Hello Niranjan

Assuming that you have defined an event MY_EVENT in your class you can define within the same class an event handler method, e.g. HANDLE_MY_EVENT. In order to do so go to the Properties tab when creating the method and mark checkbox "Eventhandler for". Enter your class and the event (e.g. MY_EVENT).

Finally, you have register the event handler method, e.g. in the CONSTRUCTOR:

  SET HANDLER handle_my_event FOR me.

To raise the event you need the following coding in one of your class methods:

  RAISE EVENT my_event.

For comparison, have a look at class <b>CL_GUI_ALV_GRID</b>. The instance method <b>CHECK_DATA_CHANGED</b> raises <b>event DATA_CHANGED</b> if values on an editable ALV grid have been changed. The method is usually called at PAI of the dynpro displaying the ALV grid.

hi,

create a class in se24.

<b>click the <b>EVENTS</b> tab, define an event.</b>

<b>click the <b>METHODS</b> tab, define a method to trigger/ raise the event</b>

<b>define one more method as an event handler method for the event.</b>

for a method to be an event handler, click on the detail view,

select the check box <b>Event Handler for</b> give the classname where the event is defined and the event name, click on Change button.

<b>event can be in the same class or different from that of the event handler method.</b>

don't forget to <b>register the event handler method in the program.</b>

click the code button of ur trigger method(meth2 in my example) and write there,

raise event evt1.

now your class is ready.

now in se38 program,

declare a reference variable to ur class,

create an object,set the handler for ur event,

call the trigger method

<b>data:oref type ref to zsowcl1.

create object oref.

set handler oref->meth1 for oref. handler method

call method oref->meth2. raise evnt method</b>

hope it gives you clear idea,

Regards,
