Telerik RadEditor Memorystream/string Save To RTF
May 21, 2010
The required functionality I am aiming for is to pull out RTF content from a database, edit it through a web interface (with a WYSIWYG editor) and then place the modified text back in to the database (in RTF format).
The control that I am using to do this is Telerik RadEditor (we have a license already for these controls). In the most recent version there appears to be functionality to load in RTF content from a string or a stream, but the only method I can see that is exposed for getting RTF back out is exportToRTF(); this method modified the headers and allows you to save a RTF version of the content you have just edited as a file.
The functionality to convert from HTML to RTF must exist somewhere within their library as you can export a RTF file, but I can not find any publicly exposed methods to pass this in to a stream or a string.
Does anybody know of a way that I can convert the HTML back to RTF using the Telerik libraries without saving out to a file?

I have an issue using Telerik RadEditor with IE (not Firefox, not Chrome and not Safari).
I think that i have a conflicting css style but i have no idea of wich one (tryed to delete most of the styles). I also tryed to add a ContentEditorArea.css.
How RadEditor displays in IE8 (not very different in IE7) :

In the Telerik.Web.UI.xml file I found this entry
<member name="P:Telerik.Web.UI.RadDataBoundControl.Skin">
<summary>Gets or sets the skin name for the control user interface.</summary>
<value>A string containing the skin name for the control user interface. The default is string.Empty.</value>
<remarks>
<para>
If this property is not set, the control will render using the skin named "Default".
If EnableEmbeddedSkins is set to false, the control will not render skin.
</para>
</remarks>
</member>
that says RadControls are using skin named Default..Now what if I want it to be not default ..what if I want it to be some CustomSkin to be rendered and not default skin?? Where do I need to set the value for the skin I wanna use? I don't know much of XML..so asking
Whats this xml file for anyway? Only describing stuff? What IS the purpose of this xml file??
[EDIT]
Tried setting Skin globally in webconfig.xml as mentioned in telerik's website as follows:-
<add key="Telerik.EnableEmbeddedSkins" value="true" />
<add key="Telerik.EnableEmbeddedBaseStylesheet" value="true" />
<add key="Telerik.RadEditor.Skin" value="CustomSkin" />
This is not making any diff! is using default file only.

RADEditor on my page was inheriting Master Page's CSS properties so followed this tutorial to create custom skin..now what I did was...I simply copied the Folder named "Default" under Skins folder and renamed it to "CustomSkin" and added it like in the code above ..thot it would work but it didn't coz now I don't see border on my RADEditor...why is that ? Also it is STILL inheriting properties from Master page's CSS file :(
I didn't change name of any of the CSS files inside "CustomSkin" folder...Also when I added the following inside "telerik:RadEditor"...still problem persisting..
<CssFiles>
<telerik:EditorCssFile Value="~/Skins/CustomSkin/Editor.Default.css" />
<telerik:EditorCssFile Value="~/Skins/CustomSkin/Window.Default.css" />
<telerik:EditorCssFile Value="~/Skins/CustomSkin/ToolBar.Default.css" />
</CssFiles>

<telerik:RadEditor ToolbarMode="Default"
ID="editor1" runat="server" EnableEmbeddedBaseStylesheet="true">
</telerik:RadEditor>
The editor's using Default skin..when I made changes to Editor.Default.CSS file...they didn't reflect on my page..but when I type the following I can see the changes:-
<link href="Skins/Default/Editor.Default.css" rel="stylesheet" type="text/css" />
<link href="Skins/Default/Window.Default.css" rel="stylesheet" type="text/css" />
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<telerik:RadEditor ToolbarMode="Default"
ID="editor1" Skin="Default" runat="server" EnableEmbeddedSkins="true">
</telerik:RadEditor>
Do I HAVE to create a custom Skin file for the changes to reflect ??I dont wanna coz the editor has been used in many files and now linking new custom CSS file in each and every aspx file will be such a pain.. I just want this to be added in the Skin:-
body
{
background-image:none;
background-color:White;
}
What this does is that it makes the background color of the content area white..earlier the content area of the Editor was inheriting background-image property of the Master Page's body tag...ohh and another funny issue is that the Font styles too are inheriting Master Page's properties only..like Heading 2 in the Editor's drop down list has got a background color when I want it to be simple..
So is making custom skin css file the only solution ..How do I get the changes to reflect thru the Default css file only ? I dont wanna create custom class..why didn't the changes reflect ?

In firebug under "Style" its showing the css file as follows when I hover mouse over RadEditor
"http://localhost/myWeb/WebResource.axd?d=WSPnt1ffDvgb4bj2Ii5nA4MecfZdsnZ0wvgLy3HVcihYTy2nMTq7iIu8RlAb7ZMF61e07jisMUNhQZabIxK2kyuxNpeCFqhE3cgnDSm1-Pc1&t=634237829795625000"
In telerik:RadEditor tag ..I haven't specified any property such as Skin=Skin1 or whatever..so its using some default skin...In the Skins folder..there's this folder named "Default" that's got images and css files...Is "Default" what it's using ??? now when I change something in the Default skin's CSS file...changes do not reflect on my page...so how do I find out which css its using ??can't figure out nothing from a path like that
[edit]
For this Editor mainly 3 css files are being used namely Editor.Default.css,Window.Default.css and ToolBar.Default.css..now when I view page source , I can't find refernce to any of these 3 css files...Also in firebug , under "Styles" where that weird css path is shown, its displaying CSS classes like .reToolbar , etc...now ALL the Skins' CSS files have got this CSS class ".reToolbar" ..so how to find out which CSS file's class is this particular ".reToolbar class" ??

foreach (Control control in ContentPlaceHolder1.Controls)
{
if(typeof(Control).Equals(Telerik.Web.UI.RadEditor))
{
label1.Visible = true; label1.Text = "dhchk";
// control.CssFiles.Add("~/styles/myStyle.css");
}
}
Error;-
'Telerik.Web.UI.RadEditor' is a 'type', which is not valid in the given context
Also, is this the correct way to add CSS class to radEditor controls ??
control.CssFiles.Add("~/styles/myStyle.css");
I actually wanna add 3-4 customized classes..how to do that?
also I was wondering if I can add some javascript or something in my Master page that will detect the ALL the radEditor controls and set their css classes ? don't know much of Javascript..how can that be made possible? how do I go about that? but first I want css classes to be set in code behind..what's wrong with the code?
[EDIT]
@Geek..I tried calling like this..is it correct?
Control c = new Control();
DoSomething(c);
now its giving this error in the method:-
The type or namespace name 'c' could not be found (are you missing a using directive or an assembly reference?)
[EDIT]
I do have this namespace added "using System.Web.UI.WebControls;" why this error ??

We are using Telerik RadEditor control in our project and having some problems with its integration with our user documents storage engine. We've implemented custom content provider for Telerik image manager and it shows correct documents in dialog. But in doesn't switch between images while selection. You can see this on this picture. We've tested this behaviour on the blank ASP.NET page without any additional CSS or JS. Rad editor tag could be found below. Please help! Why do this could happen?
<telerik:RadEditor ID="radEditor" runat="server"
ToolbarMode="ShowOnFocus"
ToolsWidth="402"
EditModes="Design"
ToolsFile="~/RadEditor.xml"
Skin="Default">
<ImageManager ViewPaths="IMAGES" EnableImageEditor="False" ContentProviderTypeName="FileStorageContentProvider, App_CODE" />
</telerik:RadEditor>

Telerik people have not replied. It's been three days now so asking here. Anybody who is familiar with Telerik controls please help me out.

My Asp.Net calls a SQL sproc and returns a XML file as a string. This is what I need to do:
- save that string into memory (as a file);
- pop up a dialog box asking the user which path he would like to save the file;
Any samples out there...how do I achieve this task in Asp.Net C#?

I am using the following code to write the contents of a string (converted to a byte array) to the client in ASP.NET/C#
byte[] data = StrToByteArray(strData);
Response.ClearContent();
Response.AppendHeader("content-length", data.Length.ToString());
Response.ContentType = "text/plain";
Response.AppendHeader("content-Disposition", "attachment;filename=" + fileName);
Response.BinaryWrite(data);
Response.Flush();
fileName is the name of the file ending with the file extension (.pgn). However, the file is saved as a .txt file, ignoring the extension that I am giving it. Would this have to do with the Response.Contenttype = "text/plain"? How can I get the Open/Save dialog to display and save the correct (.pgn) filename?
Also, if filename is a string separated by dashes or spaces, when the Open/Save dialog comes up, the filename is not displayed in its entirety but it is truncated where the first dash (-) or space (or comma) is encountered. How can this be remedied?

I have a function that downloads an image from a DB, saves it to a Temp directory and passes the string back to an app that opens it. Ran fine with .NET 2.0, but throws a variety of exceptions in .NET 4.0. (like System.AccessViolationException was unhandled).It somehow seems to relate to the saved file still being locked.

Im generating a PDF file. Normally I send this to the user using a .ashx file, where the user can directly download it from his browser (see that code below).
Protected Function getfile() As MemoryStream
Dim stream As MemoryStream = New MemoryStream
If document.PageCount > 0 Then
document.Save(stream, False)
'Context.Response.Clear()
'Context.Response.ContentType = "application/pdf"
'Context.Response.AddHeader("Content-disposition", "attachment;filename=TicketEZ_tickets_" + eventname + ".pdf")
'Context.Response.AddHeader("content-length", stream.Length.ToString)
'Context.Response.BinaryWrite(stream.ToArray)
'Context.Response.Flush()
Return stream
stream.Close()
'Context.Response.End()
End If
But now I want to send this file as an email attachment...how can I do that? I tried this, but that doesnt work...(Value of type 'System.IO.MemoryStream' cannot be converted to 'String')
Dim att As New System.Net.Mail.Attachment(getfile)
Msg.Attachments.Add(att)

I'm trying to attach a memorystream as an attachment to an email, however the file is always empty. I'm using a streamwriter to write the text in to the memorystream, I then flush the streamwriter and I can see the memorystream has data. However when I attach the memorystream to the email the file is always empty. I can't see what I'm doing wrong. The code is:

I have a form where users can store some data for archived documents. All documents are ONLY in PDF format.
There are 2 things I would like to do:
1. there is a "file path" text box on the form. I would like to open a "browse file dialog" box when user clicks the textbox and then the user browses for the file (file is on the users local machine) and selects it. The full file path should be saved to the textbox as string (e.g. "c:archive2010document11122011.pdf"). Also I would like to "limit" the file browser dialog to only show PDF format files...
2. add a code behind command to open the file from the saved path+name (see 1.) in the user's default PDF viewer (Acrobat or Foxit)

I have a file, a.pdf, stored on a SharePoint server behind Windows authentication. I want to make a.pdf available through another Web app with forms authentication. Basically, link is clicked and up pops the open / save as dialog for the pdf (or other document file) I've set up my HTTPWebRequest and passed credentials, getting my data into a stream (file.GetResponseStream).
I've tried converting the stream to a byte array and then using response.write or response.output.write with no luck (stream not seekable) I've tried using a streamreader and doing a response.write(streamreader.readtoend()) and response.write(memorystream.toarray(),0,memorystream.toarray().length) with no luck (the message received from the server could not be parsed).

I have an small ASP.NET application that reads data from a table and sends it out as an excel attachment in an email message. The data is simply HTML table tr td tagged data. The way I am sending the message is by the following code:
byte[] data = GetData(excelData);
MemoryStream memoryStream = new MemoryStream(data);
mm.Attachments.Add(new Attachment(memoryStream, "info.xls", "text/plain"));
This has been working fine in Excel 2003 but for some reason Excel 2007 keeps trying to convert the whole thing to a formula and I get a "Cell Data too Long" error. I've tried searching but couldn't really find anything specific about why this might be happening in 07 or a simple way to fix it. I know 07 probably handles data a little bit different than 03 but I don't have a lot of time to dedicate to reworking this app if possible.

When I use a RadEditor I want to enable the editor's spell check (working thus far). After a spell check the user can either click on the radmodule (toolbar thing) to either "finish spellcheck" or "cancel." Which is all fine and dandy except the "finish" button causes a postback!! I don't want that at this point!! "cancel" more or less does what I want to happen - I mostly just want a "done" or a way to stop the postback.
I've tried an Update panel but that just grays out the text area after it does the update.
