从 DP 回调 WPF 更新 WindowsFormsHost 控件
我在 WindowsFormsHost 中的 DataGridView 周围有一个用户控件包装器。
包装器有一个带有回调的 DP，但回调是静态的，因此它不能简单地在具有 x:Name 的 windowsforms 托管控件上执行代码。
当 DP 更新时，如何更新 WindowsFormsHost DataGridView？
我想做这样的事情，但我无法在 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));
I have a usercontrol wrapper around a DataGridView in a WindowsFormsHost.
The wrapper has a DP with a callback, but the callback is static so it cannot simply execute code on the windowsforms hosted control that has an x:Name.
How can I update the WindowsFormsHost DataGridView when the DP gets updated?
I want to do something like this, but I cannot reference _gridView in the DP callback
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 传递在
source参数中属性发生更改的实例。您可以将此参数转换为您的类型并获取该字段。
WPF passes the instance whose property changed in the
sourceparameter.You can cast this parameter to your type and get the field.
