Authorization Rules Noob question

Hello,

I have been using Rockys framework for a long time, but never needed the auth rules till now. I have a BusinessBase class that has the following code in it:

public string EnvironmentName

{

get
{
CanReadProperty(true);
return _environmentName;
}

set
{
CanWriteProperty(true);

if (_environmentName != value)
{
_environmentName = value;
PropertyHasChanged();
}

}

}

...

protected override void AddAuthorizationRules()

{
AuthorizationRules.AllowRead("EnvironmentName", "TestReader");
AuthorizationRules.DenyWrite("EnvironmentName", "TestReader");
}

I have an ReadWriteAuthorization control on the form that consumes this BO.

Ok, finally for the questions:

  1. When I change the textbox that is bound to the property, it allows the change in the textbox. Even though it throws an exception, nothing happens. I also am unable to end the application as long as there is a change to the textbox. It just keeps firing CanWriteProperty in BusinessBase and throws an exception. I would expect that the control would be readonly = true since I am in the TestReader role. Can anyone explain this?
  2. How can I get the textbox to not allow input since I am specifically Denied or at least have the original value roll back upon the exception that gets thrown??

Maybe I don't understand the AuthRules system as well as I thought I did. Any help is GREATLY apreciated.

 

Thanks,

-Jeff

Look through Chapter 9 to see how the Csla.Windows.ReadWriteAuthorization control is used to automatically enable/disable controls on a form based on the authorization rules in your object.

And, of course, look at the PTWin sample app code that's described in the chapter.

Rocky,

Tomorrow is another day. Maybe a fresh look at it again will help. I did read and use as reference the book (and PTracker). I may have just missed something. I'll post tomorrow either way.

Thanks for the heads up.

Jeff
