WPF中DataTrigger不响应问题

正确的代码：

<TreeView
            Grid.Row="2" 
            Grid.RowSpan="4"
            Grid.Column="1" 
            Grid.ColumnSpan="2">
            <TreeView.Style>
                <Style TargetType="TreeView">
                    <Setter Property="Visibility" Value="Visible"/>
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding IsChecked,ElementName=BtnDatabase}" Value="false">
                            <Setter Property="Visibility" Value="Collapsed"/>
                        </DataTrigger>
                        <!--<Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Background" Value="Wheat"/>
                        </Trigger>-->
                    </Style.Triggers>
                </Style>
            </TreeView.Style>                       
        </TreeView>

错误的代码：

<TreeView
			visibility="visible"
            Grid.Row="2" 
            Grid.RowSpan="4"
            Grid.Column="1" 
            Grid.ColumnSpan="2">
            <TreeView.Style>
                <Style TargetType="TreeView">
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding IsChecked,ElementName=BtnDatabase}" Value="false">
                            <Setter Property="Visibility" Value="Collapsed"/>
                        </DataTrigger>
                        <!--<Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Background" Value="Wheat"/>
                        </Trigger>-->
                    </Style.Triggers>
                </Style>
            </TreeView.Style>                       
        </TreeView>

解释：

‘猜测原因，是控件的属性设置有比style中属性设置更高的优先级，所以在控件中已经设置的属性，如果再在style中进行设置将无效’
