Hola Rathinagiri
Tratando de entender tu ejemplo con el "Create Event", hice lo siguiente: (pero no se si así es como deba funcionar)
* Siempre encuentra el primer registro "fer" pero existen 2
* Puse "ON INIT _ComboBoxAnywhereSearchInit( .f. )" para hacer la llamada a esta función // Pero da ERROR si pongo .T.
* Si pongo la propiedad SORT, me da ERROR
* En que momento se hace la llamada a la "funcion _ComboBoxAnywhereSearchClose( )"

Hello Rathinagiri
Trying to understand your example with the "Create Event", I did the following: (but not if this is how it should work)
* Always find the first record "fer" but there are two
* Put "ON INIT _ComboBoxAnywhereSearchInit (.f.)" To make the call to this function // But fails if I put .T.
* If you get the property SORT gives me ERROR
* At what point it is the call to "_ComboBoxAnywhereSearchClose() function"
