Question

I have a window with the following elements, and I’m trying to access the value contained in <TextBlock Name="armingValue" but in my .xaml.cs file it doesn’t seem to be recognised.

What do I need to do to access the value?

<Window.Resources>
    <DataTemplate DataType="{x:Type ArmingVM:ArmingItem}">
        <CheckBox Margin="10,5" IsChecked="{Binding IsSet}" Content="{Binding Name}"/>
    </DataTemplate>
    <DataTemplate DataType="{x:Type ArmingVM:ArmingBindingData}">
        <DockPanel>
            <ItemsControl ItemsSource="{Binding ArmingItems}" HorizontalAlignment="Left">
                <ItemsControl.ItemsPanel>
                    <ItemsPanelTemplate>
                        <StackPanel Orientation="Vertical"/>
                    </ItemsPanelTemplate>
                </ItemsControl.ItemsPanel>
            </ItemsControl>
            <TextBlock Text="Enum Value: " HorizontalAlignment="Right"/>
            <TextBlock Name="armingValue" Text="{Binding Value}" HorizontalAlignment="Right"/>
        </DockPanel>
    </DataTemplate>
</Window.Resources>

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="193*" />
        <ColumnDefinition Width="551*" />
    </Grid.ColumnDefinitions>

    <Button Content="Get Panel Options" Name="btnGetOptionsConfigruation" Margin="12,12,23,396" Click="btnGetOptionsConfigruation_Click"></Button>

    <StackPanel Grid.Column="1" Height="325" HorizontalAlignment="Left" Margin="68,43,0,0" Name="stackPanel1" VerticalAlignment="Top" Width="438">
        <ItemsControl Name="armingItemsControl" ItemsSource="{Binding}"/>
    </StackPanel>
</Grid>

Answer 1

You do not need to access TextBox value but its binded value.
So considering that you have in XAML

 <TextBlock Name="armingValue" Text="{Binding Value}" HorizontalAlignment="Right"/>

You need to read a Value

Try always to avoid access UI elements directly in WPF, cause sometimes (not so rare cases) it becomes really tricky to find them if not imossible (I mean not guranteed way). Access a Data that stands behind them.
