Issue using AutomationProperties with NumericUpDown control.

[treos33]

Hello,

This is my first project with WPF and Mahapps so I'm not sure if this is a bug or user error but any help would be appreciated.

I have several NumericUpDown controls where I'm binding their AutomationProperties.Name and AutomationProperties.HelpText as follows:

<mah:NumericUpDown
    Grid.Column="1"
    Width="{Binding ScaledWidth}"
    Margin="10,10,0,0"
    AutomationProperties.HelpText="{Binding HelpText}"
    AutomationProperties.Name="{Binding Label}"
    HideUpDownButtons="False"
    IsReadOnly="{Binding IsReadOnly}"
    Maximum="{Binding MaxValue}"
    Minimum="{Binding MinValue}"
    NumericInputMode="{Binding NumericInputFormat}"
    TextAlignment="Left"
    ToolTip="{Binding HelpTip}"
    Value="{Binding DblValue}">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="GotFocus">
            <i:InvokeCommandAction Command="{Binding DataContext.SelectedFieldChangingCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}" CommandParameter="{Binding}" />
        </i:EventTrigger>
        <i:EventTrigger EventName="LostFocus">
            <i:InvokeCommandAction Command="{Binding DataContext.SelectedFieldChangingCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}" />
        </i:EventTrigger>
    </i:Interaction.Triggers>
</mah:NumericUpDown>

However, these properties aren't working with my screen reader. I think the reason it's not working is that the properties are being set on the NumericUpDown Control, but when the control get's focus, it's actually forwarding the focus to the TextBox which doesn't have any AutomationProperties assigned.

Is there a way for me to assign the AutomationProperties of the TextBox within the NumericUpDown, or better yet, have the TextBox inherit those properties from the NumericUpDown?

Thanks!
