We are seeing a JavaScript error when we select an Option in a Select control with a ASP Postback on IE11 via keyboard input.
<%@ Page Language="C#" AutoEventWireup="true" Inherits="System.Web.UI.Page" %>
<script runat="server">
    void Page_Load(object sender, EventArgs e)
        decorator.DecoratedControls = FormDecoratorDecoratedControls.Select;
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<title>DD Test Page</title>
<form id="DialogForm" runat="server">
    <telerik:RadScriptManager runat="server" />
    <telerik:RadAjaxManager runat="server" />
    <telerik:RadFormDecorator ID="decorator" runat="server" DecorationZoneID="Panel1" EnableEmbeddedSkins="false" RenderMode="Lightweight" />
    <telerik:RadAjaxPanel ID="Panel1" runat="server">
        <asp:DropDownList ID="DD1" runat="server" AutoPostBack="true">
            <asp:ListItem Text="[Select]" Value="" />
            <asp:ListItem Text="T1" Value="1" />
            <asp:ListItem Text="T2" Value="2" />
        <asp:Button runat="server" Text="Refresh" />
Reproduce by clicking the DropDown control, and then pressing 'T', and then clicking on a blank section of the page.

You can get the same behavior that all other browsers get - focus being after the table. This is done easily by clearing out the following function logic (make sure the script is after the script manager):

   Telerik.Web.UI.Editor.TableDeleteRow.prototype.selectAnotherRow = function () { }

You can also try the following version of the function that attempts to fix the selection collapse after the DOM changed:

Telerik.Web.UI.Editor.TableDeleteRow.prototype.selectAnotherRow = function (layoutBuilderEngine) {
    if ($telerik.isIE9Mode) {
        var arStateIndexes = layoutBuilderEngine._getLeftTopStateIndexes(layoutBuilderEngine._selectedRowIndex, layoutBuilderEngine._selectedCell.cellIndex);
        var stateRow = arStateIndexes["rowIndex"];
        var nextCell = layoutBuilderEngine._getSelectedTableCellByStateIndexes(stateRow + 1, 0);
        var prevCell = layoutBuilderEngine._getSelectedTableCellByStateIndexes(stateRow - 1, 0);
        var newSelectedCell = nextCell || prevCell;
        if (newSelectedCell) {
            var editorSelection = this.get_editor().getSelection();
            setTimeout(function () {
                try {//the DOM change is likely to cause errors after the fixes, hence the try-catch, the timeout is to let the DOM get changed before tampering with the selection
                    if ($telerik.$(newSelectedCell).is(':visible')) {//for deleting footer cells
                        editorSelection.moveToElementText(newSelectedCell);//to properly move focus
                catch (ex) { }

Considering the drawbacks of fixing IE code that is also inconsistent with other browsers, it is possible that the final fix will be to remove the function and have the same behavior as in other browsers.

We have telerik Radgrid on the pages in our application. When viewed in the windows phone 8 browser the horizontal touch scroll does not work. Moreover the color of the scrollbar is almost invisible. Requests anyone to please suggest how to overcome this issue. we tried providing a skin as "Balck Metro touch" and also tried enabling "embedded skins" but none of this works.

There is a bug with the "Play" parameter while I insert a SWF movie.
If I uncheck this parameter, the movie still play in Chrome/Mozilla.
This bug is  from this parameter that isn't added in the Embed tag although it is in the object tag.

Example :
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="150" height="150">
<param name="Movie" value="/aspnet-ajax/Editor/images/UserDir/Marketing/Reporting_banner.swf">
<param name="play" value="false">
<param name="quality" value="high">
<param name="wmode" value="transparent">
<param name="loop" value="false">
<param name="menu" value="false"><embed src="/aspnet-ajax/Editor/images/UserDir/Marketing/Reporting_banner.swf" width="150" height="150" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" quality="high" wmode="transparent" loop="false" menu="false"></object>

Thanks a lot

Update: Items is marked as Won't Fix as the behavior is expected and is due to the nature of the batch mode. Changing it will result in a breaking change.

Uploaded jpeg images cannot be edited in ImageEditor from the Image Manager dialog. The request for the file seems accurate, but the image is not rendered.

I updated my code with version 2013.3.1114, but the method get_cell() of the GridDataItem has become case-sensitive.
I have some codes that with version 2012.3.1016 that was working correctly.
Is possibile to have the choice of case-sensitive / insensitive or at least have backward comaptibility ?

Important: The issue only occurs when the Buttons are spread around in different rows in RadGrid.

When multiple RadButtons (ButtonType="ToggleButton" ToggleType="Radio") are grouped through GroupName property, the server-side property checked doesn't take effect when the button which is to be checked is declared before the current checked button. The workaround is to execute JavaScript from the server which sets the checked property. For example: C#: string script = "function f(){$find(\"" + RadButton1.ClientID + "\").set_checked(true); Sys.Application.remove_load(f);}Sys.Application.add_load(f);"; ScriptManager.RegisterStartupScript(this, this.GetType(), "key", script, true);

The long code lines in the QSF code viewer are very hard to read as the only way to get the horizontal scroll-bar is to reach the bottom of the page.

Using the client-side requestItems method of a RadComboBox to fire the refresh of it's items(with a call to clearCache before to ensure that the refresh is performed), doesn't always perform the async callback request, sometimes resulting in the "Loading" text being added at the top of the combo's items drop-down and staying there (as the callback to the server is never fired, so it's result never received). 

After quite a bit of trials, I finally managed to figure out that the issue arise when there is an async postback in progress on the page (to refresh an update panel) when requestItems is called.

Stepping through the requestItems call with IE F12 tools, I found that this is due to the fact that the Sys.WebForms.PageRequestManager do not perform callbacks if there is an async postback in progress. I think that the RadComboBox should detect that situation and wait until the end of the async postback to fire it's requestItems callback, otherwise the combo get stuck in the "loading in progress" state, waiting for the end of the callback that will never happens as the PageRequestManager did not start it. Additionally, in F12 Network tab, I can see that there is no request performed for the callback to request the items of the combo-box.

I reproduce the issue with the following steps:
1- Have a page with a RadComboBox, a ScriptManager with partial rendering enabled and an UpdatePanel.
2- In the browser, trigger the async postback to refresh the UpdatePanel
3- From JavaScript, while the async postback is in progress, call the requestItems method of the RadComboBox
4- Open the drop-down of the combo, and you can see the "Loading" text at the top, with the initial list of items. And it stays like this until another call is made to requestItems when there is no async post-back in progress which will actually perform the callback.

RadClientDataSource does not update the data properly when bound to EntityDataSource. The proper data is displayed only of first load (when the data is fetched via _kendoDataSource.read()), but not after an update (e.g. a page change)

Steps to reproduce:

  1. Open https://demos.telerik.com/aspnet-ajax/clientdatasource/functionality/binding-to-datasourcecontrols/defaultcs.aspx
  2. Do either one of the following
     - Change to page 2 and go back to page 1
     - Hitting refresh loses all data
     - Edit multiple values before saving -> many of them are lost
     - Upon save, the old data reappears before being updated.

Result - the Grid is not bound with the correct data

There is a black line that has appeared in my RadMenu.

The problem can be solved by adding a display: none in the following class:

.RadMenu .rmGroup:before, .RadMenu .rmMultiColumn:before, .RadMenu .rmScrollWrap>.rmHorizontal:before, .RadMenu .rmScrollWrap>.rmVertical:before

Native browser behavior is vendor specific and the above issue cannot be replicated with the latest version. Default browser in latest Android versions is Chrome and we recommend using it instead of the older native browser
