C# WPF Listview 如何设置某一行的颜色

Posted 2023-03-16

比如listview里边包含了姓名,年龄两项,如何将年龄大于90岁的行的所有文字变红

你得自己写个转换器，在绑定模板中将某个属性转换从而返回背景色，即可

                    </GridViewColumn>

                </GridView>

            </ListView.View>

        </ListView>

参考技术A 你在添加listview的时候 ，根据年龄的值来设置每一项的ListViewItem的背景色就可以了，
