Incorrect text selection when using Browser Zoom

[Richard Ellis]

Hi

We use your RadRichTextBox controls (among others) in our Silverlight application.  Recently we've come across a curious problem.  When Browser zoom other than 100% is applied (occurs in Firefox, and Chrome - other browsers not yet tested), we find that text selection with the mouse is off, and the completely wrong text is selected.

The attached screenshot is the result of selecting the top line 'What is an Etray?' using the mouse at 150% zoom.  Clearly this is incorrect.

We were hoping to use browser zoom to help with accessibility, so it's important we get this sorted out.  Currently we have turned off 'enableAutoZoom' in Silverlight to allow the application to go Live, but this is very much a stop-gap.  We can not leave it like this.

Thanks.

Hi Richard,

Thank you for pointing out this problem.

Incorrect caret positioning and mouse selection problems when RadRichTextBox is used in RadWindow and zoomed browser is resolved for Silverlight 5 version of our assemblies. Unfortunately, the only solution for you could be to upgrade your project to Silverlight 5. Otherwise, as a workaround you could use the zoom functionality of RadRichTextBox to zoom in/out its content instead of zooming the browser.

I hope this information helps. Please, do not hesitate to contact us if you need further assistance.

Kind regards,
Vasil
