Question

I have a listbox with a data template bound to a list<class> in the program.

<DataTemplate x:Key="pTemplate">
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="{Binding Ref}" Padding="5,0,0,0"/>
                <StackPanel Name="taggedA" Tag="{Binding A}" Orientation="Horizontal">
                    <TextBlock Name="selectedA" Text="{B}" />
                </StackPanel>
                <Image Name="ind" Width="40" Height="40" />
            </StackPanel>
</DataTemplate>

On button click, I want to go over all the elments of the listbox and check if the stackPanel taggedA‘s tag == textblock selectedA‘s text.

This is to be done for each of the items in the list box and the data template is as above. How can this be done?

Easier to compare the binding source directly:

ListBox l = myListBox;
for (int i = 0; i < l.Items.Count; i++)
{
    var boundObject = (MyClass)l.Items[i];
    MessageBox.Show("They are equal? " + (boundObject.A == boundObject.B));
}
