mvvm - 如何将ActiveX控件关联到事件/更改到我的ViewModel中？

Question

我已经将WindowsMediaPlayer ActiveX添加到了WPF/MVVM应用程序中。现在，我需要控件对 View 模型中发生的更改使用react(最重要的是，当我的集合中的当前选择发生更改时更新URL)。基于Walkthrough: Hosting an ActiveX Control in WPF，我的Loaded事件中包含以下内容:

// Create the interop host control.
System.Windows.Forms.Integration.WindowsFormsHost host =
new System.Windows.Forms.Integration.WindowsFormsHost();

// Create the ActiveX control.
AxWMPLib.AxWindowsMediaPlayer axWmp = new AxWMPLib.AxWindowsMediaPlayer();

// Assign the ActiveX control as the host control's child.
host.Child = axWmp;

// Add the interop host control to the Grid
// control's collection of child controls.
this.pnlMediaPlayer.Children.Add(host);

问题是-如何在 View 模型中的属性更改时更新axWMP.URL控件属性？

Answer 1

好的，使用Windows.Forms.Binding:

axWmp.DataBindings.Add(new System.Windows.Forms.Binding("URL",(DisplayViewModel)this.DataContext,"Source"));
