When the form element is offset, RadAutoCompleteBox popup is not properly positioned unlike the Combo / Dropdown counterparts.

Since we append all popups in the FORM element, the issue is only exhibited if FORM is not top level element, but is instead nested. The most obvious case is when you have Bootstrap structured page: .container > .row > .column.offset-3 > *form* > radautocompletebox.

Using the web.config to enable lightweight or auto rendering for all controls, some of RadEditor dialogs (most of them are the Lite Dialogs) have visual issues and are impossible to be used. 

The editor does not go to edit mode. The problem occurs also when Auto mode is used. This prevents the developers to rely on the AutoResizeHeight functionality when a mix of all rendering modes is required. 

Possible workaround is to use the RadDeviceDetectionFramework - http://docs.telerik.com/devtools/aspnet-ajax/controls/raddevicedetectionframework - and programmatically disable the AutoResizeHeight in mobile devices:

ASP.NET
<telerik:RadEditor ID="RadEditor1" runat="server" RenderMode="Auto"
    AutoResizeHeight="true">
    <Content>
        <p>editor</p>
    </Content>
</telerik:RadEditor>

C#
using Telerik.Web.Device.Detection;

public partial class Default : System.Web.UI.Page
{
    private void Page_Load()
    {
        if (Detector.GetScreenSize(Request.UserAgent) < DeviceScreenSize.Medium) {
            RadEditor1.AutoResizeHeight = false;
        }
    }
}

It would be helpful , if you provide image library like Visual Studio provides.
The image library can have all the standard and specific icons of telerik.

Using this method to programmatically select the content area does not work as expected in Edge browser.

Possible workaround is to use ContentAreaMode="Div". Or using editor.get_contentArea().focus() method instead of editor.setFocus() (This might not work for some legacy browsers).

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 = '';
    }
