Custom WPF ListBox using c#

Question

First step : a simple ListBox

<ListBox Height="95" HorizontalAlignment="Left" Margin="17,0,0,0" Name="myList" VerticalAlignment="Top" Width="287">

with that code :

myList.Items.Add("toto");

Ok, it's working fine.

Second step : I want to have two columns for each row.

So I tried that

<ListBoxItem Name="my_item">
    <StackPanel Orientation="Horizontal">
        <TextBlock Name="my_item_id"></TextBlock>
        <TextBlock Name="my_item_name"></TextBlock>
    </StackPanel>
</ListBoxItem>

But in my code ?

I tried

my_item_id = "1234";
my_item_name = "toto";
myList.Items.Add(my_item);

But it's not working ... I suppose I'm doing wrong but then how to make it working ?

Thanks.

Answer 1

1. You should assign an ItemTemplate to the ListBox which binds to properties on the items. e.g.

   <ListBox.ItemTemplate>
       <DataTemplate>
           <StackPanel>
               <TextBlock Text="{Binding Id}"/>
               <!-- ... -->
   

2. You add items which have those properties, e.g. anonymous objects:

   myList.Items.Add(new { Id = "Lorem", ... });
