Comobox 和 TextBox 在 ListView 中無法正確顯示 WPF C#

Question

目標是將 combobox 和文本框添加到列表視圖，以便用戶可以 select 從或進入每個控件。 它不顯示控件，而是顯示控件的屬性（對於 ComboBox，它是 items.Count，對於 TextBox，它是.Text）而不是實際控件。 我在網上查看了其他示例，但我不確定我做錯了什么。

XAML：

<Window x:Class="CompoundListView.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:CompoundListView"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800" Loaded="Window_Loaded">
    <Grid>
        <ListView x:Name="Lstv_UserControls" Margin="0,0,0,0">
            <ListView.View>
                <GridView AllowsColumnReorder="True">
                    
                    <GridViewColumn Header="Index" Width="Auto" DisplayMemberBinding="{Binding Path=ItemIndex}" />
                    <GridViewColumn Header="Type" Width="Auto"  DisplayMemberBinding="{Binding Path=cmb_Type}" />
                    <GridViewColumn Header="Name" Width="Auto" DisplayMemberBinding="{Binding Path=txt_Name}" />
                </GridView>
            </ListView.View>
        </ListView>

    </Grid>
</Window>

            TextBox txt = new TextBox();
            txt.Text = "Name";
            txt.HorizontalAlignment = HorizontalAlignment.Stretch;
            Lstv_UserControls.Items.Clear();// Clear the list view

                    cmb_Type = Cmb,
                    txt_Name = txt,
                };
                Lstv_UserControls.Items.Add(ListItem);
            }
        }
    }
}
public class ListViewUserControl
{
    public TextBox txt_Name { get; set; }
    public ComboBox cmb_Type { get; set; }
    public string ItemIndex { get; set; }
}

感謝評論，我想我明白了。 有幾件事是錯誤的：

• 將<DataTemplate>添加到每個列表視圖項。 一個用於 ComboBox，一個用於 TextBox
• 更正了 ComboBox ItemsSource="{Binding Path=cmb_Type.Items}"的綁定
• 更正了 TextBox Text="{Binding Path=txt_Name.Text}"的綁定

XAML：

<ListView x:Name="Lstv_UserControls" Margin="0,0,0,0">
    <ListView.View>
        <GridView AllowsColumnReorder="True">
            <GridViewColumn Header="Index" Width="Auto" DisplayMemberBinding="{Binding ItemIndex}" />

            <GridViewColumn x:Name="gridC_Type" Header="Type" Width="200">
                <GridViewColumn.CellTemplate >
                    <DataTemplate>
                        <ComboBox Margin="0,0,0,0" Width="{Binding Width, ElementName=gridC_Type,Converter={StaticResource PercentageConverter}}" ItemsSource="{Binding Path=cmb_Type.Items}" SelectedItem="{Binding Path=cmb_Type.SelectedItem}"  Height="Auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Foreground="Black"/>
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>

            <GridViewColumn x:Name="gridC_Name" Header="Name" Width="200">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <TextBox Text="{Binding Path=txt_Name.Text}" Width="{Binding Width, ElementName=gridC_Name,Converter={StaticResource PercentageConverter}}" Height="Auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/>
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>
