I am looking to see if I can do the following in WPF:
A user opens the WPF application and using the users AD name I will check the users role(s) in a custom DB. This will be something similar to asp.net membership db.
Depending on the user role the WPF will show certain controls.
So for example, if I was an Admin then I would have access to everything but if I was read-only user then I would have limited access to the application.
I know I can set the visibility using the following example:
public class RoleToVisibilityConverter : MarkupExtension,IValueConverter{
public RoleToVisibilityConverter()
{
}
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
var principal = value as GenericPrincipal;
bool IsValidUser = false;
if (principal != null)
{
foreach (String role in parameter.ToString().Split(';'))
{
if (principal.IsInRole(role))
{
IsValidUser = true;
break;
}
}
return IsValidUser ? Visibility.Visible : Visibility.Collapsed;
}
return null;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
public override object ProvideValue(IServiceProvider serviceProvider)
{
return this;
}
}
And in the XAML I add the following binding for visibility
Visibility="{Binding Source={x:Static systhread:Thread.CurrentPrincipal}, ConverterParameter=admin;editor;readonly, Converter={rv:RoleToVisibilityConverter}}But what I want to do is to not have to add this in xaml.
I would like to be able to get the users role and all of it's permissions and depending on the window load the UI permissions.
Reason is that I would like to be able to change what a read-only role can see/do without having to change the xaml.
Does anyone know if this is possible and if so is it best practice.
Thanks in advance.
