Issue: Export to Excel Functionality developed using Telerik Grid doesnt work in IE 11 browser.

In one my applications the Export to excel Functionality is not working in IE 11. When the export to Excel Functionality is button is clicked , it gives a blank excel workbook without any data in IE 11 browser where as this works fine in IE 8 browser. I have attached the document with screenshots.

Code snippets:

  //Start- script to enable controls after export to excel
    if (typeof (_spBodyOnLoadFunctionNames) != 'undefined' && _spBodyOnLoadFunctionNames != null) {
        _spBodyOnLoadFunctionNames.push("supressSubmitWraper");
    }
    function supressSubmitWraper() {
        _spSuppressFormOnSubmitWrapper = true;
    }
    //End- script to enable controls after export to excel

    function click_handlerConsumptionReport() {
        theForm.__EVENTTARGET.value = '__Page';
        theForm.__EVENTARGUMENT.value = 'Export';
        theForm.submit();
        theForm.__EVENTARGUMENT.value = '';
    }

The text in the tabs' titles of the Sliding panes of the Splitter control are not properly rotated.

The styles related to multipage are too broad and affect all child iframes, not just the one from multipage.

The second iframe must not inherit any styles

<telerik:RadMultiPage runat="server" SelectedIndex="1">
    <telerik:RadPageView runat="server" ContentUrl="http://www.telerik.com" >
    </telerik:RadPageView>
    <telerik:RadPageView runat="server">
        <div>
            <iframe src="http://www.telerik.com" ></iframe>
        </div>
    </telerik:RadPageView>
</telerik:RadMultiPage>

The best approach is to handle the OnClientTileClicking event for the TileList and determine whether it should be cancelled: http://www.telerik.com/help/aspnet-ajax/tilelist-client-side-events-onclienttileclicking.html.

A possible way to change the behavior is to pass the _cancel field value from the Clicking event of the Tile to the TileClicking event of the TileList with the following override.

			var $T = Telerik.Web.UI;
			$T.RadTileList.prototype._onTileClicking = function (tile, args)
			{
				var eventArgs = new $T.RadTileListCancelEventArgs(tile, args.get_value());
				eventArgs.set_cancel(args.get_cancel()); //the change - pass the _cancel argument to the TileList handler too
				this.raiseEvent("tileClicking", eventArgs);
				args.set_cancel(tile._isDragged || eventArgs.get_cancel());
				args.set_value(eventArgs.get_value());
				tile._isDragged = false;
			}

Brief Description of Issue: If you try to put HTML comments into the HTML view of an HTML module using the default rich text editor you will find that the comments are visible when you save the content.

Clear Steps to Reproduce:
Install DotNetNuke 7.0.2
Login with admin/host
Edit an HTML module
Switch to the HTML view of the editor
put <!--Test-->
Save
View the page and you will see <!--Test-->
Expected Result:
The comment should be just that, a COMMENT, not visible to the browser unless you were viewing the source of the page.
