Using the microsoft word,In docx document,inserting a shape,and add the text context to the shape,then save.

when radrichtextbox  open the file,the program crashed.

I have no idea how to reproduce this, but every so often after a paste operation into a RadRichTextBox, the host thread becomes unresponsive to user input. The message pump is still running but the following unhandled exception gets thrown in a tight infinite loop. The only way to close the window is to right click on the taskbar button.

System.NullReferenceException
Message: Object reference not set to an instance of an object.

To reproduce:

• Create two lists one after another
• Select the second by using the keyboard 
• Press delete and then Ctrl+z (undo)

This works fine when the list is selected with the mouse. 

When importing from a .docx the RichTextBox is adding a blank line for each continuous section break. You can see this in the attached file - in the RichTextBox there is an extra line between sections that does not exist in the source word document.

This can be reproduced with the provided .docx. In Word the image floats in the empty space below the text but the RichTextBox has it inline and overlapping text.

Removing the rectangle from around the image in the source document has no affect.

Hi support,

We have a problem when we copy a text from MS word to RitchTextBox.
If the text copied uses an style that the namecontains tilde, then style name on the ritchtextbox is broken with strange characters.
All works well with this strange characters, but if you export to html and then import to ritchtextbox, the style is lost ...

This is a big problem because in spanish, many styles have tildes. When our user copy content from word they have problem with html format export / import.


I Attach a MS Word docx with a style with tildes:

Steps to reproduce it:

1- Open MS Word attached.
2- Copy the content.
3- Open a ritchTextBox Editor
4- Paste the content.
5- Export to html
6- Import the html.

You can see now, that the style are lost, and the name of the style contains strange characters.

Similar issue its happen when open a Word Docx with styles with tildes from ritchTextBox, not include strange characters but the style is lost.

Thanks for you support,

Hi Guys,

Our application works with a document storage and we use RadRichTextBox to allow users edit and view the documents. Unfortunately, many documents cannot be opened due to the following exception we get:

Unable to cast object of type 'Telerik.Windows.Documents.Model.FieldRangeStart' to type 'Telerik.Windows.Documents.Model.AnnotationRangeEnd

As result we receive complains from our users. Could you please facilitate with solving it? 

I have attached a simple test application with the problematic document as well the stacktrace. 

Best regards,

Yaroslav 

Hi Telerik,

We are converting XAML content into PDF file with below code.

private byte[] Xaml2Pdf(string xamlContent)
{
	try
	{
		XamlFormatProvider xamlFormatProvider = new XamlFormatProvider();
		PdfFormatProvider pdfFormatProvider = new PdfFormatProvider();
		PdfExportSettings exportSettings = new PdfExportSettings();
		exportSettings.ContentsCompressionMode = PdfContentsCompressionMode.Automatic;
		exportSettings.ContentsDeflaterCompressionLevel = 9;
		exportSettings.DocumentInfo = new PdfDocumentInfo() { Producer = "ALIS", Author = "ALIS", Creator = "ALIS" };
		exportSettings.ImagesCompressionMode = PdfImagesCompressionMode.Automatic;
		exportSettings.ImagesDeflaterCompressionLevel = 9;
		pdfFormatProvider.ExportSettings = exportSettings;

		byte[] content = pdfFormatProvider.Export(xamlFormatProvider.Import(xamlContent));

		return content;
	}
	catch
	{
		throw;
	}
}

Adding bookmarks with the same name programmatically always returns the first one in case use attempts to navigate to it using the Bookmarks dialog. 

Workaround: Remove the bookmark before adding a new one with the very same name.

Open a docx file in richtextbox, if numpages in headers do any subtraction, it can not display correctly. see the attached pictures for how to display in richtextbox and microsoft word 2016.

When cross-reference is added in the header/footer of a document in does not show the available options from the document.

I think my bullets having different pattern which outlook 2013 doesn't support.
Do i need to add any other property background position : inside; something like.


Please find the attachments,

As a result RadDocument instances cannot be collected by the GC.

When the user enter text using the keyboard the PositionChanged event of the CaretPosition is not fired.
The item's status changed to Declined - the LocationChanged event can be used to track when the location of the position has been changed.

StackOverflowException is sometimes thrown while a document containing annotations is updated in the main thread (e.g. by typing in it), and spell checking is enabled.

The exception is thrown in a background thread, which call stack similar to this one:

We have a legacy system that generates RTF using some native RTF controls. The RTF generated by this application is compatible with MS wordpad. But seems that the RadRichTextBox is not compatible. The problem is when we use bullets.

Consider we create an RTF with bullets, using legacy -

   * Legacy Bullet 1
   * Legacy Bullet 2
   * Legacy Bullet 3

Then, this is the RTF that is generated -

{\rtf1\fbidis\ansi\ansicpg1252\deff0{\fonttbl{\f0\fnil\fcharset0 Segoe UI;}{\f1\fnil\fcharset0 Arial;}{\f2\fnil\fcharset2 Symbol;}}

{\colortbl ;\red0\green0\blue0;}
\viewkind4\uc1\pard\ltrpar\cf1\lang1033\f0\fs22\par
\pard{\pntext\f2\'B7\tab}{\*\pn\pnlvlblt\pnf2\pnindent0{\pntxtb\'B7}}\ltrpar\fi-200\li200\tx360 Legacy Bullet 1\par
\pard{\pntext\f2\'B7\tab}{\*\pn\pnlvlblt\pnf2\pnindent0{\pntxtb\'B7}}\ltrpar\fi-200\li200\tx360\tx360 Legacy Bullet 2\par
\pard{\pntext\f2\'B7\tab}{\*\pn\pnlvlblt\pnf2\pnindent0{\pntxtb\'B7}}\ltrpar\fi-200\li200\tx360\tx360\tx360 Legacy Bullet 3\par
\pard\ltrpar\tx360\tx360\tx360\par
\f1\par
}
----------------------------------------------------------------------

Now, if we open this RTF in Wordpad, then the bullets are displayed correctly.

But the bullets are not displayed when we bind the RTF to RadRichTextBox.

It displays something like this -

Legacy Bullet 1
Legacy Bullet 2
Legacy Bullet 3

And after binding the original RTF, if we now try to get the RTF this is how it looks like - 

{\rtf\ansi\ansicpg1252\uc1\deff0\deflang1033{\fonttbl{\f0 Verdana;}{\f1 Segoe UI;}{\f2 Arial;}}{\colortbl\red0\green0\blue0 ;;}{\*\defchp\ltrch\f0\fs24\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone}{\*\defpap\sl276\slmult1\sa180}{\stylesheet{\s0\sqformat\spriority0\ltrch\f0\fs24\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone\sl276\slmult1 Normal;}{\*\ts2\tsrowd\spriority59\trbrdrt\brdrnone\trbrdrb\brdrnone\trbrdrl\brdrnone\trbrdrr\brdrnone\trbrdrh\brdrnone\trbrdrv\brdrnone\trgaph0\clpadft3\clpadt0\clpadfr3\clpadr0\clpadfl3\clpadl0\clpadfb3\clpadb0\tsvertalt\ltrch\f0\fs24\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone\sl276\slmult1 Table Normal;}}\nouicompat\viewkind4\paperw12240\paperh15840\margl1425\margr1425\margt1425\margb1425\deftab720\sectd\pgwsxn12240\pghsxn15840\marglsxn1425\margrsxn1425\margtsxn1425\margbsxn1425\headery720\footery720\pard\s0\ltrpar\sl240\slmult1{\ltrch\f1\fs22\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone\par}\pard\s0\ltrpar\tx360\sl240\slmult1\li200\lin200\fi-200{\ltrch\f1\fs22\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone Legacy Bullet 1}{\ltrch\f1\fs22\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone\par}\pard\s0\ltrpar\tx360\sl240\slmult1\li200\lin200\fi-200{\ltrch\f1\fs22\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone Legacy Bullet 2}{\ltrch\f1\fs22\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone\par}\pard\s0\ltrpar\tx360\sl240\slmult1\li200\lin200\fi-200{\ltrch\f1\fs22\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone Legacy Bullet 3}{\ltrch\f1\fs22\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone\par}\pard\s0\ltrpar\tx360\sl240\slmult1{\ltrch\f1\fs22\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone\par}\pard\s0\ltrpar\tx360\sl240\slmult1{\ltrch\f2\fs22\i0\b0\strike0\cf0\cb1\highlight1\ulc0\ulnone\par}}

A NullReference exception is thrown when the content of a MS Outlook mail is copy/pasted into RadRichTextBox. 

This is reproducible in Paged LayoutMode.
