我想使科罗伯克用户群落到窗户内。
When the user click in any rectangle of the usercontrol, then I want to return this information to the Window. How can I do this please? Thanks!

科罗尔·皮克斯用户Control必须执行每次用户点击用户群中的一个试样时提出的一次活动。 如果你不了解如何开展某项活动,我只谈这一答案,我给你一个榜样。
例如: 您宣布,如果需要的话,会给您带来一些信息:
class RectangleClickedEventArgs : EventArgs
{
public int SomeValue { get; set; }
}
在您的用户控制下,您宣布:
public event EventHandler<RectangleClickedEventArgs> RectangleClicked;
在某些条件下,你以这种方式提出这项活动(即:
var temp = RectangleClicked;
if (temp != null)
{
var e = new RectangleClickedEventArgs{ SomeValue = 42};
temp(this, e);
}
阁下:
userControl.RectangleClicked += OnRectangleClicked;
如果是例行公事,你会采取预期行动:
private void OnRectangleClicked(object sender, RectangleClickedEventArgs e)
{
// Do what you want to do
}
希望......
