If you use GUIDE and double click your text edit box you'll bring up the property inspector. In there you'll see a callback for the key press function. Click the icon for that to go to the code for that. In there, get the text from the edit box and do something with it, such as display it in a static text label:

editTextString = get(handles.editText, 'String');
set(handles.staticText, 'String', editTextString);

This seems like the standard for uicontrol of type edit. Please explain exactly, what you mean by "text box".

Perhaps you mean a text object (see "help text"), which is updated by the WindowsKeyPressFcn, which is a property of the parent figure.

yes it is a uicontrol of type edit

if i type any letters in edit text box i need to display the same letters without pressing enter key
