Hide specific TabItem in TabControl if not an admin

I am working with a TabControl in XAML,

however I only want certain TabItems to be available depending on the user.

Admins = 1 therefore should have full access to the TabControl,

Non admins = 0 therefore should only have specific tabs available.

How can I hide specific tabs depending on the user?

Thanks.

There are many ways of doing this, and I suppose which one you use depends on where the IsAdmin flag is stored

My personal preference is a DataTrigger which is based off a static User object which is set when the user first logs in

<Style TargetType="{x:Type TabItem}">
    <Setter Property="Visibility" Value="Collapsed" />
    <Style.Triggers>
        <DataTrigger Value="True" Binding="{Binding IsAdmin, Source={x:Static local:Settings.CurrentUser}}">
            <Setter Property="Visibility" Value="Visible" />
        </DataTrigger>
    </Style.Triggers>
</Style>

Settings would be a static class that contains a CurrentUser property that is set when the application starts up and the user logs in. CurrentUser has a boolean property called IsAdmin

Create a value converter:

[ValueConversion(typeof(bool), typeof(Visibility))]
public class BooleanToVisibilityConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        bool myValue = (bool)value;

        if (myValue)
            return Visibility.Visible;
        else
            return Visibility.Collapsed;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

Add this as a resource to your XAML:

 <local:BooleanToVisibilityConverter x:Key="visibilityConverter"></local:VisibilityConverter>

Assume that your property that shows if a user is admin named IsAdmin

<TabItem Visibility={Binding Path=IsAdmin, Converter={StaticResource visibilityConverter}}">

I think that is all.

You could hide all tabs once the application loads and then do something simple like the following to show each tab depending on the users access level:

if (userId == 1) {
  foreach (var item in tabControl.Items) {
    item.Visibility = Visibility.Visible;
}

} else if (userId == 0) {
   tabControl.Items[TableControlYouWantVisibile].Visibility = Visibility.Visible;
}
