     This is a Rich Text Box for ASP .NET. You can copy information from a word document into it and it will keep the format and save it to a database for display on the web. This is built into VB .NET but there is nothing out there for ASP .NET. After doing some searching and comming up with nothing we decided to make our own and share it with everyone. You can also format the text with the controls built into the Rich Text box. Example Bold, Underline, Change the color, center, etc.

Absolutely brilliant from what I've seen so far - this is by far the most useful code I've come across on this site.

One nice to have would be to convert this into a User Control - but I might just do that myself. The full 5 from me.

PS - Calvin and Hobbs, nice!

I have been looking for such RichText editor. Its great. It will be very easy if we convert this to a user control like the EasyWebEdit. If could convert it to user control I will share it here.

Thanx for sharing your knowledge.

In reply to your problem:

it is an error in the HTML at the top of the ASPX page.

it should read:
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="RTB.aspx.vb" Inherits="RTB.WebForm1"%>

not:
Codebehind="Global.asax.vb"
Inherits="RTB.Global" %>

Hope this helps.

Great Work,
can you also add an "Add table" and "add row/column" to the selected table it would very very good,

another thing, if i paste a local word text with images lets say, and saved it to a database , how can i display the images? the src is pointing to the local machine, and i am viewing them from another machine, do you have any idea?

(If this comment was disrespectful, please report it.)
 
5/12/2004 10:27:46 AM: Daniel Bertram

In reply to your question: how can i
display the images?

You would have to check the edit HTML box and edit the location of where you are going to upload the files to. Then upload the images to your host.

Thanks,

Dan

5/13/2004 4:25:37 AM: Basel Nimer

Thanks,
Yes, i thought of that, but there is no way to upload the images without the user selecting them, no ?
I mean, because of the security restrictions of IE,

Is there a way to upload them automatically ?

Another thing, I tried to convert this to a user control, and everything worked good, but the dlgHelper, I keep getting a "dlgHelper is Undefiened" Javascript error , any Ideas?

Thanks Agaian, If this dlgHelper thing works, i'll send you the new usercontrol.

it worked, i have it now as a UserControl

I am waiting to solvethe Images Issue.

5/13/2004 9:50:32 AM: 

You are probably going to have to add the file upload control to the page and just add the html code as stated before to the rich text box to display the file. Hope this helps.

I decided to use this editor because it seems very powerful, but when I run RTB.aspx I received the error:
Could not load RTB.Global, in the first line of global.asax.
<%@ Application Codebehind="Global.asax.vb" Inherits="RTB.Global" %>

I did the changes mentioned above and another problem "Could not load RTB.WebForm1" comes.

Does anyone face the same problem? Please help.

Thanks.

9/17/2004 7:17:57 PM: 

OK, I found the problem:
Could not load RTB.WebForm1".
I just re-build the project using The Visual Studio to create the dll.
The database problem "Could not lock file." still coming. I replaced the mdb file with new one with full access for all users and still the sanme err message comes. Any one can help?

Thanks.

The default web access mode for this project is set to file share, but the project folder at 'http://localhost/RTB' cannot be opened with the path 'c:\inetpub\wwwroot\RTB'. The error returned was:

4/20/2005 10:51:33 AM: 

Okay I feel like a fool now, ever notice how the small things you over look are exactally the things that are wrong, when the dlgHelper is called in the javascript it should have a document. in front of it in order for it to function inside of form tags. Just figured I would post this solution for anyone else who happens along this page.

Dan, Mark... beauty, guys!

To ppl who were having problems:
Put the project in the specified location. Open with VS.NET. It asks to convert to the current version (2003), so let it. Run it, but the db problem's still there. So follow the steps given. Some of you may be saying 'but I don't have the Security tab!' To fix that, go to Windows Explorer: Tool>>Folder Options>>View>>uncheck Use Simple File Sharing. The proceed with the rest of the steps and voila!

Big big thankyou!! This is possibly the most useful piece of code I have ever downloaded. I re-wrote the VB to query and update records from an sql datasource. In the past, my application required the user to manually code HTML if they wished to break the pages data formatting for a record. This is so much easier for them!

Thanks again.

Text representing URLs and the mailTo are being converted to links - but appear to be non active - ie nothing happens when I click on them - do I have a problem with the helper objects ?

This is the way to solve the problem: "A potentially dangerous Request.Form value was detected from the client"

for example if you already have:

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="MyForm.aspx.vb" Inherits="Proj.MyForm"%>


then this should become:

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="MyForm.aspx.vb" Inherits="Proj.MyForm" validateRequest="false"%>

Love the code and it works great in IE but cant seem to get it to work in FireFox. By not work I mean none of the option buttons work and the editor field is not populated and cannot be clicked on to add text. Any thoughts? I would love to get it working in FF.

I guess we need to find "img src"tag and then upload the file in that address to the server.Then replace this address with our upload address with some string manipulators.These lines are needed to be like that , else it would be a problem if we tried to copy & paste a word file into this page.Other than this , it's a very high level work , i think.
