Textbox not refreshing

Hi experts, good evening.

I'm using ContactsSaver to Delete/Save contacts to the phone's address book, but when I do it for a a lot of contacts, all the messages that I'm sending to a Textbox only appear after all the contacts have been updated..any ideas? Can I force a refresh on a control?

Best Regards,

Please show your relevant blocks

The Textbox is labelMensagem.
