UpdateSourceTrigger为显式MVVM

问题描述

大家好，



我有一个修改实体的视图模型，我想在用户按下保存按钮时更新源，所以我设置了UpdateSourceTrigger显式，但现在我如何更新MVVM模式中的源？



使用显式绑定，一直期望使用BindingExpression更新绑定源。



我也试过带参数的继电器命令。但这一切都是基于假设。



告诉我。在此先感谢

解决方案

Hi all,

I have a view model to modify an entity and i want update the source when the user press save button so I’ve set the UpdateSourceTrigger to explicit but now how can i update the source in MVVM pattern?

With explicit binding, this has always been expected to update the binding source using BindingExpression.

I have tried relay command with parameters also. But it all goes by assumption.

Advise me. Thanks in advance
