Question

我正在尝试创建建议列表。这意味着当我键入条形码时，所有以我键入的内容开头的条形码都应显示在另一个数据网格中。数据网格显示的行数正确，但即使标题未显示，内容也不正确。

我尝试创建具有6列的Datagrid，并编写了代码以在条形码文本框的TextChanged属性中显示Datagrid。

我的XAML部分：

 <Grid Grid.Column="0" Grid.Row="1" Margin="10">
                    <DataGrid CanUserAddRows="False"  Visibility="Hidden" Style="{StaticResource DataGridListing}" x:Name="DataGridSalesSuggestion" Height="{Binding ActualHeight, RelativeSource={RelativeSource AncestorLevel=1, AncestorType={x:Type Grid}, Mode=FindAncestor}}" Width="{Binding ActualWidth, RelativeSource={RelativeSource AncestorLevel=1, AncestorType={x:Type Grid}, Mode=FindAncestor}}">

                        <DataGridTextColumn IsReadOnly="True" Width="1*" Header="{Binding barcode, Source={StaticResource Strings}}" x:Name="DataGridSuggestionItemName"  Binding="{Binding BarCode}"  />
                        <DataGridTextColumn IsReadOnly="True" Width="1*" Header="{Binding ItemCode, Source={StaticResource Strings}}" x:Name="DataGridSuggestionItemCode"  Binding="{Binding ItemCode}"  />
                        <DataGridTextColumn IsReadOnly="True" Width="1*" Header="{Binding itemName, Source={StaticResource Strings}}" x:Name="DataGridSuggestionBarcode"   Binding="{Binding ItemName}" />
                        <DataGridTextColumn IsReadOnly="True" Width="1*" Header="{Binding UnitQuantity, Source={StaticResource Strings}}" x:Name="DataGridSuggestionUnitQty"  Binding="{Binding UnitQuantity}"  />
                        <DataGridTextColumn IsReadOnly="True" Width="1*" Header="{Binding price, Source={StaticResource Strings}}" x:Name="DataGridColumnSuggestionPrice"  Binding="{Binding PricePerUnit}" />
                        <DataGridTextColumn IsReadOnly="True" Width="1*" Header="{Binding StockQty, Source={StaticResource Strings}}" x:Name="DataGridColumnSuggestionStockQty"  Binding="{Binding StockQuantity}" />

                    </DataGrid>
                </Grid>

隐藏代码：

private void TextboxBarCodeTextchanged(object sender, TextChangedEventArgs e)
    {
        Stock obj = DataGridSalesDetails.SelectedItem as Stock;


        DataGridSalesSuggestion.Items.Clear();
        for (int i = 0; i < AllStockList.Count; i++)
        {
            if (!string.IsNullOrEmpty(obj.BarCode))
            {
                if (AllStockList[i].BarCode.StartsWith(obj.BarCode, StringComparison.InvariantCultureIgnoreCase))
                {

                    Stock vend = AllStockList[i] as Stock;
                    DataGridSalesSuggestion.Items.Add(vend);
                    DataGridSalesSuggestion.Visibility = Visibility.Visible;
                }
            }
        }
        if (DataGridSalesSuggestion.Items.Count > 0)
        {
            DataGridSalesSuggestion.Visibility = Visibility.Visible;

        }
        if (string.IsNullOrEmpty(obj.BarCode))
        {
            DataGridSalesSuggestion.Visibility = Visibility.Collapsed;
        }
    }

预期结果是此Datagrid应该显示与我在条形码文本框中键入内容相关的内容。

实际结果是此代码获取显示一个空的Datagrid。即使标题不显示。有人可以帮忙吗？ .net是新手

Datagrid显示为空的datagrid。连标题都没有显示
