks .. Elige Grant & Paul Peeling

Grateful to you :)

OK..

 What About this code , How do I take advantage of it ?
    closeGUI = handles.figure1; %handles.figure1 is the GUI figure
  % guiPosition = get(handles.figure1,'Position'); %get the position of the GUI
  % guiName = get(handles.figure1,'Name'); %get the name of the GUI
  % eval(guiName) %call the GUI again
  % 
  % close(closeGUI); %close the old GUI
% set(gcf,'Position',guiPosition); %set the position for the new GUI
