如何在WPF中根据运行时ComboEdit的选定值更改控件的位置？

标签： .net wpf wpf-controls devexpress dynamic-controls

enter image description here我有一个ComboEdit，其中显示了国家/地区列表。在表单上，​​它们是一个ADDRESS选项卡，在选择ComboEdit值时设置为激活。控件在ADDRESS选项卡上的位置必须根据指定的布局进行更改（我们可以在此使用Databsase根据所选国家/地区存储布局）。

我想显示地址格式＆amp;根据comboedit选择的公司指定的每个订单的动态控制。请参阅不同的地址格式：http://msdn.microsoft.com/en-us/library/cc195167.aspx。

我想根据所选国家/地区更改控件的更改位置。有什么建议/想法吗？ 目前我正在使用两个不同的网格，并根据国家/地区值进行可见/隐藏。对于一个或两个国家/地区来说这是可以的，但是无法添加那么多网格，因此希望将其存储到数据库中。请建议我正确的方法......！

作为Grid中的所有控件。如何根据所选国家设定位置？

帮助感谢！ 谢谢！

嗯，我不知道为你提供以下建议是否为时已晚，但我更倾向于使用不同的虚拟机（每个可能的国家一个）来反映地址数据。然后，您可以为每个可选国家/地区创建DataTemplate（每个地址vm一个）。您需要的下一个是TemplateSelector，根据传递给它的VM选择正确的DataTemplate。

这意味着，如果根据ComboBox中所选国家/地区更改了地址VM，则TemplateSelector会选择相关的DataTemplate。通过这种方法，您可以根据需要轻松扩展其他国家/地区的应用程序。

请注意，此解决方案尊重MVVM模式（不确定您是否正在使用它），并且上面的文字只是我对如何实现此类要求的想法的描述。在成功之前，您可能必须解决一些问题。

以下是更改两个标签的显示顺序的示例

<强> XAML 

<Window x:Class="WpfApplication1.JsonWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="JsonWindow" Height="300" Width="300"
        >
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <TextBlock Text="Label 1" Grid.Row="{Binding label1}"/>
        <TextBlock Text="Label 2" Grid.Row="{Binding label2}"/>
        <Button Content="Change Position" Click="Button_Click" Grid.Row="2"/>
    </Grid>
</Window>

代码背后 

public partial class JsonWindow : Window, INotifyPropertyChanged {
    public JsonWindow() {
        InitializeComponent();
        this.DataContext = this;
        label1 = 0;
        label2 = 1;
    }

    public int label1 {get;set;}

    public int label2 { get; set; }

    private void Button_Click(object sender, RoutedEventArgs e) {
        label1 = 1;
        label2 = 0;
        PropertyChanged(this, new PropertyChangedEventArgs("label1"));
        PropertyChanged(this, new PropertyChangedEventArgs("label2"));
    }

    public event PropertyChangedEventHandler PropertyChanged;
}

但正如 @Novitchi S 所说，你将不得不取消你的边缘技术。使用Grid.Row和Grid.Column。
