How to Identify button for list item - wpf

Question

How do i access the object UserNames, that is bound to the list??
What i did so far:
Item of the list is object in my case:
new List<UserNames>();
this.users.Add(new UserNames() {Id = 1, UserName = "name 1"});
I am using data template for which i have label and button.
My List is as follows:
<ListBox Grid.Column="1" Grid.Row="1" Name="listBox1" ItemsSource="{Binding}" SelectedValuePath="Id">
<ListBox.ItemTemplate>
<DataTemplate>
<WrapPanel Orientation="Vertical">
<StackPanel>
<Label Content="{Binding UserName}" />
</StackPanel>
<StackPanel Name="ButtonStackPanel">
<Button Name="MyButton" Content="Click Me" Click="MyButton_Click">
</Button>
</StackPanel>
</WrapPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Where my method for Button is. As you can see i did try to utilise the parent option, but without sucess
private void MyButton_Click(object sender, RoutedEventArgs e)
{
//StackPanel panel = (StackPanel)((Button)sender).Parent;
//WrapPanel wrapPanel = (WrapPanel) panel.Parent;
//ListItem listItem = (ListItem) wrapPanel.Parent;
//ListBox box = (ListBox) listItem.Parent;
//UserNames itemToReport = (UserNames) (box.SelectedItem);
//MessageBox.Show(itemToReport.UserName);
}

Answer 1

You can use the Button's DataContext, since it will be your UserName object
private void MyButton_Click(object sender, RoutedEventArgs e)
{
Button b = sender as Button;
UserNames data = b.DataContext as UserNames;
MessageBox.Show(data.UserName);
}
I've always thought that with WPF, your application is the DataContext, while the UI objects like Buttons, ListBoxes, TextBoxes, etc are simply a pretty layer that sits on top of the DataContext to allow the User to interact with it.

In the XAML, set the Tag property to the current item.
In the click handler, cast it back.
Usernames user = (sender as Button).Tag as Usernames;

Answer 3

To bind a datacollection it is often easiest to use an ObservableCollection (if the data is changing runtime). When you do the binding you have to define a datacontext, a datasoure and a datapath. I will advice you to read some more about binding on MSDN :D

Answer 4

This will work for you -
MessageBox.Show(((sender as Button).DataContext as UserNames).UserName);
