Inserting custom made links into RadTextBoxControl

Hi Dinko,

Thank you for taking the time to look at this.  To create a little sample app, create a test project, add a radform and radtextbox, add a button if you like. I used .net core project, so in the .net6-windows folder, create a test file called test.cmd. Fill it with this:

@echo off
@echo This line has no links
@echo This line has no links
@echo "This line some links <link cmd=SomeCommand>Click me</link>"
@echo this line has no links.
@echo "This line some links <link cmd=Another command>Click me</link>"

Then, in your form's code window, use the following code:

using System;
using System.Diagnostics;

namespace LinkTest
{
    public partial class RadForm1 : Telerik.WinControls.UI.RadForm
    {
        public RadForm1()
        {
            InitializeComponent();
        }

        private void RunProcess()
        {
            RichTextBox.Text = String.Empty;

            Process proc = new Process();

            proc.StartInfo.FileName = "test.cmd";

            proc.StartInfo.UseShellExecute = false;

            proc.StartInfo.WindowStyle = ProcessWindowStyle.Minimized;

            proc.StartInfo.CreateNoWindow = true;

            proc.StartInfo.RedirectStandardOutput = true;

            proc.OutputDataReceived += OnDataReceived;

            proc.Start();

            proc.BeginOutputReadLine();

            proc.WaitForExit();

        }

        private void OnDataReceived(object sender, DataReceivedEventArgs e)
        {
            var line = e.Data;
            if (line != null)
            {
                RichTextBox.Insert(line + Environment.NewLine);
            }

        }

        private void RunButton_Click(object sender, EventArgs e)
        {
            RunProcess();
        }
    }
}

My goal was to parse out the <link> tags and replace them with real hyperlinks that I can handle in code behind.

Hope that helps clarify it. Thanks again for looking at this.

Thank you for the additional details.

What I can suggest covering your scenario is to use our RadRichTextEditor control. The control display and edits rich-text content, including formatted text arranged in pages, paragraphs, spans (runs), tables, and as in your case hyperlinks. You can check the following articles which I think will help you start with the control:

• Getting Started
• Document Elements
• Hyperlink

For your convenience, I have created a sample project to demonstrate what I have in mind. I have slightly modified the text file so that it includes the actual URL address.

@echo off
@echo This line has no links
@echo This line has no links
@echo "This line some links <link cmd=www.telerik.com>Click me</link>"
@echo this line has no links.
@echo "This line some links <link cmd=www.google.com>Click me</link>"

Here is the result from my side:

Hi Dinko,

I was able to get this to work partially. If you add any additional text immediately after inserting a hyperlink, the color of the font will be changed to black. I don't know why it does this and I couldn't find any work around. In my app, my rich text editor is a dark grey color (visual studio theme) with white text. I gave up on trying to implement the links for now. 

Thank you again for taking the time to help me on this. Your time is appreciated.

Regards,

Michael

Hello Michael,

I have tested your approach but the color of the hyperlink is not changed to black. I have tested it on my side but wasn't able to reproduce it.

If you send me a sample project which demonstrates the described behavior I could take a look on my side. 

I am still confused about what is not working. Any string different from the hyperlink and placed afterward will have the same font. I have used the VisualStudio2012Dark theme and the result is expected, at least in my mind. 

Here is the code which I used to add more text. Maybe you are using a different approach.

this.radRichTextEditor1.Insert(text);
this.radRichTextEditor1.InsertHyperlink(info, "Click me");
this.radRichTextEditor1.Insert(" "+"Some Text Here");

The code is from the attached project. Can you send me pictures of what you are expecting and what is the result of your application? You could modify the project if you are using a different approach.
