简单的WPF绑定无法正常工作

Question

I'm learning WPF, and I'm stuck with Data Bindings. I have a TreeView, which ItemSource is set to a ObserveableCollection<UIBrowserItem> .

My Binding looks like:

<TreeView>
    <TreeView.ItemContainerStyle>
        <Style TargetType="TreeViewItem">
            <Setter Property="Header" Value="{Binding Path=Title}"/>
        </Style>
    </TreeView.ItemContainerStyle>
</TreeView>

And my UIBrowserItem is very basic:

public class UIBrowserItem 
{
    public string Title = "Test";
}

But the Items in the TreeView won't have a header set ..

If you need further information, tell me

Answer 1

You can only bind to public properties , you have a public field. Your code should be:

public class UIBrowserItem 
{
    private String title = "Test";
    public string Title
    {
       get { return title; }
       set { title = value; }
}

If the title can change at run time, you also need to implement INotifyPropertyChanged .
