telerik:RadMaskedTextBox acting funky without Compatibility View

[SSirica]

I have a web site that uses the telerik:RadMaskedTextBox for the input of telephone numbers and social security numbers.  I recently upgraded my machine to IE9 and started observing some odd behavior.  FYI I can reproduce the issue on your Demo site as well.  Here's what I observed.  With the IE broswer not in Compatibility View mode, go to the Input: RadMaskedTextBox: First Look section of your Demo site.  Change the "Select Mask" to SSN.  Set focus to the Input Box.  Start typing a number.  The number will show up then when you type the next number the box will reset and start typing in the 2nd character location totally losing the 1st number that was typed.  Change the browser to Compatibility View and the InputBox works as expected.

I hope I explained this properly so you can reproduce and fix.  If not, let me know and I will try and do some kind of a screen capture video thing to try showcase this issue.

Thanks

Hello SSirica,

I was able to reproduce the issue locally and confirm that RadMaskedTextBox does not behave as expected in this scenario. I have forwarded your report to our developers for further investigation. Unfortunately, I can not provide you with exact estimate about when the problem will be fixed. However, you can follow the status of the issue in our public issue tracking system.

Kind regards,

I'll be honest with you I'm not 100% sure.  I think I might have put code in the web.config to force IE into compatibility mode.  According to Telerik these issues have been fixed in version ASP.NET AJAX 2011.1 413. 

Good luck.
Steve

Hello Gina,

The RadMaskedTextBox typing problems were fixed as follows:

• For IE9 -> in the Q1 2011 SP1 (2011.1.413) release.
• For IE6/7 -> in the Q1 2011 SP2 (2011.1.519) release.

Please ensure that you are using the latter and let me know whether further assistance is needed.

All the best,
Martin

We have been noticing this same issue lately.  When in IE9 in non-compatibility mode, entering in a phone number into the RadMaskedTextBox repeats every number as you type.  I saw this post saying it had been fixed, but we are using the latest version of Telerik controls - 2011.2.915.40.  And it still seems to be an issue for all users.  I would just switch them to compatibility mode, but we have developed the app for non-compatibility mode.

Thanks for your help,
Dusty

Hello Dusty,

I have tried to reproduce the issue utilizing this online example of the product, but without success. Could you please give it a try and let me know whether I miss something obvious?

I also see this behavior in Google Chrome.

Hello Laura,

I have tried to reproduce the issue on this online demo using Chorme 15.0.874.121. However RadMaskedTextBox controls (both single and multiline) behaved as expected. Could you please confirm that?
