Hi,

after the last update (2013.1.403.40) we noticed a changed behaviour on the RadDateTimePicker component. If the user does not tab out from the component or goes to another input field before he does a callback the SelectedDate is null.

I'm pasting in a test project

Best regards

Robert

Thanks for yourt suggestion, but unfortunatly this solultion is not possible with a live web place with many aspx pages and many RadDateInput and RadNumericTextBox components.

We upgraded to SP1 to get rid of a similar problem regarding RadTextBox on Windows Phone devices.

1) When do you estimate to have a fix for the problem?
2) Is the orginial Q1 2013 available for download and if so where can I do it?

2013-05-14 Update
I tried Teleriks suggestion to manually focus another element before doing the postback. I added java for the OnClientTabSelecting on my menu (a RadTabStrip) but this change did not solved the problem.

Please Telerik - can you give us a hint when you estimate to have a solution for the problem!

Best regards

Ok, I have a fix for the problem but is really ugly and I hope that someone at Telerik soon can reply on my questions

1) When do you estimate to have a fix for the problem?
2) Is the orginial Q1 2013 available for download and if so where can I do it?

Sorry for the double post but your site did not operate well yesterday. When I was trying to att my code-block and save the post, the page returnes and the thread untouched.

I used the GAC to restore the Telerik dll's and tried it with Q1 2013 (both original, SP1 and SP2) and recreated the error on all versions. The previous version that we used and where our pages behaved as predicted was in Q1 2011 (2011,3,1115,40).

To sum up the error:

Telerik version: Q1 2013
Browser where the problem is found: IE 9, IE 10, Firefox 19, Opera 12
Browser where the problem is NOT found: IE 6, IE 7, IE 8, Chrome 26,
Component: RadDateTimePicker and RadNumericTextBox
Description: Using the above components together with RadTabStrip (and perhaps other componts that uses callback) without first leaving the component results in data loss. For the RadDateTimePicker the date disappears and in the RadNumericTextBox the decimal point disappear.
Work around: Use the OnClientMouseOver event on the RadTabStrip (Telerik suggested the OnClick event which does not exists) and bluring the component

Now you have a detailed description of the error, let us hope that I get fix in Q2 2013

Kind regards

Robert
