Showing a SelectedItem's Property

So I enabled a rightclick option for my DataGrid. I want to display just one property of the selecteditem but it's not behaving like how I would like. It displays my namespace and extra.

public class Paymentinfo
{
   public int PaymentNo { get; set; }
   public String Date { get; set; }
   public double Payment { get; set; }
   public double Principle { get; set; }
   public double Interest { get; set; }
   public double Balance { get; set; }
}

private void MenuItem_OnClick(object sender, RoutedEventArgs e)
{
    MessageBox.Show(AmortGrid.SelectedItem.ToString());
}

I am trying to implement this without using a viewmodel! If I put a breakpoint where Messagebox is and put the cursor over the selectedItem then it'll display the properties paymentNo-date-payment-principle-interest-balance. The only value I require is PaymentNo

was hoping it'd be something like this 

MessageBox.Show(AmortGrid.SelectedItem.PaymentNo.ToString());

Create a ToString() method on PaymentInfo.

public class Paymentinfo
{
   public override string ToString()
   {
       return PaymentNo.ToString();
   }
}

You can also set the SelectedValuePath and instead of using SelectedItem use SelectedValue.

When you call ToString() like that, you get the name of the class type, which is what you're seeing.

If that's a collection of Paymentinfo, cast SelectedItem back to that type first:

MessageBox.Show(((Paymentinfo)AmortGrid.SelectedItem).PaymentNo.ToString());

FWIW, I'd reconsider the ViewModel. Far easier to test your code if you get it out of the code-behind.

You'd be able to bind your SelectedItem directly to a property in the ViewModel (perhaps called SelectedPaymentinfo), and then there'd be no messing around with casting.
