Hi,

I use the viewer inside a tab control and get during design time very often the following error:

InnerException: reference not set to an instance of an object

NullReferenceException: reference not set to an instance of an object

StackTrace

at MS.Internal.XcpImports.MethodEx(InPtr ptr, String name, CValue[] cvDate)

at MS.Internal.XcpImports.MethodEx(DependencyObject obj, String name)

at MS.Internal.XcpImports.FrameworkElement_ApplyTemplate(FramerworkElement frameworkElement)

at System.Windows.Controls.Control.ApplyTemplate()

After I change something in the code and switch bacl to design view, it mostly work until I close and reopen the page again.

What can I check to make it working?

Hi Dan,

I'm using your HtmlRichTextArea in my application because I needed Html saving and loading, but I found out that text alignment set on "Paragraph" tags in the RichtextArea doesn't get saved to Html.

Can you please find a solution to it ^^, because I really need that functionality (especially when writing a right to left language)..

Thanks a lot !!

Hi guys,

Greate control you have guys. Well done. I have some questions though :

1- Is there the ability to insert chunks of UIElement programatically when the RichtextEditor loads or at any given event ?

     for instance : I want to add : "<b>" as a TextBlockPlus and and the text : "some text" as normal TextBlock. I just want to   highlight html tags. I have tried using richTextBox.Children.Add() method but it is giving errors.

2-  Ability for the control to dynamically adapt its width inside a grid Row by giving it a min-width ?

3- Is there an easy way to replace specific text programatically.

Thanks

Thank you for your reply!

here's the xml that got saved into the database:

At the beginning, the developpement was being done on version 3 of silverlight, that's why I had to use version 5.2.7. but after encountring yet another limitation, my boss decided that it should be okay for my project to be ported to version 4, which was quite easy and straight forward.

The limitation we had is that version 5.2.7 of your RichTextBox didn't support writing Arabic (the letters appeared but weren't connected to each other as it should be in arabic), your new version of the control 5.3.2, supported writing arabic, but what I noticed is that selecting and formatting arabic text wasn't working well, when I select the first letter of a word and apply bold to it, the last letter becomes bold instead and exchange places with the first! In addition to that, there's the fact that selection wasn't following letters quite well.

We could have used the new richtextarea included with silverlight 4 which appears to have solved these problems but I couldn't export to HTML, so my final choice was to use your HtmlRichTextArea. I noticed that this control is based on the native one, adding to it loading and exporting HTML.

Actually, I liked your RichtextBox better because it's much more flexible and easy when it comes to formatting. The HtmlRichTextArea was very limited in its formatting capabilities, and I'm even having problems with text alignement right now (If I change the alignement of some text, when I go to the next line with a return, the alignement of the new line doesn't persist and it turns back to left aligned).

I hope I wasn't very exhausting, but I think my feedback will keep you more informed, so that your controls will become even more useful to everyone.

Thank you for your help!! ^^

Is there a way to store the new words in the cookies or something?  I implemented the spell checker for the rich text box, but it can't remember my words.  I can't really write it to the .xap file.  I would guess a cookie, or isolated storage?  So when you add a new word, I should probably add code to write to that location.  Then when the list is called up, it reads from the isolated storage and the dictionary file?  Is this a good way to do it?

I want each user to have their own additional words on their computer.

Hi Bryan,

In the current version no.  The RichTextBox uses an XML reader to process the HTML so your HTML must be XHTML formatted.  If a tag is encountered that is not supported the RichTextBox should ignore it by default.

Thanks!
