Question

Answer 1

On C#:

textBox.Foreground = Brushes.Gray;

On XAML:

<TextBox Foreground="Gray" />

To disable it (will change background too):

textBox.IsEnabled = false;

Answer 2

The IsEnabled flag for a textblock does not grey the text. This post details the differences between textblock and label. It also shows the XAML to add a trigger on IsEnabled to grey the text.

Answer 3

You can set the TextBlock.Foreground property to any color (technically, any Brush). If you want it to be grayed out, just set:

<TextBlock Text="Foo" Foreground="Gray" />

If you want it to look "disabled", you can set IsEnabled to false:

<TextBlock Text="Foo" IsEnabled="false" />

Answer 4

TextBlocks do not grayout automaticly when disabled

you can use a style to do this for you

    <Style x:Key="DisableEnableTextBlock" TargetType="{x:Type TextBlock}">
    <Style.Triggers>
        <Trigger Property="IsEnabled" Value="True">
            <Setter Property="Opacity" Value="1" />
        </Trigger>
        <Trigger Property="IsEnabled" Value="False">
            <Setter Property="Opacity" Value=".5" />
        </Trigger>
    </Style.Triggers>
</Style>

Answer 5

The trouble with using the TextBox is that there's a box round it. If you use Label (with Content="Foo") then you can toggle the text colour with IsEnabled. Otherwise it behaves like TextBlock for a short heading/label.
