要求:评论宝贝的时候一个订单里面包含多个产品,获取对产品的评论内容哦
1. xaml界面
1 <ListView x:Name="lvDetail">
2 <ListView.ItemTemplate>
3 <DataTemplate>
4 <StackPanel>
5 <RelativePanel Padding="10,0,0,0">
6 <Image x:Name="imgoods" Height="75" Width="75" Source="{Binding GoodsPicture}" />
7 <TextBlock x:Name="tbName" Text="{Binding GoodsName}" FontSize="16" RelativePanel.RightOf="imgoods" Margin="10,0,0,0" />
8 <TextBlock x:Name="tbColor" Text="{Binding SpecValue}" Foreground="#C5C5C5" RelativePanel.Below="tbName" RelativePanel.RightOf="imgoods" Margin="8,5,0,0"/>
9 <TextBlock x:Name="tbUnitPrice" RelativePanel.AlignRightWithPanel="True" Margin="0,0,10,0">
10 <Run Text="¥" Foreground="Red"/>
11 <Run Text="{Binding UnitPrice}" FontSize="16" Foreground="Red"/>
12 </TextBlock>
13 <TextBlock RelativePanel.AlignRightWithPanel="True" RelativePanel.AlignVerticalCenterWithPanel="True" Margin="0,0,10,0">
14 <Run Text="x"/>
15 <Run Text="{Binding Quantity}" />
16 </TextBlock>
17 </RelativePanel>
18 <!-- 评价内容-->
19 <Grid Margin="10" BorderBrush="Gray" BorderThickness="1" CornerRadius="2">
20 <TextBox x:Name="tbContent" Text="{Binding Path=Content, Mode=TwoWay}" BorderBrush="Transparent" TextWrapping="Wrap" Height="100" PlaceholderText="亲,写点什么吧,您的意见对其他买家提供很多帮助"/>
21 </Grid>
22 </StackPanel>
23 </DataTemplate>
24 </ListView.ItemTemplate>
25 </ListView>
要求:获取ListView中x:Name为tbContent的值(评论内容)
第一步:绑定TextBox的值使用Mode=TwoWay
<TextBox x:Name="tbContent" Text="{Binding Path=Content, Mode=TwoWay}" BorderBrush="Transparent" TextWrapping="Wrap" Height="100" PlaceholderText="亲,写点什么吧,您的意见对其他买家提供很多帮助"/>
第二步:GoodsList集合的实体(也就是评论内容所在的实体模型)要实现INotifyPropertyChanged接口
1 public class Goods : INotifyPropertyChanged
2 {
3 private string content;
4 /// <summary>
5 /// 内容(评价宝贝使用)
6 /// </summary>
7 public string Content
8 {
9 get
10 {
11 return content;
12 }
13 set
14 {
15 content = value;
16 if (this.PropertyChanged != null)
17 {
18 this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs("Content"));
19 }
20 }
21 }
22 public event PropertyChangedEventHandler PropertyChanged;
23 }
第三步:绑定数据源
private
ObservableCollection
<
Goods
> GoodsList =
new
ObservableCollection
<
Goods
>();
//商品列表
lvDetail.ItemsSource = respOrder.OrderDetail.GoodsList;
GoodsList = respOrder.OrderDetail.GoodsList;
第四步:点击提交获取值
在界面写评论内容会自动在数据源绑定的
GoodsList中的Content属性中
