卡利微型取消从视图模型窗口关闭 [英] Caliburn Micro cancel window close from ViewModel

问题描述

当用户点击一个窗口的关闭按钮，是否有可能取消从视图模型收盘还是我不得不求助于后面的代码？

When the user clicks the close button of a Window, is it possible to cancel the close from the ViewModel or do I have to resort to code behind?

从我可以告诉你，CanClose或TryClose不会做的伎俩。

From what I can tell, CanClose or TryClose doesn't do the trick.

推荐答案

您可能已经尝试过这一点，但我已经刚刚创建了一个快速测试，从屏幕和压倒一切的CanClose得出一个视图模型。

You may have already tried this but I've just created a quick test, deriving a view model from Screen and overriding CanClose.

public class ShellViewModel : Screen
{
    public override void CanClose(Action<bool> callback)
    {
        //if(some logic...)
        callback(false); // will cancel close
    }
}
