Hi Matthew Kraft

SORRY, 

yes, this is the RichTextBox .NET provided control in WPF?

i need in c# not in xaml

thank you very much

Hello Maria,

I'm trying to get is the same effect that I have here:
<RichTextBox Visibility = "Visible" x: Name = "TextLinkUrl" IsReadOnly = "True" IsDocumentEnabled = local "True": RTBNavigationService.Content = "{Binding Text, ElementName = TextWithUrl}" PreviewMouseLeftButtonDown = "TextLinkUrl_MouseLeftButtonDown">

but by code, the RTBNavigationService, works correctamense me, just do not know how to apply this binding by code correctly

the RTBNavigationService code is as follows:

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media.Imaging;

namespace RichTextBox_Hyperlink
{
public static class RTBNavigationService
{
private static readonly Regex regexUrl = new Regex(@"(?#Protocol)(?:(?:ht|f)tp(?:s?)\:\/\/|~/|/)?(?#Username:Password)(?:\w+:\w+@)?(?#Subdomains)(?:(?:[-\w]+\.)+(?#TopLevel Domains)(?:com|org|net|gov|mil|biz|info|mobi|name|aero|jobs|museum|travel|[a-z]{2}))(?#Port)(?::[\d]{1,5})?(?#Directories)(?:(?:(?:/(?:[-\w~!$+|.,=]|%[a-f\d]{2})+)+|/)+|\?|#)?(?#Query)(?:(?:\?(?:[-\w~!$+|.,*:]|%[a-f\d{2}])+=(?:[-\w~!$+|.,*:=]|%[a-f\d]{2})*)(?:&(?:[-\w~!$+|.,*:]|%[a-f\d{2}])+=(?:[-\w~!$+|.,*:=]|%[a-f\d]{2})*)*)*(?#Anchor)(?:#(?:[-\w~!$+|.,*:=]|%[a-f\d]{2})*)?");
private static readonly Regex regexSmilies = new Regex(@"(:\)(?!\)))");

public static readonly DependencyProperty ContentProperty = DependencyProperty.RegisterAttached(
"Content",
typeof(string),
typeof(RTBNavigationService),
new PropertyMetadata(null, OnContentChanged)
);

public static string GetContent(DependencyObject d)
{ return d.GetValue(ContentProperty) as string; }

public static void SetContent(DependencyObject d, string value)
{ d.SetValue(ContentProperty, value); }

private static void OnContentChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
RichTextBox richTextBox = d as RichTextBox;
if (richTextBox == null)
return;

string content = (string)e.NewValue;
if (string.IsNullOrEmpty(content))
return;

richTextBox.Document.Blocks.Clear();

int lastPos = 0;
Paragraph block = new Paragraph();
foreach (Match match in regexSmilies.Matches(content))
{
if (match.Index != lastPos)
block.Inlines.Add(content.Substring(lastPos, match.Index - lastPos));

BitmapImage bitmapSmiley = new BitmapImage(new Uri("giggle.gif", UriKind.Relative));
Image smiley = new Image();
smiley.Source = bitmapSmiley;
smiley.Width = bitmapSmiley.Width;
smiley.Height = bitmapSmiley.Height;
block.Inlines.Add(smiley);

lastPos = match.Index + match.Length;
}
if (lastPos < content.Length)
block.Inlines.Add(content.Substring(lastPos));
richTextBox.Document.Blocks.Add(block);

List<Hyperlink> results = new List<Hyperlink>();
//foreach (Match match in regexUrl.Matches(content.Replace(Environment.NewLine,"")))
foreach (Match match in regexUrl.Matches(content))
{
TextPointer p1 = richTextBox.ToTextPointer(match.Index);
TextPointer p2 = richTextBox.ToTextPointer(match.Index + match.Length);
if (p1 == null || p2 == null)
{
//Donothing
}
else
{
var link = new Hyperlink(p1, p2);
try {
if (p2.GetTextInRun(LogicalDirection.Backward).ToString().Substring(0,7) == "http://") { link.NavigateUri = new Uri(p2.GetTextInRun(LogicalDirection.Backward).ToString()); }
else { link.NavigateUri = new Uri("http://"+p2.GetTextInRun(LogicalDirection.Backward).ToString()); }
}
catch { }
link.Click += OnUrlClick;

}
}
}

private static void OnUrlClick(object sender, RoutedEventArgs e)
{
if (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl))
{
var link = (Hyperlink)sender;
Process.Start(link.NavigateUri.ToString());
}
}

public static TextPointer ToTextPointer(this RichTextBox rtb, int index)
{
int count = 0;
TextPointer position = rtb.Document.ContentStart.GetNextContextPosition(LogicalDirection.Forward).GetNextContextPosition(LogicalDirection.Forward);
while (position != null)
{
if (position.GetPointerContext(LogicalDirection.Forward) == TextPointerContext.Text)
{
string textRun = position.GetTextInRun(LogicalDirection.Forward);
int length = textRun.Length;
if (count + length > index)
{
return position.GetPositionAtOffset(index - count);
}
count += length;
}
position = position.GetNextContextPosition(LogicalDirection.Forward);
}
return null;
}

}
}

on the other hand, I'm testing the code you've told me, and I indicates that the run does not contain the definition of TextProperty, so I'm going to dig a little about it

thank you very much

Hello Carles,

I am attaching the sample project I put together to test the binding functionality so you can use it as a reference.

Hello Maria
thank you very much for all the help you've given me,

now I have the TextBox and RichTextBox binding

all my code is:

namespace RichTextBox_Hyperlink
{
public partial class MainWindow : Window
{
public class Entry
{
public string MyText { get; set; }
}

public MainWindow()
{
InitializeComponent();

CreateItems();
}

public void Change_LeaveTextbox(object sender, RoutedEventArgs e)
{
mytry.Content = "adios";
Entry test = new Entry();
test.MyText = ((TextBox)sender).Text;

this.DataContext = test;

if (TextWithUrl.Visibility == Visibility.Visible)
{
TextWithUrl.Visibility = Visibility.Hidden;
TextLinkUrl.Visibility = Visibility.Visible;
}
}

public void TextLinkUrl_MouseLeftButtonDown(object sender, RoutedEventArgs e)
{

mytry.Content = "hola";
if (!Keyboard.IsKeyDown(Key.LeftCtrl))
{
if (TextLinkUrl.Visibility == Visibility.Visible)
{
TextWithUrl.Visibility = Visibility.Visible;
TextLinkUrl.Visibility = Visibility.Hidden;
}
}
}

private void CreateItems()
{
CreateTextBox();
CreateRichTextBox();
}

private void CreateTextBox() // TEXT FOR COPY TO RICHTEXTBOX

{
TextBox txtInputData = new TextBox();
//txtInputData.Visibility = Visibility.Hidden;
txtInputData.Name = "TextWithUrl";
txtInputData.TextWrapping = TextWrapping.Wrap;
txtInputData.VerticalScrollBarVisibility = ScrollBarVisibility.Hidden;
txtInputData.AcceptsReturn = true;
txtInputData.MouseLeave += new MouseEventHandler(Change_LeaveTextbox);
Stack.Children.Add(txtInputData);
}

private void CreateRichTextBox() //TEXT COPY OF TEXTBOX
{
// Create a FlowDocument
FlowDocument mcFlowDoc = new FlowDocument();
// Create a paragraph with text
Paragraph para = new Paragraph();
// Create a Run and bind its text
Run run = new Run();
run.SetBinding(Run.TextProperty, "MyText");
para.Inlines.Add(run);
// Add the paragraph to blocks of paragraph
mcFlowDoc.Blocks.Add(para);

RichTextBox txtOutPutData = new RichTextBox();
txtOutPutData.Visibility = Visibility.Visible;
txtOutPutData.Name = "TextLinkUrl";
txtOutPutData.IsReadOnly = true;
txtOutPutData.IsDocumentEnabled = true;
//txtOutPutData.SetBinding(TextBox.TextProperty, "TextWithUrl");
txtOutPutData.Document = mcFlowDoc;
txtOutPutData.PreviewMouseLeftButtonDown += new MouseButtonEventHandler(TextLinkUrl_MouseLeftButtonDown);
Stack.Children.Add(txtOutPutData);
}
}
}

AND THE CLASS code of public static class RTBNavigationService IS:

namespace RichTextBox_Hyperlink
{
public static class RTBNavigationService
{
private static readonly Regex regexUrl = new Regex(@"(?#Protocol)(?:(?:ht|f)tp(?:s?)\:\/\/|~/|/)?(?#Username:Password)(?:\w+:\w+@)?(?#Subdomains)(?:(?:[-\w]+\.)+(?#TopLevel Domains)(?:com|org|net|gov|mil|biz|info|mobi|name|aero|jobs|museum|travel|[a-z]{2}))(?#Port)(?::[\d]{1,5})?(?#Directories)(?:(?:(?:/(?:[-\w~!$+|.,=]|%[a-f\d]{2})+)+|/)+|\?|#)?(?#Query)(?:(?:\?(?:[-\w~!$+|.,*:]|%[a-f\d{2}])+=(?:[-\w~!$+|.,*:=]|%[a-f\d]{2})*)(?:&(?:[-\w~!$+|.,*:]|%[a-f\d{2}])+=(?:[-\w~!$+|.,*:=]|%[a-f\d]{2})*)*)*(?#Anchor)(?:#(?:[-\w~!$+|.,*:=]|%[a-f\d]{2})*)?");

public static readonly DependencyProperty ContentProperty = DependencyProperty.RegisterAttached(
"Content",
typeof(string),
typeof(RTBNavigationService),
new PropertyMetadata(null, OnContentChanged)
);

public static string GetContent(DependencyObject d)
{ return d.GetValue(ContentProperty) as string; }

public static void SetContent(DependencyObject d, string value)
{ d.SetValue(ContentProperty, value); }

private static void OnContentChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var richTextBox = d as RichTextBox;
if (richTextBox == null)
return;

richTextBox.Document.Blocks.Clear();

var newContent = (string)e.NewValue;
if (string.IsNullOrEmpty(newContent))
return;

int lastPos = 0;
foreach (Match match in regexUrl.Matches(newContent))
{
if (match.Index != lastPos)
{
richTextBox.AppendText(newContent.Substring(lastPos, match.Index - lastPos));
}

var link = new Hyperlink(new Run(match.Value))
{
NavigateUri = new Uri(match.Value)
};
link.Click += OnUrlClick;

Paragraph para = new Paragraph();
para.Inlines.Add(link);
richTextBox.Document.Blocks.Add(para);

lastPos = match.Index + match.Length;
}

if (lastPos < newContent.Length)
richTextBox.AppendText(newContent.Substring(lastPos));
}

private static void OnUrlClick(object sender, RoutedEventArgs e)
{
if (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl))
{
var link = (Hyperlink)sender;
Process.Start(link.NavigateUri.AbsoluteUri);
}
}

}
}

now the problem comes when I have to pass the text of textbox for my class: "public static class RTBNavigationService" order to format the links and put the event on click ... could you tell me how can I do this?

Hi Maria

hey now gone up to 4.5.2 but still, sige without the binding work for me: S do not understand why, when you're doing run.SetBinding (Run.TextProperty, "TextWithUrl");

There declare that I want this linked element, in my case TextWithUrl, right?

public MainWindow()
{
InitializeComponent();
Closing += (s, e) => ViewModelLocator.Cleanup();
CreateItems();
}

private void CreateItems() {
CreateTextBox();
CreateRichTextBox();
}

private void CreateTextBox() // TEXT FOR COPY TO RICHTEXTBOX
{
TextBox txtInputData = new TextBox();
//txtInputData.Visibility = Visibility.Hidden;
txtInputData.Name = "TextWithUrl";
txtInputData.TextWrapping = TextWrapping.Wrap;
txtInputData.VerticalScrollBarVisibility = ScrollBarVisibility.Hidden;
txtInputData.AcceptsReturn = true;
txtInputData.MouseLeave += new MouseEventHandler(Change_LeaveTextbox);
Stack.Children.Add(txtInputData);
}

private void CreateRichTextBox() //TEXT COPY OF TEXTBOX
{

// Create a FlowDocument
FlowDocument mcFlowDoc = new FlowDocument();
// Create a paragraph with text
Paragraph para = new Paragraph();
// Create a Run and bind its text
Run run = new Run();
run.SetBinding(Run.TextProperty, "TextLinkUrl");
para.Inlines.Add(run);
// Add the paragraph to blocks of paragraph
mcFlowDoc.Blocks.Add(para);

RichTextBox txtOutPutData = new RichTextBox();
txtOutPutData.Visibility = Visibility.Visible;
txtOutPutData.Name = "TextLinkUrl";
txtOutPutData.IsReadOnly = true;
txtOutPutData.IsDocumentEnabled = true;
//txtOutPutData.SetBinding(TextBox.TextProperty, "TextWithUrl");
txtOutPutData.Document = mcFlowDoc;
txtOutPutData.PreviewMouseLeftButtonDown += new MouseButtonEventHandler(TextLinkUrl_MouseLeftButtonDown);
Stack.Children.Add(txtOutPutData);
}

Hello Carles,

I see that the project was built against .NET3.5 and the Text property is not available there. To my knowledge it is added with .NET4 and it could be bound as well. I would suggest you to contact the MSDN support for additional details on this scenario for .NET3.5.

Please do not hesitate to let me know if you have any questions regarding the Infragistics controls.
