我已经创建了一个带有DeepEarth地图控件的silverlight应用程序。这是我的基础XAML
<Grid x:Name="LayoutRoot" >
<!-- Map Control -->
<DeepEarth:Map x:Name="map" Margin="0,0,0,0">
<Controls:CoordControl VerticalAlignment="Bottom" HorizontalAlignment="Right" />
<Controls:ScaleControl VerticalAlignment="Bottom" HorizontalAlignment="Right" Margin="12,12,12,40" />
</DeepEarth:Map>
<Controls:NavControl x:Name="navControl" >
<StackPanel Orientation="Horizontal">
<Button x:Name="MyButton" Content="Hi" Click="MyButton_Click"></Button>
</StackPanel>
</Controls:NavControl>
</Grid>
我有一个我创建的行为类,我想附加到按钮
public Page()
{
InitializeComponent();
new ButtonActionWithCancel(MyButton, new CreatePointCommand(map));
}
void MyButton_Click(object sender, RoutedEventArgs e)
{
if (MyButton == null) throw new Exception("Wat?");
}
这是为了向MyButton做一些事情,挂钩一些事件和东西。问题是MyButton在运行时为空。怎么会?层次结构中的其他控件不为null。怎么回事?

当我离开测试版时,它停止了发生。
