Question

In Windows 8, C# + xaml
i have some class

Class ABC
{
 public string a {get; set;}
 public void someMethod()
 {
  **some code, changing a**
 }
}

and binding in xaml

<ListBox x:Name="playlistBox">
     <ListBox.ItemTemplate>
          <DataTemplate>
               <StackPanel Orientation="Horizontal">
                     <TextBlock Text="{Binding a}"/>
                     <Button Name="removeAlbumBtn" Content="method" Click="**NEED BINDING TO SOMEMETHOD HERE**"/>
                </StackPanel>
           </DataTemplate>
      </ListBox.ItemTemplate>
  </ListBox>

So what i must type to call someMethod???

Answer 1

You need to handle the Click event through a handler method in the code behind of that xaml file. For example, if the xaml you show is in a MyControl.xaml. You’ll have a method like the following in the MyControl.xaml.cs:

private void removeAlbumBtn_Click(object sender, RoutedEventArgs e)
{
    var a = ((Button)sender).DataContext as ABC;

    if(a != null)
        a.someMethod();
}

And change the xaml to be:

<Button Name="removeAlbumBtn" Content="method" Click="removeAlbumBtn_Click"/>
