IE11 When EmptyMessage is set OnSelectedIndexChanged event fires during every post back and properties SelectedIndex, SelectedItem have wrong values

Set up info:
Telerik version: 2013.2.611.40
Browser: IE 11.0.9600.16476
.NET Framework: 4.0

Symptoms: During Asynch Post Backs when EmptyMessage property is set AND text of the first item is not English (eg. German, Greek) then OnSelectedIndexChange event fires every time although index has not been changed. Further more properties SelectedIndex, SelectedItem and SelectedValue have the wrong values of -1, null and "" respectively

I have prepared a small project to demonstrate the bug but your forum allows only picture format attachments. So here is the test code:

If you remove the EmptyMessage property or you set it to "" everything goes back to normal.
Also if you comment out line line 36 and you uncomment out line 38 so that first Items text is English then every goes back to normal as well. So I think it should be an issue of the EmptyMessage property and the Encoding of the Items text in the JavaScript you are using.

Thank you for your time and I remain to your disposal for any additional info you may need

Hyperlink <a> inserted with onclick and re-onclick

Hello,

We currently use ver. 2012.3.1016.40 and noticed a very strange pattern when the html with links edited by radEditor was saved into database as
<a href="/path" target="_blank" onclick="return false;">some text</a>
or even more weird:
<a href="/path" target="_blank" onclick="return false;" re_target="_blank" re_onclick="return false;">some text</a>

which makes links non-clickable. Not quite sure how that happened, most likely when edited in Chrome.
Is it a known & fixed issue? I could not find any related info the release notes for the next releases.

Thanks in advance.

add zero in numerictextbox field

I have numeric text box like that

<telerik:radnumerictextbox showspinbuttons="true" incrementsettings-interceptarrowkeys="true" incrementsettings-interceptmousewheel="true" labelwidth="120px" runat="server" id="ddStartHour" width="100px" MaxLength="2" MaxValue="12" Value="0" MinValue="0" CssClass="app-input" DataType="System.Integer" >

<NumberFormat DecimalDigits="0" />

</telerik:radnumerictextbox>

Now my numbers can be 0,1,2,3,4,5,6,7,8,9,10,11,12.

But I want to add zero before the numbers which number is less than 10. SO I want to show my numbers like 00,01,02,03,04,05,06,07,08,09,10,11,12.

How can I do that?

THX.

PlaylistSettings tag is not available

Hi Support,

I'm a Sitefinity user and using version 6.3. I'm trying to use telerik:RadMediaPlayer with playlist option. Copied below code from your demo site and telerik:RadMediaPlayer is available and I can play the video, however I could not find any options for playlist inside telerik:RadMediaPlayer tag. The PlaylistSettings tag is not available for me. Also I want to fire my JavaScript function once the video is finished, I could see option for that but that is not working for me.

<telerik:RadMediaPlayer ID="RadMediaPlayer1" runat="server"

Height="360px" EnableViewState="false" Width="640px" AutoPlay="false">

<PlaylistSettings YouTubePlaylist="PL2HUH5okl73JFq_QDyqVq9GCZ0Dd9L0OH"Mode="Buttons" ButtonsTrigger="Hover" />

</telerik:RadMediaPlayer>

Export To Excel

We follow the steps here:
http://demos.telerik.com/aspnet-ajax/pivotgrid/examples/exporting/defaultcs.aspx

But the pivotgrid.exporttoexcel() is not working. We create a button to call this function but there is no file generated as shown in the demo.

Are we missing anything here?

We are using Telerik.Web.UI version 2013.3.1324.40

attach is the code.
