Password Property in ConnectionManager

I'm developing a custom manager in SSIS that has several properties defined. One property is a password string that is visible in clear text in the properties pane. I'm trying to figure out how to create a masked field in the properties pane that will mask the text and not present this in clear text. Can someone send me instructions or code samples in C# for doing this? BOL doesn't provide any information on doing this.Hi,

we're facing the same problem, but haven't found any helpful information about it.

This post doesn't really help with the issue not displaying pwds as plain text.

Hope you guys can help.
