I have tried : this._TextArea.setScrollTop(this._TextArea.getScrollHeight());
in every I update my textarea.
this is my code :
reqOpen.addEventListener("completed", function(e)
{
var isi = this._TextArea.getValue();
isi = isi + "\n" +mySentence+"\n"+ e.getData().getContent();
this._TextArea.setValue(isi);
this._TextArea.setScrollTop(this._TextArea.getScrollHeight());
}, this);
it doesn't work. any other step ?
