[bob thomash]

Hello Friends !

I m using visual studio 2010 Ultimate with Silverlight 4.
I m using RIchTxtBox as my email Body in my silverlight Project.

I want to Save RadRichTextBox Text in my database as HTML format

how to convert RadRichTextBox Text into HTML???
Please send me sample Code or project

Hi bob thomash,

Currently RadRichTextBox supports only plain text and XAML formats. We will be adding more formats like HTML, RTF for the official version in Q2. Let us know if we can help further at this point.

Any idea on when/if you will be adding support for DOC, DOCX, ODT or PDF?

[Mike]

Hello Glenn Morton,

The DOCX and PDF formats are with higher priority in our plans. Docs will most probably be supported in Q2 and PDF soon after that. For now we are concidering ODT and DOC  (WordML) formats for Q3 release.

Hi,

Please let me know if HTML format is supported in RichTextBox now..?

thanks..

[Ivailo Karamanolev]

Hello Nikhil Thaker,

Yes, HTML export and import is supported by RadRichTextBox. To access it, you'll either have to use RadRichTextBoxRibbonUI, which provides Save/Load functionality out-of-the-box or use HtmlFormatProvider class found in the assembly Telerik.Windows.Documents.FormatProviders.Html. Let us now if you need any further assistance.

Are there any sample applications that demonstrate how to do this (export in HTML format and bind to a database field) as I haven't been able to find any??
Thanks

[Charles Bates]

Hello,
We have many user-editable objects in our application.  We need to serialize/de-serialize them frequently, as well as compare the RadRichTextBox's content with the ViewModel's representation.
What is the most-straightforward way to do that?  It seems rather cumbersome to have to continually go through all the steps required to use the HtmlFormatProvider.

Thanks for any information, and perhaps a sample...

Hello C. Bates

Concerning the data binding, for SP1, which is coming this week, we have developed some supplementary classes that will allow you to bind the HTML, XAML or Text of a RadRichTextBox's document to a database field (or anything bindable in that sense). All this can happen directly in XAML, or in code behind.
In Q2 you had to do the exporting yourself using HtmlFormatProvider and SP1 is to amend that. As it's coming in the next few days, we hope that's not going to reflect badly on your schedule.

And regarding user-editable objects - currently, you can insert any control using InlineUIContainer, unfortunately, the serialization for this doesn't work. As a workaround you can serialize and reinsert the elements as you save the document. A fix for this will be available for Q3 and users will be able to provide their own serialization logic.

Please let us know if you need any further assistance.

Best wishes,

So... Are there samples or demos of how to use RichTextBox now with the HTML format?

[Ivailo Karamanolev]

Hello Travis,

Here's the newest demo showing how to use DataProviders with RadRichTextBox:
http://demos.telerik.com/silverlight/#RichTextBox/Binding

And here - the help article that will give you some insight into the methodologies:
http://www.telerik.com/help/silverlight/radrichtextbox-how-to-binding-to-data-providers.html

Here's a small snippet that contains two methods: one that takes a HTML string and returns a document (which you can later assign to RadRichTextBox) and one that takes a RadDocument and returns an HTML string:

RadDocument FromHtml(string html) {
    return new HtmlFormatProvider().Import(html);
}
string ToHtml(RadDocument document) {
    return new HtmlFormatProvider().Export(document);
}

It's up to you to choose one from the options: either use HtmlDataProvider to bind the HTML text directly to something else, or manually use HtmlFormatProvider from code-behind.
I hope this helps.

Kind regards,
Ivailo

Hello,

RTF format is supported now by the RadRichTextBox?
If not, it will be available soon?

Thanks

[Iva Toteva]

Hello Mircea,

RTF support is not supported for now. It has been scheduled for Q1 2011, which is due around April next year. You can find information on the currently supported file formats and examples on their usage in this help article.
If you have other questions, do not hesitate to contact us again.

Sincerely yours,

Hi, Ivailo.

I would like to ask about this line of code here: [one that takes a HTML string and returns a document (which you can later assign to RadRichTextBox)]

RadDocument FromHtml(string html) {
    return new HtmlFormatProvider().Import(html);
}

does is have any restrictions on the string literals?
i tried to set the string  to the HTML file I exported coming from the RadGridView but nothing happens.

<table style="border-collapse:collapse" border="1">
<tr>
<td style="width:45">ID</td><td style="width:113">CategoryName</td><td style="width:212">Description</td><td style="width:79">Quantity</td><td style="width:58">Price</td><td style="width:273">AdditionalDetails</td></tr>
<tr>
<td>1</td><td>Kayaks</td><td>Traditionally used by hunters</td><td>5</td><td>1999.99</td><td>asdfghjklasdfghjkl;asdfghjkl;asdfghjkl;sdfghjkl;</td></tr>

<tr>
<td>2</td><td>Canoes</td><td>Small, narrow, human-powered boat</td><td>6</td><td>1999.99</td><td>asdfghjklasdfghjkl;asdfghjkl;asdfghjkl;sdfghjkl;</td></tr>
<tr>
<td>3</td><td>Dinghies</td><td>Small boats, 2-3 meters long</td><td>7</td><td>1999.99</td><td>asdfghjklasdfghjkl;asdfghjkl;asdfghjkl;sdfghjkl;</td></tr>
<tr>

<td></td><td></td><td></td><td></td><td></td><td></td></tr>
</table>

is there a solution to this?

[Iva Toteva]

Hello Angeli,

The problem with the file is that the styles of the table cells specify widths without a measuring unit (which is invalid according to the CSS specification). If you add a measuring unit, e.g. 

<td style="width:45px">

the HTML will be properly imported.
We have adjusted our import, so that if no measurement unit is appointed, pixels are inferred, although the CSS standard states that a unit must be present.

[Олег]

Hello!
I wanted to exclude all attributes when serialize td like this: <td>... and so on.
Its explained there: http://www.telerik.com/help/wpf/radrichtextbox-features-import-export-settings.html
I added to ignores these properties:

htmlExportSettings.PropertiesToIgnore["td"].Add("border-top");
htmlExportSettings.PropertiesToIgnore["td"].Add("border-bottom");
htmlExportSettings.PropertiesToIgnore["td"].Add("border-left");
htmlExportSettings.PropertiesToIgnore["td"].Add("border-right");
htmlExportSettings.PropertiesToIgnore["td"].Add("padding");
htmlExportSettings.PropertiesToIgnore["td"].Add("vertical-align");
htmlExportSettings.PropertiesToIgnore["td"].Add("align");

And result is:
<td align="left" valign="top">...  =>  <td>...

What's wrong?

[Mihail]

Hello Oleg,

Thank you for contacting us.

I can confirm that there is a problem with ignoring the export of attributes for table cell in html format.
I have opened bug report item in our feedback portal where you could track the overall progress of the issue.

Please excuse us for the inconvenience.

On a side note we made some improvements in our help documentation. If you are interested you can check it at RadRichTextBox help for Silverlight or WPF.
