WPF Error 40 BindingExpression path error: property not found on 'object'

Question

I\'m banging my head on my desk with this binding error.. I have checked several of the postings for the BindingExpression path error and cannot see anything t

Answer 1

This error may also occur when you were previously trying to bind inaccessible or non-existing Enumerable instance using XAML property <ItemsSource>

When you correct the ItemsSource with the correct value XAML doesn't automatically reilitialize the collection of items.

So when I was using the ListBox UI - list representation I faced this in the properties:

Deleting all the items in collection and correcting ItemSource value was the key.

Answer 2

After looking at Shahid's answer, I noticed in my case that I had set the DataContext to a reference in the Loaded event instead of in the constructor. Moving it to the constructor fixed the issue.

Answer 3

I had the same problem and in my case I was using bool instead of Boolean. As soon as I changed it, it's working as expected.

Answer 4

public Window()
{
      this.DataContext = this;
      InitializeComponent();
}
public string Name {get;}
//xaml
<TextBlock Text="{Binding Name}"/>

Properties Name should be public and { get; }

Answer 5

I got this error and my case was as simple as setting the String I was binding to from private to public.

Careless mistake writing my backing field.

Answer 6

I had same problem because class of object from which I was pulling out data didn't have get; and set; on its properties.

this didn't work:

public string Name;

but this worked:

public string Name{ get; set; }
