Im new to C# and need a little help. I have tried googling, but to no avail so I'm asking here. I have WPF form with command buttons. And I use:

cmd_Button.Visibility = Visibility.Collapsed;
cmd_Button.Visibility = visibility.Visible;

To hide and show buttons as needed. The problem is that I have a lot of buttons and I have to collapse all(except three) at the initialization of the form and I have to collapse all except the ones I want to show on all Click events.

My question is; is there any way to collapse all buttons in a class, at the beginning of said class, and then show the ones i want to show with visibility.visible?

Here is an example of the code I am using:

<Button x:Name="cmd_Button1" Content="Button1" HorizontalAlignment="Left" Margin="15,96,0,0" VerticalAlignment="Top" Width="75" Click="cmd_Button1_Click"/>

and then c#

public MainWindow()
    {
        InitializeComponent();

        //collapse buttons

        cmd_Button1.Visibility = Visibility.Collapsed;
        cmd_Button2.Visibility = Visibility.Collapsed;
        cmd_Button3.Visibility = Visibility.Collapsed;
}

private void cmd_ShowButton2_Click(object sender, RoutedEventArgs e)
{
    cmd_Button1.Visibility = Visibility.Collapsed;
    cmd_Button3.Visibility = Visibility.Collapsed;

    cmd_Button2.Visibility = Visibility.Visible;
}

You could create a style in your page resource that defaults button visibility to collapsed:

 <UserControl.Resources>
     <Style TargetType="Button">
         <Setter Property="Visibility" Value="Collapsed" />
     </Style>
 </UserControl.Resources>

I would urge you to read up about MVVM though. WPF is far cleaner and simpler to use using MVVM bindings rather than manipulating ui elemenents in code behind.
