Adding items in WPF ListView with columns

Question

I use this XAML code for the ListView:

 <ListView> <ListView.View> <GridView> <GridViewColumn DisplayMemberBinding="{Binding Path=Flag}" /> <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Path=Name}" /> <GridViewColumn Header="Ip Address" DisplayMemberBinding="{Binding Path=IpAddress}" /> </GridView> </ListView.View> </ListView>

And this is how I add items to the ListView:

ServerListItem item = new ServerListItem { Flag = "IL", Name = "Sample Server", IpAddress = "sample-server.com" }; lvServerList.Items.Add(item);

Here is the ServerListItem class:

public class ServerListItem { public string Flag; public string Name; public string IpAddress; }

The item is added to the ListView but all columns are empty. What should I do?

WPF does not bind to fields, only to properties. Flag, Name and IpAddress are defined as public fields on your class. Change the class definition to use auto properties instead:

public class ServerListItem { public string Flag { get; set; } public string Name { get; set; } public string IpAddress { get; set; } }
