</code>

and custom control like 

<code>

   

 public class MailAddressToken :RichTextBox        {            public static readonly DependencyProperty TokenTemplateProperty =                DependencyProperty.Register("TokenTemplate", typeof(DataTemplate), typeof(MailAddressToken));                public DataTemplate TokenTemplate            {                get { return (DataTemplate) GetValue(TokenTemplateProperty); }                set { SetValue(TokenTemplateProperty, value); }            }                public Func<string, object> TokenMatcher { get; set; }                             public MailAddressToken()            {                TextChanged += OnTokenTextChanged;            }                    private void OnTokenTextChanged(object sender, TextChangedEventArgs e)            {                var text = CaretPosition.GetTextInRun(LogicalDirection.Backward);                if (TokenMatcher != null)                {                    var token = TokenMatcher(text);                    if (token != null)                    {                        ReplaceTextWithToken(text, token);                    }                }            }                private void ReplaceTextWithToken(string inputText, object token)            {                // Remove the handler temporarily as we will be modifying tokens below, causing more TextChanged events                TextChanged -= OnTokenTextChanged;                    var para = CaretPosition.Paragraph;                    var matchedRun = para.Inlines.FirstOrDefault(inline =>                {                    var run = inline as Run;                    return (run != null && run.Text.EndsWith(inputText));                }) as Run;                if (matchedRun != null) // Found a Run that matched the inputText                {                    var tokenContainer = CreateTokenContainer(inputText, token);                    para.Inlines.InsertBefore(matchedRun, tokenContainer);                        // Remove only if the Text in the Run is the same as inputText, else split up                    if (matchedRun.Text == inputText)                    {                        para.Inlines.Remove(matchedRun);                    }                    else // Split up                    {                        var index = matchedRun.Text.IndexOf(inputText) + inputText.Length;                        var tailEnd = new Run(matchedRun.Text.Substring(index));                        para.Inlines.InsertAfter(matchedRun, tailEnd);                        para.Inlines.Remove(matchedRun);                    }                }                    TextChanged += OnTokenTextChanged;            }                private InlineUIContainer CreateTokenContainer(string inputText, object token)            {                // Note: we are not using the inputText here, but could be used in future                    var presenter = new ContentPresenter()                {                    Content = token,                    ContentTemplate = TokenTemplate,                };                    // BaselineAlignment is needed to align with Run                return new InlineUIContainer(presenter) { BaselineAlignment = BaselineAlignment.TextBottom };            }                    public object OnTokendelete { get; set; }        }

</code>


This will create token template of TextBlock

I want to retrieve all txtblock items in code Behind of usercontrol.
