RadFileExplorer very slow

Hello,

This new FileExplorer control is very, very, very slow to open folders with a lot of files in Internet Explorer 7. Testing with a folder with 1000 jpg files, 4Kb each file, take more than 5 minutes to open in a machine with Dual Xeon processor and SAS 15K speed disk and causes iexplorer process to consume much cpu.

With Firefox works very fast.

Regards,
Newton

RadEditor Dialogs not working

I'm currently attempting to use the RadEditor in a mixed project that contains routing for MVC, WebAPI, and Friendly URLs.  I'm getting errors when I attempt to open the ImageManager dialog box from within the Editor.  I suspect this has something to do with the routing rules, but all my attempts to exclude the dialogs has failed so far.  

The dialogs are registered in web.config (both, system.webserver and system.web).

Does anyone have the specifics on what to add to the routing config?  Or if you've encountered this, and it isn't the routing, please shed some light!

Thank you in advance,

Alex

Display content on right side when clicked on left side navigation menus

I would like to split a page into two columns with RadPageLayout. Left side will display all the navigation menus (links) and the right side should display the content when one of the links is clicked. I don't want to do any postback rather do some ajax may be Radajaxmanager. What specific controls should i use. Is it possible to reference the contents being displayed to some page (eg: contacts.aspx)

Slow closing RadWindow Lightweight rendering in Internet Explorer

Guys, 

I am facing a performance issue when closing a radwindow Lightweight rendering in only IE browser (IE v11).

I tried hiding the radwindow by using onClientBeforeClose client event to improve user experience BUT I got no lucky. The problem is still the same.

Is there any way which can solve it or improve UX when closing the radwindow?

function OnClientBeforeCloseHandler(sender, args) {
    if (sender && sender.get_popupElement() && sender.get_popupElement().style && $telerik.isIE) {
        sender.get_popupElement().style.display = "none";
    }
}

[Solved] RadAutoCompleteBox filter callback misses letters that are entered after it sends the callback for first letter.

RadAutoCompleteBox comes back with the wrong filtered result set when typing into the textbox. It seems to be doing the filtering on the first letter I'm typing, but then ignoring the second letter I've typed. For example, if I start to type the word "test" it will start filtering the auto complete box for "t" or "te", but ignore the rest of the word. It seems to be doing the filtering if i very briefly pause (split second) and that's why it's not picking up the whole word. If I hit backspace, then it does a callback and the filtered result set is accurate. Is there a built in way to delay the filtering so it only does the callback after I've stopped typing for one second? Thanks in advance for the help.

 

Here's the code:

<telerik:radautocompletebox id="txtSearch" runat="server" oncliententryadding="OnClientEntryAddingHandler" emptymessage="FIND AN ACCOUNT or TPID"
                                    autopostback="true" onentryadded="autocomplete_EntryAdded" filter="Contains" datavaluefield="TPID" datatextfield="AccountName" 
                                    cssclass="searchtext" width="275px" DropDownAutoWidth="Enabled" maxresultcount="10">
                            </telerik:radautocompletebox>
