问题描述

我有这样的列表视图。

i have a list view like this .

<ListView x:Name="Source_List"
          ItemsSource="{Binding Lines}"
          IsSynchronizedWithCurrentItem="True"
          SelectionChanged="Source_List_SelectionChanged">
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="HorizontalContentAlignment"
                    Value="Stretch" />
        </Style>
    </ListView.ItemContainerStyle>
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Line"
                            Width="50"
                            DisplayMemberBinding="{Binding LineNumber}" />
            <GridViewColumn Header="Start Time"
                            Width="100"
                            DisplayMemberBinding="{Binding StartTime , Converter={StaticResource LineTimeToString}}" />
            <GridViewColumn Header="End Time"
                            Width="100"
                            DisplayMemberBinding="{Binding EndTime ,Converter={StaticResource LineTimeToString}}" />
            <GridViewColumn Header="Text"
                            Width="500">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <TextBox Text="{Binding Path=Context ,Mode=TwoWay}" />
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
            <GridViewColumn Header="Original Text"
                            DisplayMemberBinding="{Binding Context ,Mode=OneTime}" />
        </GridView>
    </ListView.View>
</ListView>

我要访问所选项目作为一个文本框里面的文本框中。（在code后面）
我怎样才能做到这一点？

I want to access the text box inside the selected items as a textbox.(in code behind ) how can i do this?

推荐答案

您可以查看在文本框UI元素（如果您的texblock点击）

you can acces to textbox ui element (if your texblock is clicked)

     TextBlock content = ((FrameworkElement)e.OriginalSource) as TextBlock;

否则，如果您texblock是一个网格内使用

else if your texblock is inside a grid use

      Grid c = ((FrameworkElement)e.OriginalSource) as Grid;

和搜索网格（C）的孩子。

and search for the grid(c) children.
