Hi Claude Grosjean

Please find attached the source code of the examples.
We will make sure that the files are visible in the demos in the next releases.

I am able to crash the demo that is attached.  Here are the steps:

1.    Select "New" from the application popup menu.
2.    Click "OK" to not save any changes.
3.    A new document is created.  CLick in the left margin of the empty document and the demo application with throw and exception.

I have developed a demo SL4 app that is similar to your attached demo.  However, in my app, I am not seeing the thumb controls showing up in the ruler.  The remainer of the ruler is just fine, but the margin thumbs are not being displayed.

In the demo you attached, I noticed that the PNG files for the ruler thumb controls are actually in the example app under Images\RichTextBox\Ruler.  Can you explain why these need to be included in the app itself, and not the assembly that contains the ruler?  Regardless, even if I put these images in my test app, the ruler is still not being displayed with the margin thumb controls.  I am associating the ruler with the RichTextBox editor control during initialization, and the remainder of the ruler functionality seems to be working perfectly.  Any help would be appreciated.

I have found another minor issue with the RadRichTextBox (or the demo application). 

1.    Select "New" from the application popup menu.
2.    Move the top margin down by selecting the margin thumb on the vertical ruler (left side of window).
3.    The caret for the current insertion point does not move down when the margin is moved.  However, it will move down when the user types the first character.

Great new control!

I have also found that when images are inserted into the RadRichTextBox using the sample application, they appear normal while editing, but are truncated when in Print Preview mode, and when saved to a file.  I have attached a screen image of the image being displayed properly when in the editor, and being truncated when in Print Preview.

Hi GEB,

Thanks for reporting those bugs!
About the issue with the caret -  it should be OK in Q2 version.
As for the printing problem - when exported to HTML the images are base64 encoded within the HTML. However, IE will not display correctly larger images encoded this way. Firefox or Chrome can handle this case. We are currently searching for a better solution and hopefully we will be able to solve this printing issue under IE for the next release (Q2 SP1) Let us know if we can help further with this.

Best wishes,

Hi Alex,

May I know which version of Telerik the below example code is build on, as I got lot of errors most of them are version incompatabilty errors. I am currently using Q2 2010 SP2 of Telerik.

Uday

Hi Udaybhaskar,

The example was prepared for Q2 2010. Quite a few breaking changes have been made since then.
The solution contains an implementation of some dialogs that have been added to the Telerik.Windows.RichTextBoxRibbonUI, but it lacks some of the latest version of the controls. A similar demo can be found here. The source of this Telerik Demo can be viewed by clicking the Source button in the top right corner and is also available for download from your account.
