在后面创建数据模板代码

我正在尝试创建一个用于显示数据的列表框视图，并且希望它包含一个带有 2 列“产品 ID 和产品条形码”数据模板的列表框

我想使用纯 C# 代码创建它，或者如果可能的话通过 xaml 加载它？如果我可以创建一个模板，我就可以将 C# 作为某种资源。

到目前为止我所做的是： 在 XAML 中：

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="37*" />
        <RowDefinition Height="88*" />
    </Grid.RowDefinitions>
    <TextBlock Text="Type Your Search :" HorizontalAlignment="Left"  VerticalAlignment="Bottom" Width="112" Height="15.96" Margin="20,0,0,4" />

    <TextBox HorizontalAlignment="Right" VerticalAlignment="Bottom" Height="25" Width="300" Margin="0,0,44,0" x:Name="txtCAuto" TextWrapping="NoWrap" HorizontalContentAlignment="Right" />

    <ListBox x:Name="lbSuggestion" SelectionChanged="lbSuggestion_SelectionChanged" Foreground="Black" Width="300" Margin="0,0,44,0"  FlowDirection="RightToLeft" Background="LightYellow" Grid.Row="1" Visibility="Collapsed"  ScrollViewer.HorizontalScrollBarVisibility="Auto" ItemsSource="{Binding}"  HorizontalAlignment="Right" VerticalAlignment="Top" HorizontalContentAlignment="Right" BorderBrush="Transparent"  Grid.IsSharedSizeScope="True">
    </ListBox>
</Grid>

在隐藏代码中：

string typedString = txtCAuto.Text.ToUpper();
        List<string> autoList = new List<string>();
        autoList.Clear();

         prodDetails ps = SelProd4Sale();

        foreach (string item in ps.ProdBrcdList)
        {
            if (!string.IsNullOrEmpty(txtCAuto.Text))
            {
                if (item.StartsWith(typedString))
                {
                    //autoList.Add(item);
                    FrameworkElementFactory colProdID = new FrameworkElementFactory(typeof(TextBlock));
                    Binding prodID = new Binding(ps.ProdIDList.ToString());
                    colProdID.SetBinding(TextBlock.TextProperty, prodID);

                    FrameworkElementFactory colProdBarcode = new FrameworkElementFactory(typeof(TextBlock));
                    Binding prodBarcode = new Binding();
                    prodBarcode.Path = new PropertyPath(ps.ProdBrcdList.ToString());
                    colProdBarcode.SetBinding(TextBlock.TextProperty, prodBarcode);


                    FrameworkElementFactory sb = new FrameworkElementFactory(typeof(StackPanel));
                    sb.AppendChild(colProdID);
                    sb.AppendChild(colProdBarcode);

                    dTemplate = new DataTemplate { VisualTree = sb };
                    dTemplate.Seal();


                }
            }
        }

        if (autoList.Count > 0)
        {
            lbSuggestion.ItemTemplate = dTemplate;
            //lbSuggestion.ItemsSource = autoList;
            lbSuggestion.Visibility = Visibility.Visible;
        }
        else if (txtCAuto.Text.Equals(""))
        {
            lbSuggestion.Visibility = Visibility.Collapsed;
            lbSuggestion.ItemsSource = null;
        }
        else
        {
            lbSuggestion.Visibility = Visibility.Collapsed;
            lbSuggestion.ItemsSource = null;
        }

但没有出现任何数据，请任何建议。 谢谢，

您可以在 xaml 中定义资源，并在后面的代码中检索它（如果它有）x:Key定义的。

在你的 xaml 中：

<DataTemplate x:Key="anyId">...</DataTemplate>

在你的代码后面：

var dataTemplate = Application.Current.TryFindResource("anyId") as DataTemplate;

or

var dataTemplate = Application.Current.FindResource("anyId") as DataTemplate;
