【问题描述】:
我正在将 Silverlight 3 项目转换为 Silverlight 4。我最近让该项目能够运行,但在实例化搜索窗口时遇到了问题。 VS 向我抛出了以下错误:
Microsoft JScript runtime error: Unhandled Error in Silverlight Application Set property 'System.Windows.FrameworkElement.Style' threw an exception. [Line: 242 Position: 46] at System.Windows.Application.LoadComponent(Object component, Uri resourceLocator)
at ESM.Visualization.SearchWindow.InitializeComponent()

我研究了错误并尝试按照this solution重新安装 Silverlight。但是错误仍然发生。我查看了this SO question,但我的 App.xaml 几乎没有 242 行。这是我在第 242 行附近的 MainPage.xaml:
<StackPanel Orientation="Vertical" HorizontalAlignment="Left" Grid.Row="2" VerticalAlignment="Bottom">
<esriToolkit:Navigation x:Name="MapNavigation" Margin="5" Map="{Binding ElementName=MapWindow}" Visibility="Collapsed" />
<!--<esri:ScaleBar x:Name="MainScaleBar" Margin="5" MapUnit="DecimalDegrees" Foreground="Black"
Map="{Binding ElementName=MapWindow}"
DisplayUnit="Miles" Visibility="Visible" />-->
</StackPanel>
这是我尝试实例化的搜索窗口的 .xaml(在第 242 行左右):
<grid:AgDataGrid x:Name="grdAddressResults" Grid.Row="1" Grid.Column="0" ColumnsAutoWidth="True"
ShowTotals="False" FocusMode="Row" FocusedRowChanged="grdResults_FocusedRowChanged"
IsMultiSelect="False" Margin="0,10,0,0">
<grid:AgDataGrid.Columns>
<grid:AgDataGridColumn FieldName="Address" />
<grid:AgDataGridColumn FieldName="X" Visible="False" />
<grid:AgDataGridColumn FieldName="Y" Visible="False" />
</grid:AgDataGrid.Columns>
<grid:AgDataGrid.TotalSummary>
<grid:AgDataGridSummaryItem FieldName="Address" SummaryType="Count" Title="Matches Found" />
</grid:AgDataGrid.TotalSummary>
</grid:AgDataGrid>
【问题讨论】:
-
能否请您围绕异常消息提到的行显示 XAML 代码:[Line: 242 Position: 46]
-
我已经提供了 XAML 代码。
-
哪一行是242?
-
</StackPanel>是 MainPage.xaml 的第 242 行,</grid:AgDataGrid ...>是 SearchWindow.xaml 的第 242 行。
