WPF中的访问类数据导航？ [英] access-like data navigation in WPF?

问题描述

如果您建立一个用户控件（甚至是自定义的），那么建立数据导航的最佳方法就是像在XAML / C＃控制），我刚刚绑定到我的集合，其中我可以把其他控件？ （因此这个问题：可以使用C＃用户控制包含其他控件（使用它时））

或者可以通过派生出ItemsControl来构建东西吗？如何？

或者今天做的完全不一样（像去年这样的导航风格）？

我比较新的C＃和所有（不是这样编程，但更像家庭主妇语言Access-VBA）我也不是英文的本地人。您可以创建用户控件并放置一堆按钮（第一，上一页，下一页，最后一页）

解决方案

，等等），并将其放在主窗口上。其次，您可以将数据导航用户控件绑定到一个 CollectionViewSource ，这将有助于您在数据之间导航。

您的主窗口：

 < Window.Resources> 
< CollectionViewSource x：Key =itemsSource ={Binding}/> 
< /Window.Resources> 
< Grid> 
< WpfApplication1：DataNavigation DataContext ={Binding Source = {StaticResource items}}/> 
< StackPanel> 
< TextBox Text ={Binding Source = {StaticResource items}，Path = Name}/> 
< / StackPanel> 
< / Grid> 
  

您的数据导航用户控制：

 < StackPanel> 
< Button x：Name =PrevClick =Prev_Click>& lt;< / Button> 
< Button x：Name =NextClick =Next_Click>& gt< / Button> 
<！ - 等等 - > 
< / StackPanel> 
  

您的点击处理程序如下所示：

  private void Prev_Click（object sender，RoutedEventArgs e）
 {
 ICollectionView view = CollectionViewSource.GetDefaultView（DataContext）; 
 if（view！= null）
 {
 view.MoveCurrentToPrevious（）; 
} 
} 
  

希望这有帮助。

What would be the best way to build a data-navigation like in access-forms in XAML/C#?

Should I build a user control (or even custom control) that I just bind to my collection in which I can put other controls? (hence this question: C# User Control that can contain other Controls (when using it) )

Or can I build something by deriving from then ItemsControl somehow? how?

Or would this be done completely different today (like "this style of navigation is so last year!")?

I'm relatively new to C# and all (not programming as such, but with more like "housewife-language" Access-VBA) also I'm no native english speaker. So pls be gentle =)

解决方案

You can create user control and place a bunch of buttons (First, Prev, Next, Last, etc..) in it and place it on the main window. Secondly, you can bind your data navigation user control to a CollectionViewSource which will help you to navigate among your data.

Your main window:

<Window.Resources>
    <CollectionViewSource x:Key="items" Source="{Binding}" />
</Window.Resources>
<Grid>
    <WpfApplication1:DataNavigation DataContext="{Binding Source={StaticResource items}}" />
    <StackPanel>
        <TextBox Text="{Binding Source={StaticResource items},Path=Name}" />
    </StackPanel>
</Grid>

Your Data Navigation User Control:

<StackPanel>
    <Button x:Name="Prev" Click="Prev_Click">&lt;</Button>
    <Button x:Name="Next" Click="Next_Click">&gt;</Button>
    <!-- and so on -->
</StackPanel>

And your click handlers goes like this:

private void Prev_Click(object sender, RoutedEventArgs e)
{
    ICollectionView view = CollectionViewSource.GetDefaultView(DataContext);
    if (view != null)
    {
        view.MoveCurrentToPrevious();
    }
}

I hope this helps.
