silverlight上委派出現的error message "偵測到配置循環。配置無法完成"

Question

如題，看起來是需要釋放甚麼的意思嗎 ?

程式碼如下

 AddHandler graphic_excepted.MouseLeftButtonDown, Sub(s As Object, e As GraphicMouseButtonEventArgs)

                                                             MyInfoWindow.Anchor = CType(e.Graphic.Geometry, MapPoint)

                                                             MyInfoWindow.Content = e.Graphic.Attributes

                                                             MyInfoWindow.ContentTemplate = CType(usercontrol.Resources("ExceptedLineTemplate"), DataTemplate)

                                                             MyInfoWindow.IsOpen = True

                                                         End Sub


        AddHandler graphic_actual.MouseLeftButtonDown, Sub(s As Object, e As GraphicMouseButtonEventArgs)

                                                           MyInfoWindow.Anchor = CType(e.Graphic.Geometry, MapPoint)

                                                           MyInfoWindow.Content = e.Graphic.Attributes

                                                           MyInfoWindow.ContentTemplate = CType(usercontrol.Resources("ActualLineTemplate"), DataTemplate)

                                                           MyInfoWindow.IsOpen = True

                                                       End Sub

Answer 1

我上次遇到這情況是事件處理時又觸發相同事件，所以事件一直處理不完。

Answer 2

graphic_actual和graphic_expected是什麼東東? 不要兩個都處理事件應該就可以了

Answer 3

回阿尼，的確是如此，感謝您。

Answer 4

回this，抱歉沒說明清楚，graphic_actual、graphic_expected是兩個graphic layer型態的圖層。

我是去做圖層的觸發動作。
