问题描述

是否可以根据某些条件设置列表视图的ItemsSource. 我尝试了以下方法，但是没有用.

Is it possible to set the ItemsSource of a list view based on Some condition. I tried the following, but it didn't work.

   <ListView ItemsSource="{Binding FirstTypeOfSource}"  .....>
        <ItemsControl.ItemContainerStyle>
                <Style >
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding Category}" Value="All">
                            <Setter Property="ItemsSource" Value="SecondTypeOfCategory"/>
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </ItemsControl.ItemContainerStyle>
   </ListView>

有人可以帮忙找出解决方案吗?

推荐答案

这应该做到

    <ListView ItemsSource="{Binding FirstTypeOfSource}">
        <ListView.Style>
            <Style TargetType="ListView">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding Category}" Value="All">
                        <Setter Property="ItemsSource" Value="{Binding SecondTypeOfCategory}"/>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </ListView.Style>
    </ListView>
