You can create a much more simple solution using ItemsControl. Second, You are trying to implement a Master-Detail pattern. The Combo-Box selected value is the Master and the TextBlock is the Details. I've wrote a simple example that do exactly what you want to do in my article:How to: Use the Master-Detail Pattern with WPF Hierarchical DataTemplate[^]Please review it. If you have more questions I'll be happy to help.Best Regards,Shai 这篇关于如何将组合框中的选定项绑定到datagrid中的textblock的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
