我有下面的列表框,我从一个类(SavedDataClass)定义绑定数据。当用户点击链接“更新”时,我想访问该特定SavedDataClass实例的其他成员的整个数据。这是可能的像那样访问数据?我的意思是当调用其成员之一时,如何访问列表框项实例中的其他xxaml控件数据。
<ListBox x:Name="lstAreaDetails" Grid.Row="1" Margin="0,10,0,0" >
<ListBox.ItemTemplate >
<DataTemplate >
<StackPanel >
<StackPanel Orientation="Horizontal">
<TextBlock Foreground="White" Name="MyDateTime" Text="{Binding MyDateTime}"></TextBlock>
</StackPanel>
<StackPanel >
<HyperlinkButton Content="{Binding SavedName}" Name="lnkSAvedName" Click="HyperlinkButton_Click_1" />
<HyperlinkButton Content="{Binding Update}" Name="lnkUpdate" Click="lnkUpdate_click"/>
</StackPanel>
<TextBlock Text="{Binding ResAddress}" Name="txtResAddress" TextWrapping="Wrap" ></TextBlock>
<TextBlock >OtherDetails:</TextBlock>
<TextBlock Text="{Binding Area}" Name="txtArea" TextWrapping="Wrap"></TextBlock>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
public class SavedDataClass
{
public string MyDateTime { get; set; }
public string SavedName { get; set; }
public string Update{ get; set; }
public string ResAddress { get; set; }
public string Area{ get; set; }
public string OptionalAddressLine1{ get; set; }
public string OptionalAddressLine2{ get; set; }
}
更新链接点击将具有以下事件处理程序:
private void lnkUpdate_click(object sender, RoutedEventArgs e)
{
//here I want to access other controls data e.g. MyDateTime,SavedName,ResAddress,Area,OptionalAddressLine1,OptionalAddresLine2
}

在这些情况下,Tag
的{{1}}属性用于传输驻留在您绑定的FrameworkElement
内的基础数据对象。您的代码看起来有点像这样:
DataContext
请注意,在第二个超链接按钮上,我添加了<ListBox x:Name="lstAreaDetails" Grid.Row="1" Margin="0,10,0,0">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Foreground="White" Name="MyDateTime" Text="{Binding MyDateTime}"></TextBlock>
</StackPanel>
<StackPanel >
<HyperlinkButton Content="{Binding SavedName}" Name="lnkSAvedName" Click="HyperlinkButton_Click_1" />
<HyperlinkButton Tag="{Binding}" Content="{Binding Update}" Name="lnkUpdate" Click="lnkUpdate_click"/>
</StackPanel>
<TextBlock Text="{Binding ResAddress}" Name="txtResAddress" TextWrapping="Wrap" ></TextBlock>
<TextBlock >OtherDetails:</TextBlock>
<TextBlock Text="{Binding Area}" Name="txtArea" TextWrapping="Wrap"></TextBlock>
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
属性。你的代码隐藏看起来有点像这样:

希望这有帮助。
