It is primarily used to navigate within the same browser tab.  To open a URL in a new tab or window, you can use JavaScript interop in Blazor.

How do I make the items in the ListBox be a combination of values from 2 different columns in my data source?

First create a custom DataTemplate that uses adjacent TextBlocks to render values from 2 different columns next to each other. <Window.Resources> <DataTemplate x:Key=’lbItemsTemplate’> <StackPanel FlowDirection=’LeftToRight’ Orientation=’Horizontal’> <TextBlock Text='{Binding Path=Title}’></TextBlock> <TextBlock Text=’ \ ‘></TextBlock> <TextBlock Text='{Binding Path=Summary}’></TextBlock> </StackPanel> </DataTemplate> </Window.Resources> Above, Title and Summary are the two columns. Then specify this template in your ListBox: <ListBox x:Name=’ListView1′ ItemTemplate='{StaticResource lbItemsTemplate}’ ItemsSource='{StaticResource InventoryData}’> </ListBox>
