Bug property Filter and EmptyMessage RadComboBox with IE11

[Leonid Caceres]

I have an application in ASP .NET Framework 4.0, one page have a radcombobox and this control works fine in IE8, IE9 and IE10 but recently the page was tested on IE11 and the results were not good.

The code for the radcombobox:
<rad:RadComboBox ID="cmbRegWT" Width="100%" style="min-width:230px;" OnSelectedIndexChanged="cmbReg_Change" CloseDropDownOnBlur="true"
ShowDropDownOnTextboxClick="true" runat="server" Height="350px"  MarkFirstMatch="true"
SelectOnTab="true" DataValueField="wtValue" DataTextField="wtDisplayText" 
HighlightTemplatedItems="true" DropDownWidth="400px" OffsetX="0" EmptyMessage="Velg lønnsart"
AutoPostBack="true" Filter="Contains">

BUG1: I've got an error telling me that the selectedvalue is not selected when someone press a ImageButton
(<asp:Imagebutton ID="btnSaveReg" runat="server" Enabled="false" 
ImageUrl="~/Design/Time/regSave.png" OnClientClick="return CheckDayTotals(this);" OnCommand="saveReg" />

). ErrorSFP24.png

BUG2: cmbRegWT list is also cleared for elements when I select another element and return the cmbRegWT. ErrorSFP24-2.png.

I followed the code and the results were:
BUG1: Property EmptyMessage enter in the "cmbReg_Change" event before enter the correct code behind event for the "btnSaveReg".
Enter in two sub code behind instead one.
BUG2: Automatically filter (Filter="Contains") in the combobox when the user back the cmbRegWT and the user thinks that the items were deleted.

This behavior is not correct because this events was firing by this properties. I have RadControls for ASP.NET AJAX Q3 2013, please I need help to solve this issues with Internet Explorer 11. As, I said in earlier versions of explorer works fine.

Well after review all the code I found the bug. It was a problem of version in the combobox the Telerik.Web.UI v2013.2.611.40 doesn't support strange characters like:  "610 - Timelønn (m/pensjon) inkl. i fast lønn" but the version of telerik (Telerik.Web.UI v.2013.3.1114.40) can support it. It seems that the newest version fix this kind of problems.

Thank you for your answer because I notice the answer when I was preparing a mini-project to send in this forum.
