Question

I have got a listbox and I have to populate that with the elements from the query. The query is,

var query = from b in context.table select b; 
 List<Tab> reclist = q.ToList();

using LINQ how can I print all the obtained values in the listbox?

You’ll need to create a DataTemplate containing a TextBlock whose Text property you bind to a property on your object. So, some XAML something like;

<ListBox x:Name="MyListBox">
  <ListBox.ItemTemplate>
    <DataTemplate>
      <TextBlock Text="{Binding Name}" />
    </DataTemplate>
  </ListBox.ItemTemplate>
</ListBox>

Presuming your Tab class has a property called Name. Obviously if it doesn’t you’ll want to change the {Binding Name} portion of the XAML to match the property name that you want to display in the ListBox.

You then bind to your item;

MyListBox.ItemsSource = reclist;
