Question

我正在寻找一些我正在写的WPF窗口的帮助。我想从一个非常混乱的ListView中获取特定列的值。这是XAML：

<Grid>
    <ListView Name="listViewItem" ClipToBounds="True" VerticalContentAlignment="Stretch" HorizontalContentAlignment="Stretch" SizeChanged="ListView_SizeChanged" Loaded="ListView_Loaded" TextOptions.TextHintingMode="Animated" Margin="0,0,83,0">
        <ListView.View>
            <GridView AllowsColumnReorder="False">
                <GridViewColumn Header="Company Name" Width="150">
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding CompanyName}" TextWrapping="Wrap" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
                <GridViewColumn Header="Company Address" Width="350">
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding CompanyAddress}" TextWrapping="Wrap" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
            </GridView>
        </ListView.View>
    </ListView>
</Grid>

listViewitem.SelectedItem或SelectedItems有任何会让我访问这些值的成员。访问子项也是不可能的，它们甚至都没有出现。

这就是我绑定的方式。

private void ListView_Loaded(object sender, RoutedEventArgs e)
{
    string connectionString = ConfigurationManager.ConnectionStrings["DB"].ConnectionString;
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        SqlCommand command = new SqlCommand("SELECT CompanyName, CompanyAddress FROM Groups", connection);
        SqlDataAdapter adapter = new SqlDataAdapter(command);
        DataTable dt = new DataTable("Groups");
        adapter.Fill(dt);
        listViewItem.ItemsSource = dt.DefaultView;
    }
}

Answer 1

您可以将SelectedItem转换为定义CompanyName和CompanyAddress属性的类型：

var selectedItem = listViewItem.SelectedItem as DataRowView;
if(selectedItem != null)
{
    string name = selectedItem["CompanyName"].ToString();
    ...
}

从填充了GridViews的ListView获取特定列的值
