Thank you for contacting us.
I was not able to replicate the issue you experience. The PasswordChar property of RadTextBox seems to be working properly on my side. Would you please have a look at the attached project and let me know what I should modify in order to reproduce the issue.
In case you are using RadTextBoxControl
, the PasswordChar property has already been suggested as a feature request. Feel free to vote for it here: http://www.telerik.com/support/pits.aspx#/details/Issue=12265
I am looking forward to your reply.
