Listbox Databinding in wpf
提问by Ahmad Gulzar
I am binding the data coming form database to ListBoxItem's, below is the code:
我将来自数据库的数据绑定到ListBoxItem's，下面是代码：
public void load_users()
{
RST_DBDataContext conn = new RST_DBDataContext();
List<TblUser> users = (from s in conn.TblUsers
select s).ToList();
Login_Names.ItemsSource = users;
}
And in XAML, there is the below code:
在 XAML 中，有以下代码：
<ListBox Name="Login_Names"
ItemsSource="{Binding Path=UserName}"
HorizontalAlignment="Left"
Height="337" Margin="10,47,0,0"
Padding="0,0,0,0" VerticalAlignment="Top" Width="156">
But it does not works, it shows table name, but I need to see the usernames coming from table, there is column called UserName in TblUsers.
但它不起作用，它显示表名，但我需要查看来自表的用户名，TblUsers 中有名为 UserName 的列。
Thanks in Advance.
提前致谢。

try this
尝试这个
Create DataTemplate in resource section and then assign it to listbox
在资源部分创建数据模板，然后将其分配给列表框
<Grid.Resources>
<DataTemplate x:Key="userNameTemplate">
<TextBlock Text="{Binding Path=UserName}"/>
</DataTemplate>
<ListBox Name="listBox" ItemsSource="{Binding}"
ItemTemplate="{StaticResource userNameTemplate}"/>

Since the ItemsSource is set already in code behind, set the DisplayMemberPath to UserName in XAML.
由于 ItemsSource 已在后面的代码中设置，因此在 XAML 中将 DisplayMemberPath 设置为 UserName。
<ListBox Name="Login_Names"
DisplayMemberPath="UserName"
HorizontalAlignment="Left"
Height="337" Margin="10,47,0,0"
Padding="0,0,0,0" VerticalAlignment="Top" Width="156">
