Thank you for writing.
We have added the ability to open a SaveFileDialog
from a RadBrowseEditor
in our 2012 Q3 SP1
version. You can upgrade your Telerik controls to that or a newer version and you will be able to set a SaveFileDialog to be opened when a user click on the browse editor button.
I hope this will be useful. Should you have further questions, I would be glad to help.
