Silverlight Bing地图中的可拖动和可单击图钉 [英] Draggable AND clickable pushpin in silverlight bing map

问题描述

我正在尝试在Silverlight Bing地图中创建一个可拖动和可点击的图钉。我在这里 http：//中找到了一些代码： //pietschsoft.com/post/2010/05/30/Draggable-Pushpins-using-Bing-Maps-Silverlight-Control.aspx 来实现可拖动部分。

I'm trying to create a pushpin in a Silverlight Bing Map that is both draggable as well as clickable. I found some code here http://pietschsoft.com/post/2010/05/30/Draggable-Pushpins-using-Bing-Maps-Silverlight-Control.aspx to achieve the draggable part.

我已经将mouseclick映射到地图上以放置大头针。

I've mapped mouseclick on the map to drop a pin.

但是，问题（而且默认图钉也存在）是在图钉上似乎首先由地图控件处理，所以我最终放弃了另一个图钉，而不是在图钉上注册事件。

However, the problem (and this exists with the default pushpin as well) is that clicking on the pushpin seems to be handled by the map control first so I end up dropping another pin, instead of registering an event on the pushpin.

如果我将图钉替换为作为按钮的ControlTemplate，我可以捕获单击，但是现在我没有可拖动的图钉。

If I replace the pin with a ControlTemplate that is a button, I can trap the click, but now I don't have a draggable pushpin.

有人可以推荐解决方案吗？

Can anyone recommend a solution ?

推荐答案

我发现这种方法有效。

I've found this approach to work. Recording it here so that it helps someone else.

1. 从上方链接为DraggablePushpin创建内容模板，使其仅包含一个DraggableButton（下面）。



2. 从Button继承以创建DraggableButton（在上面的模板中引用）

1. Create a Content Template for the DraggablePushpin from above link so that it only contains a DraggableButton(below).

2. inherit from Button to create a DraggableButton (referenced in the template above)

在此DraggableButton中，覆盖OnMouseLeftButtonDown和OnMouseLeftButtonUp并将它们传递给DraggablePushpin。我在DraggableButton上创建了一个名为ThePin的属性，并在DraggablePushpin的OnApplyTemplate方法中进行设置。您可以在OnApplyTemplate中调用GetTemplateChild（）以获得对图钉中DraggableButton实例的引用。

In this DraggableButton, override the OnMouseLeftButtonDown and the OnMouseLeftButtonUp and pass them to the DraggablePushpin. I created a property called ThePin on the DraggableButton and set that in the OnApplyTemplate method of the DraggablePushpin. You can call GetTemplateChild() in OnApplyTemplate to get a reference to the DraggableButton instance in the pushpin.

DraggableButton现在可以覆盖Click事件以进行自定义操作，还将其他事件传递给DraggablePushpin，以使其按预期工作。

The DraggableButton can now override the Click event for custom actions and also pass through the other events to the DraggablePushpin so that it works as expected.

也许有一种更清洁的方法这，但这对我有用。

There maybe a cleaner way to do this, but this is what worked for me.
