Question

现在，我刚刚得到AG_E_PARSER_BAD_PROPERTY_VALUE。我认为这是因为我没有对我的绑定属性做任何事情。我有什么可以做的吗？

                    <ListBox.ItemTemplate>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal">
                                <Image Name="imgSvrIco" Source="{Binding pic}"/>
                                <StackPanel Orientation="Vertical" Margin="2,2,2,10" Tag="{Binding tag}" MouseLeftButtonUp="StackPanel_MouseLeftButtonUp_1">
                                    <TextBlock Name="lbTitle"  Text="{Binding title}" Margin="0,0,0,0" FontWeight="Bold" />
                                    <TextBlock Text="{Binding text}" Visibility="{Binding textVisibility}"/>
                                    <StackPanel Orientation="Horizontal">
                                        <TextBlock Text="{Binding time}"/>
                                        <TextBlock Text=" By " />
                                        <!--<my:UserBrand Address="{Binding address}" />-->
                                    </StackPanel>
                                </StackPanel>
                            </StackPanel>
                        </DataTemplate>
                    </ListBox.ItemTemplate>

信息不足。

AG_E_PARSER_BAD_PROPERTY_VALUE异常包含问题发生的确切指针（即Xaml文件中的行/位置）。找到它，识别Xaml代码中的位置并尝试修复它。

其次，即使你向我们展示了Xaml的位置，我们也只能在你隐藏语义时检查语法错误 - 对应。 C＃代码。

你说“我确定绑定表达式是正确的”，但通常容易被忽视，例如“地址”而不是“地址”。（你真的使用非标准命名约定吗？）

如何将值绑定到用户控件属性？
