How to retain password after postback?

[El]

it is a very simple scenario. I have a RadTextBox in Password mode which is nested in RadMultiPage.
When i click a checkbox with enabled AutoPostback AJAX loading panel appears and the password field is empty.
As you see i have a RadAjaxManager. Otherwise i would simply say:

If IsPostBack Then
     If Not String.IsNullOrEmpty(Password.Text.Trim()) Then
         Password.Attributes.Add("value", Password.Text)
     End If
     If Not String.IsNullOrEmpty(ConfirmPassword.Text.Trim()) Then
         ConfirmPassword.Attributes.Add("value", ConfirmPassword.Text)
     End If
 End If

Thank you

Hello El,

Their has been a long discussion about this on the Input forum and their is no way to persist the password in a RadTextBox or a standard asp TextBox when they are in password mode because that is the nature of the control.

I disagree with you. If i am not using RadAjaxManager it works perfectly fine with the code i posted previously.
It seems that AJAX environment has a diff rules guessing that i should use another Event handler to put this hack to. 
I hope that one of the telerik admin will send solution soon. 

Thanks
