How to make control that is Hidden by default show up in the Visual Studio 2010 WPF designer?

I have a control that has Hidden visibility because it is bound to a property in the View Model whose default value causes it to be hidden. I can access it through the XAML but I'd like it still shown in the designer.

Is there a clean way of doing this? For now, I'm manually editing the Visibility attribute to make it show up, but I'd rather not have to do that, in case I forget to change it back.

You can bind to the boolean attached property DesignerProperties.IsInDesignMode, which is true only if you are inside the designer. Here is an example:

<Window x:Class="Visitest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:cm="clr-namespace:System.ComponentModel;assembly=PresentationFramework" 
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <BooleanToVisibilityConverter x:Key="conv"/>
    </Window.Resources>
    <Grid>
        <TextBox Margin="8" Background="Green" 
                 Visibility="{Binding (cm:DesignerProperties.IsInDesignMode), RelativeSource={RelativeSource Self}, Converter={StaticResource conv}}"/>           
    </Grid>
</Window>

Not sure it is a lot cleaner but you should set it to Visible in the ctor (before the Initialize);

Have you seen Hide WPF elements in Visual Studio designer? It looks like other people solved the issue by creating a simple custom extension.
