Get GridViewColumn Header value from ListView?

Question

I have this XAML code

<ListView Name="_lvContacts" ItemsSource="{Binding AccountPhonesList}"
                <ListView.View>
                    <GridView>
                        <GridViewColumn Header="{Binding Path=ColumnHeader1}" DisplayMemberBinding="{Binding Path=Home}" Width="70" />
                        <GridViewColumn Header="{Binding Path=ColumnHeader2}" DisplayMemberBinding="{Binding Path=Office}" Width="70" />
                        <GridViewColumn Header="{Binding Path=ColumnHeader3}" DisplayMemberBinding="{Binding Path=Mobile}" Width="70" />
                        <GridViewColumn Header="{Binding Path=ColumnHeader4}" DisplayMemberBinding="{Binding Path=Other}" Width="70" />
                        <GridViewColumn Header="{Binding Path=ColumnHeader5}" DisplayMemberBinding="{Binding Path=Email}" Width="70" />
                    </GridView>
                </ListView.View>
            </ListView>

And this is code behind

            for (int i = 0; i < _lvContacts.Items.Count; i++)
            {
                string header = _lvContacts.Items[i].ToString();
                MyFunction(header);
            }

How can I get the GridViewColumn Header from ListView?I was trying to get GridView from ItemSources but this is already used by collection!I dont know what else I can say about this.

I hope this is understandable.

Answer 1

In your case you can do:

((GridView)_lvContacts.View).Columns[i].Header

Answer 2

To get all of the headers, you can use the following code:

List<GridViewColumnHeader> headers = GetVisualChildren<GridViewColumnHeader>(_lvContacts).ToList();

public static IEnumerable<T> GetVisualChildren<T>(DependencyObject parent) where T : DependencyObject
    {
        int childrenCount = VisualTreeHelper.GetChildrenCount(parent);
        for (int i = 0; i < childrenCount; i++)
        {
            DependencyObject child = VisualTreeHelper.GetChild(parent, i);
            if (child is T)
                yield return (T)child;

            foreach (var descendant in GetVisualChildren<T>(child))
                yield return descendant;
        }
    }
