Linq to sql RadGrid Paging Speed

I have a database with simple table with 1.2 million rows and when I put that into a grid using linq, paging is painfully slow. In the demo http://demos.telerik.com/aspnet-ajax/Grid/Examples/GeneralFeatures/ASPNET35/DefaultCS.aspx it looks like the source code isn't all there, am i missing something? When I put in the .cs file code that is listed in the demo I get no results when paging or sorting, something is missing.

RadWindow moves to the top upon close

I open a modal rad window as popup and while opening through javascript, i use to MoveTo api to move to it to the centre of the screen. On the window, I have a button called close, which on click, executes close() on the window, but to my surprise, when the window is closed, the other window that opened it, scrolls to the top..
when i looked in detail, the radwindow had some default close event handler, which uses some "_focusedPageElement" and focuses on it,, in my case _focusedPageElement was referring to the iframe of the window that opened the popup..
why is that?? how can i prevent that?

How to implement serialization of fields of the Form containing RadEditor

How to implement serialization of fields of the Form, that contains RadEditor (in order to make callback-request)? Microsoft JavaScript function WebForm_InitCallback() does it, scanning form fields and adding their values in a variable __theFormPostData. But in a case with RadEditor, it finds only <textarea> (<textarea ... id="RadEditor1ContentHiddenTextarea" style="display: none;">), that contains the initial data (loaded with page). How (before i make callback-request) it is possible to update value in <textarea> on the data from <iframe>? And what is purpose of <textarea> element?

Known Issues and Breaking Changes

Q2 2011 Service Pack 1 (Version 2011.2.915)

Breaking change: Now all HTML 5 compliant browsers, which support the File API interface (FireFox 4.0+, Chrome latest, Safari 5.0+), use the File API module.

Reason: Numerous of problems with the Silverlight/Flash plugins in browsers different than IE. The FileAPI module provides the same features as Flash/Silverlight with one exception. It is not yet possible to display extensions filter within the select file dialog. However, this functionality is part of the input[type='file'] specification and it is about time that the browsers implement it.

Problem: Using the Flash module in IE6/7/8 debug information is displayed into the Developers Bar JavaScript console.

Reason: Non commented console.log invocation within the ActionScript code.

Solution: The problem will be resolved in the upcoming Latest internal build.

Q2 2010 (Version 2011.2.713)

Problem: RadAsyncUpload sometimes fail to upload the files to the target folder.

Reason: The temporary files, which RadAsyncUpload uses internally to save the uploaded files to the target folder, are being deleted too early, hence leaving the upload without files to save.

Solution: We have fixed the problem for the latest internal build (version 2010.2.722+). More information on how to obtain the latest internal build can be found here.

Alternatively, you can do the following:

Step 1: Add an ashx handler to your app. Inside, use the following code:

<%@ WebHandler Language="C#" Class="CustomHandler" %>

using System;

using System.Web;

using Telerik.Web.UI;

public class CustomHandler : AsyncUploadHandler {

protected override IAsyncUploadResult Process(UploadedFile file, HttpContext context, IAsyncUploadConfiguration configuration, string tempFileName)

{

configuration.TimeToLive = TimeSpan.FromHours(4);

return base.Process(file, context, configuration, tempFileName);

}

Then, set the HttpHandlerUrl property of RadAsyncUpload to point to that handler. Like this:

<telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" HttpHandlerUrl="~/CustomHandler.ashx" TargetFolder="~/Documents">

</telerik:RadAsyncUpload>

Other issues:

SOLUTION: Upload fails OR Login prompt appears when using Forms / Windows Authentication

Rad Editor Lite Does Not Pass SPDisposeCheck

We are using RadEditor LIte on SharePoint/MOSS 2007. When checking for memory leaks with SPDisposeCheck, RadEditor is listed as not disposing of all its memory. Is this a false positive? We are on version 4.5.3.0 but checked the dll for the newer version, and it still does not pass the SPDisposeCheck.

Thanks, Connie
