WPF中listbox点击时，整个背景变成蓝色，怎么让整个背景不变色，只是让单个模块获取焦点？

模板应该能解决你的问题

重写模板

						</ControlTemplate.Triggers>
					</ControlTemplate>
				</Setter.Value>
			</Setter>
		</Style>
	</Window.Resources>

	<Grid x:Name="LayoutRoot">
		<ListBox HorizontalAlignment="Left" Margin="128,8,0,24" Width="172" ItemContainerStyle="{DynamicResource ListBoxItemStyle1}" Name="listbox1" FontSize="16" />
	</Grid>
</Window>

把IsSelected触发器下面的改变背景色属性删掉
<Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/> 这个删掉就可以

如果发现选中的时候变成空白，可以把前景色设置成不是白色的颜色
