But not without compromising consistency. If I drop this approach, I will have to remove the Password property from the IDataErrorInfo Implementation and on Login button click will have to verify it, presenting the user with a message box. I am sure, this problem is happening because the Password property has got extended by the helper class. Needless to say that the ff in the above code stands for the namespace reference: xmlns:ff="clr-namespace:MyProject.UserViews" These issues often take the form of a pixellated screen, blurry or static images and abnormal behavior from. But the "Enter password" message that I did set as a part of this property validation is not being rendered by the Content presenter that lies below the PasswordBox. Reset Admin Password Dahua XVR1B04H, XVR1A08. We can expose the UnsecurePasswordBox.Password string as a DependencyProperty which lends itself nicely to the MVVM paradigm. This is potentially also a disadvantage see below. The property is getting validated as my "Login" button is not getting enabled without the user filling in password. We would still need to extend the default PasswordBox style with the ability for a 'reveal button', but that could be done using an internal attached property.

PasswordBox does not provide "Password" as dependency property. Unfortunately, login forms demand password (and subsequently PasswordBox). If you have read the above code, you might well have guessed that I am trying to create a login form. The default ErrorTemplate of the textbox (a red boundary that appears around it) is replaced by a new error template in which a content presenter placed just below the text box will convey the error to the user - certainly a superior and more elegant template. Here is the data template that he uses to show the error: Ī working sample of this data template getting consumed is as follows: I have always admired the way Josh Smith has built his sample application.Īnd I have also tried to emulate the way in which the ViewModels of his application implements the IDataErrorInfo property and through a custom DataTemplate renders the errors before the user.
