Disable WPF shortcut accelerator key (no underline text)

Question

I set the .Content value of the label for a string containing underscores; the first underscore is interpreted as an accelerator key.

Without changing the baseline (replacing all _ with __ ), is there a way to disable the accelerator for shortcuts?

Answer 1

If you use TextBlock as the contents of the label, its text will not accept underscores.

Answer 2

You can override the RecognizesAccessKey ContentPresenter property, which is in the default template for the label. For example:

 <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Grid> <Grid.Resources> <Style x:Key="{x:Type Label}" BasedOn="{StaticResource {x:Type Label}}" TargetType="Label"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Label"> <Border> <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="False" /> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </Grid.Resources> <Label>_This is a test</Label> </Grid> </Page> 

Answer 3

Use <"Text Block">"<"/Text Block"> instead of <"label"><"/label"> to print exact text with underline.

Answer 4

Why not?

 public partial class LabelEx : Label { public bool PreventAccessKey { get; set; } = true; public LabelEx() { InitializeComponent(); } public new object Content { get { var content = base.Content; if (content == null || !(content is string)) return content; return PreventAccessKey ? (content as string).Replace("__", "_") : content; } set { if (value == null || !(value is string)) { base.Content = value; return; } base.Content = PreventAccessKey ? (value as string).Replace("_", "__") : value; } } }
