后面创建的DataTemplate代码 [英] create datatemplate code behind

问题描述

我试图创建的数据显示一个列表框视图，我希望它包含具有2列一个DataTemplate一个列表框产品ID和放大器;商品条码

I am trying to create a ListBox view for show data, and I want it to contain a ListBox with a datatemplate for 2 columns "Product ID & Product Barcode"

我想要么创建它使用纯C＃代码或者如果可能的话加载它通过XAML？如果我可以创建一个模板，我可以在C＃中的各种资源得到

I want to create it either using pure C# code or if possible load it through xaml? If I can create a template I can get in c# as a resource of sorts.

我已经取得直到现在：
在XAML：

What I have made until now is: In XAML :

<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>

在代码背后：

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;
        }

但似乎没有任何数据，任何建议请。
感谢，

but there is no data appears, any suggestion please. thanks,

推荐答案

您可以在XAML中定义的资源，并在后面的代码检索它，如果它有一个 X：。重点定义

You can define resources in xaml and retrieve it in code behind if it has an x:Key defined.

在您的XAML：

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

而在后面的代码：

And in your code behind :

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

或

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

这篇关于后面创建的DataTemplate代码的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
