C# WPF DataGrid bind XML

Question

This XML is deserialized properly from a website and returned as a class object. For example, I can call balanceResponse.accountId in my method and it will display a value, so I know it is working. I use the same process for other web requests and have not had an issue binding them to a WPF DataGrid.

What am I doing wrong in the XAML? It is not displaying any values.

The XML class was generated with special copy paste in Visual Studio by the way.

XAML:

       <DataGrid x:Name="accountBalanceGrid" SelectionMode="Single" IsReadOnly="True" 
              ItemsSource="{Binding BalanceResponse}" AutoGenerateColumns="True">

              <DataGrid.Columns>
                       <DataGridTextColumn Header="Account ID" Binding="{Binding accountId}" > 
                       </DataGridTextColumn>
              </DataGrid.Columns>

    </DataGrid>

Method:

     private async Task PopulateAccount()
    {
        BalanceResponse balanceResponse = new BalanceResponse();
        balanceResponse = await api.GetAccountBalance();
        accountBalanceGrid.DataContext = balanceResponse;
    }

What is your actual question? The ItemsSource is supposed to be set or bound to an IEnumerable. — mm8

You set the DataContext to a BalanceResponse which doesn't seem to have any BalanceResponse property that you are trying to bind to. Why would it display any values? — mm8

Where is your collection or enumerable of accounts to begin with? — mm8
– mm8, Commented Dec 2, 2020 at 15:11
Try this: accountBalanceGrid.ItemsSource = new BalanceResponse[1] { balanceResponse }; — mm8

The ItemsSource is supposed to be set or bound to an IEnumerable. You set the DataContext to a BalanceResponse object which doesn't seem to have any BalanceResponse property that you are trying to bind to:

ItemsSource="{Binding BalanceResponse}"

If there is no collection or enumerable of responses, you have to create one yourself:

accountBalanceGrid.ItemsSource = new BalanceResponse[1] { balanceResponse };
