I'm noticing the same issue after updating my solution to the latest update (2012.1.215.40)
Any solution or suggestion?

Best regards

Hi Luca,

I think telerik have no time their users. But i have found some problems in their updated version like if you used the style sheet manager on your page or your master page than please remove that and check your application. and one more thing is that if you have made any default focus on RadDatepicker than please remove Raddatepicker.Focus(). I think all these problems occurring in raddatepicker and radtext box.

Hope this help you.. :-)

Thanks
Manish

Hello,

The issue was that in some conditions wrong format of the date was pass to the sever, and it was not parsed correctly. This was solved several weeks ago and it should work correctly in the latest internal builds. We are also working on some improvements for transferring and parsing the selected date for RadDateInputs and RadDatePickers.
Currently If you have problems with submitting the date when the inputs is in focus and another script or controls is making the callback, it would be best to set EnableSingleInputRendering property of your inputs to "false" and it should work correct in all cases. Meanwhile we are working on some fixes that will allow to submit the proper value of the control regardless of its focus state.
