Binding a string doesn't show up, Binding another type does… WPF
I just started with WPF and databinding. First question on databinding.
Databinding on {Binding Periode.Einde} where Einde is of type DateTime works,
{Binding Arrangement} where Arrangement is of type Enum works, {Binding Limo.Info} where Info is of type String doesn't work.
Somebody has an explanation for that?

Can you elaborate with more information? What is the DataContext Class for the item template? Is Limo is property? Is Limo.Info is property?

Sure, string is empty or null.

You should be binding itemssource of your listview to an observablecollection<t>. T should have a public limo property which should have a public info property which has a value set. I guess one of those things isn't true.

In your binding expression Text="{Binding Limo.Info}" then if Limo.Info is of type string, then there are only 3 possible scenarios as to why nothing appears in your UI
1) Limo object is null
2) Info string is null or empty
3) Limo.Info is spelled incorrectly, and it's actually something else.
It has to be one of those 3 scenarios. check the objects you are passing into your ListView
