从DP回调WPF更新WindowsFormsHost控件

Question

我在WindowsFormsHost中的DataGridView周围有一个usercontrol包装器。

包装器有一个带回调的DP，但回调是静态的，所以它不能简单地在具有x：Name的windowsforms托管控件上执行代码。

如何在DP更新时更新WindowsFormsHost DataGridView？

我想做类似的事情，但我不能在DP回调中引用_gridView

 public LiteTable GridViewData
    {
        get { return (LiteTable)GetValue(GridViewDataProperty); }
        set { SetValue(GridViewDataProperty, value); }
    }

    private static void OnGridViewDataChanged(DependencyObject source, DependencyPropertyChangedEventArgs e)
    {
        _gridView.GetData((LiteTable)e.NewValue);
    }

    // Using a DependencyProperty as the backing store for GridViewData.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty GridViewDataProperty =
        DependencyProperty.Register("GridViewData", typeof(LiteTable), typeof(LiteGridViewWrapper), new UIPropertyMetadata(null, OnGridViewDataChanged));

WPF传递其属性在source参数中更改的实例 您可以将此参数强制转换为类型并获取字段。

var me = (MyControl)source;
me._gridView.GetData((LiteTable)e.NewValue);
