Question

我有一个主要的应用程序，这里有边框不同的按钮。这还包括＆＃34; Einstellung＆＃34;按钮。按此按钮应显示与以前不同的内容。我用UserControl实现了这一点。

现在您可以在此用户控件中进行设置并保存它们。

我在设置中进行了这项保存

并使用代码

<TabControl HorizontalAlignment="Stretch" VerticalContentAlignment="Stretch" x:Name="tabControl">
    <TabControl.Resources>
        <LinearGradientBrush x:Key="LightBrush" StartPoint="0,0" EndPoint="0,1">
            <GradientBrush.GradientStops>
                <GradientStopCollection>
                    <GradientStop Color="#FFF" Offset="0.0"/>
                    <GradientStop Color="#EEE" Offset="1.0"/>
                </GradientStopCollection>
            </GradientBrush.GradientStops>
        </LinearGradientBrush>
        <SolidColorBrush x:Key="SolidBorderBrush" Color="#888" />
        <SolidColorBrush x:Key="WindowBackgroundBrush" Color="#FFF" />
        <SolidColorBrush x:Key="DisabledBackgroundBrush" Color="#EEE" />
        <SolidColorBrush x:Key="DisabledBorderBrush" Color="#AAA" />
        <SolidColorBrush x:Key="DisabledForegroundBrush" Color="#888" />
        <ControlTemplate x:Key="simpleTI" TargetType="TabItem">
            <Grid>
                <Border Name="Border" 
                            BorderThickness="0,0,0,2" 
                            Background="{StaticResource LightBrush}"
                            BorderBrush="{StaticResource LightBrush}" 
                            CornerRadius="0" >
                    <ContentPresenter x:Name="ContentSite" Margin="5,0"  VerticalAlignment="Center" HorizontalAlignment="Center"
                                          ContentSource="Header"  RecognizesAccessKey="True"/>
                </Border>
            </Grid>
            <ControlTemplate.Triggers>
                <Trigger Property="IsSelected" Value="True">
                    <Setter TargetName="Border" Property="BorderBrush" Value="#57B481" />
                </Trigger>
                <Trigger Property="IsEnabled" Value="False">
                    <Setter TargetName="Border" Property="Background" Value="{StaticResource DisabledBackgroundBrush}" />
                    <Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource DisabledBorderBrush}" />
                    <Setter Property="Foreground" Value="{StaticResource DisabledForegroundBrush}" />
                </Trigger>
            </ControlTemplate.Triggers>
        </ControlTemplate>
    </TabControl.Resources>


    <TabItem  MaxWidth="55" HorizontalAlignment="Center" Background="White" Template="{StaticResource simpleTI}" >
        <TabItem.Header>
            <TextBlock TextAlignment="Center" Text="Actions Needed" TextWrapping="Wrap" />
        </TabItem.Header>
    </TabItem>
    <TabItem  MaxWidth="55" HorizontalAlignment="Center" Background="White" Template="{StaticResource simpleTI}" >
        <TabItem.Header>
            <TextBlock TextAlignment="Center" Text="Actions Needed 1" TextWrapping="Wrap" />
        </TabItem.Header>
    </TabItem>
    <TabItem  MaxWidth="55" HorizontalAlignment="Center" Background="White" Template="{StaticResource simpleTI}" >
        <TabItem.Header>
            <TextBlock TextAlignment="Center" Text="Actions Needed 2" TextWrapping="Wrap" />
        </TabItem.Header>
    </TabItem>
</TabControl>

现在我按下＆＃34; Speichern＆＃34;按钮。他救了我的设置。我现在更改UserControl，所以我点击按钮＆＃34; Vorschau＆＃34;并向我显示一个新内容。如果我现在再次点击＆＃34; Einstellung＆＃34;是存在的内容，因为我已经存储了它。

但问题来了。我关闭了应用程序，然后再打开它。现在我点击按钮＆＃34; Einstellung＆＃34;在文本框中只有0位于其中。

不应该这样，但内容应该来自那里。

启动应用程序时检索此内容。请参阅代码段。

Vorschau.Properties.Settings.Default.BreiteBitmap = Int32.Parse(tbBreiteBitmap.Text);
Vorschau.Properties.Settings.Default.HoeheBitmap = Int32.Parse(tbHoeheBitmap.Text);
Vorschau.Properties.Settings.Default.AnzahlKoordinaten = Int32.Parse(tbAnzahlKoordinaten.Text);

AND

 public UCEinstellung()
        {
            InitializeComponent();

            //Lade der Einstellungen
            tbBreiteBitmap.Text = Vorschau.Properties.Settings.Default.BreiteBitmap.ToString();
            tbHoeheBitmap.Text = Vorschau.Properties.Settings.Default.HoeheBitmap.ToString();
            tbAnzahlKoordinaten.Text = Vorschau.Properties.Settings.Default.AnzahlKoordinaten.ToString();
        }

不幸的是，这不起作用。我希望你能告诉我错误在哪里。在另一个没有usercontrol工作的应用程序中，这个存储并正确检索。

Answer 1

看起来您只是分配属性而不是保存它们。您需要调用Save方法

Vorschau.Properties.Settings.Default.Save();

保存后，您可以在%userprofile%\appdata\local下找到该文件。有关详细信息，请参阅How to load a PKCS#12 Digital Certificate with Javascript WebCrypto API。

为此，设置范围应为“用户”。
