Getting the file size before upload sap.ca.ui.FileUpload

Hi All,

I am using sap.ca.ui.FileUpload . There is a getSize function which return the file size from the model . Is there a way to find it before upload so that upload could be stopped for above a set Threshold ? Currently as soon as plus button is pressed , upload starts .

Kindly suggest.
