c# - 将自定义模板添加到 ListView - GridView WPF？

Question

我目前有这个 XAML 代码：

<ListView x:Name="listFeedSearch" Margin="-548.856,95.333,0,7.667" 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=" " x:Name="listFeedSearchSelect" />
        </GridView>
    </ListView.View>
</ListView>

我想要做的是listFeedSearchSelect在每条记录的单元格中都有一个按钮。

我试图做的是，但没有奏效，它所做的只是显示为空单元格：

<GridViewColumn Header=" " Width="100" x:Name="listFeedSearchSelect">
    <GridViewColumn.CellTemplate>
        <DataTemplate>
                <Button Content="Select" />
        </DataTemplate>
    </GridViewColumn.CellTemplate>
</GridViewColumn>

谁能帮帮我，谢谢。

尝试将您的模板设置为资源。像这样：

<Window.Resources>
    <DataTemplate x:Key="SelectButtonColumnDataTemplate">
        <Button Content="Select" Command="{Binding SelectItemCommand}" />
    </DataTemplate>
</Window.Resources>

<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>

如果我只是复制并粘贴GridViewColumn你的，并且集合中有项目，它确实会按预期显示一个按钮。问题可能出在您的上下文中。
