如何访问按钮的绑定值

Question

我有以下XAML

<Window.Resources>
    <DataTemplate x:Key="SelectButtonColumnDataTemplate">
        <Button Content="Select" Command="{Binding SelectItemCommand}" Click="SelectButtonClick" />
    </DataTemplate>
</Window.Resources>
<Grid x:Name="LayoutRoot">
<ListView x:Name="listFeedSearch" HorizontalAlignment="Left" Width="542.5" RenderTransformOrigin="0.5,0.5" ItemsSource="{Binding SearchCollection}">
    <ListView.RenderTransform>
        <TransformGroup>
            <ScaleTransform/>
            <SkewTransform/>                
            <RotateTransform/>                
            <TranslateTransform/>            
            </TransformGroup>        
            </ListView.RenderTransform>        
    <ListView.View>            
        <GridView>                
            <GridViewColumn Width="150" Header="Feed Name" x:Name="listFeedSearchName" DisplayMemberBinding="{Binding FeedName}"  />                
            <GridViewColumn Width="280" Header="Feed Address" x:Name="listFeedSearchAddress" DisplayMemberBinding="{Binding FeedUrl}" />                
            <GridViewColumn Width="100" Header=" " CellTemplate="{StaticResource SelectButtonColumnDataTemplate}" />            
        </GridView>        
        </ListView.View>    
</ListView>     
</Grid>

添加以下事件处理程序：

private void SelectButtonClick(object sender, RoutedEventArgs e)
        {
        }

我想做的是输出行的单个绑定值。

我该怎么做，我知道这是一个类似的东西

var data = (sender as Button)...

感谢

Answer 1

如果您将CommandParameter按钮设置为(感谢Bolu(：

"{Binding}"

那么下面的代码将检索当前单击的对象并显示一个消息框。其中，foo是用于填充gridview 的类

 public class foo
 {
    string FeedName {get;set;}
    string FeedUrl {get;set;}
 }
 public void InitialiseListView(List<Foo> Items)
 {
    listFeedSearch.ItemsSource = Items;
 }
 private void SelectButtonClick(object sender, RoutedEventArgs e)
 {
    foo b = (foo)(sender as Button).CommandParameter;
    string s = string.format("Name: {0} URL: {1}",b.FeedName,b.FeedUrl);
    MessageBox.Show(s);
}

如果我理解正确，您需要使用{Binding}:Xaml:Binding到当前DataContext

参考：理解WPF绑定命令参数="；｛绑定｝"；
