Gridview does not load items properly with Ajax Manager

Hi, I am trying to use RadAjaxManager to cause my gridview to add items when a button is clicked. These items are stored in a session variable. When I use the RadUpdatePanel, everything works as expected, except the whole page reloads and is slow. I would like to show a loading panel over each contorl that is loading (my actual page is quite complex). When I click the button to add an item to the radgrid, it shows the loading panel, but the grid does not show any new items. However if I click other things on the page, the items that were added will appear. I've been searching for quite some time for a solution to my problem. Also note:I'm trying NOT to use javascript if possible. My setup is as follows:

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"

CodeBehind="Default.aspx.cs" Inherits="WebApplication5._Default" %>

<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

Export to Excel using Windows7

"Cell Limit Error". We have code that has been executing successfully for some time to export data to an excel spreadsheet with RadGrid. This code is executing successfully on our older operating systems. However, on machines that have Windows 7 installed we are having a problem. All data is being dumped into a single row and column creating error , "cell limit". Why should this be occurring? Is this related to our version of skins? It looks like we are using "default".
Do we need to change Radcontrols for Windows 7.

spell checker and firefox

I notice that firefox has its own spell checker. I also notice that when right clicking in the editor in Firefox, you get the standard Firefox context menu as opposed to the Teleirk one (with Paste, Paste from Word, etc.).

Since I allow users to add custom dictionary items and use a central custom dictionary, I would prefer to only use the Teleirk Rad Spell Checker. Is there any way to prevent the firefox spell checker from being used?

Also, is there any way to get the telerik context menu to show up in firefox?

RadDatePicker and timezones

I have a RadDatePicker control. I select a date and submit the form. In the code behind, the datetime object is a date in UTC, that is not the same as the entered date. This is because the calendar uses internally a javascript Date object, which picks the locale of the client's browser and client-locale to UTC conversion seems to happen on the server. Is there a way to get the exact date that has been entered, regardless of the client settings of the user and the browser? I want the dates that my input receives to be treated just as entered without any timezone information or conversions. I want to use that date as UTC date in my logic, but since it is being converted automatically, I happen to operate with wrong data.

RadGrid client side toggle selection with server side persisting of the selected items after Sorting, Filtering and Paging

My problem is related to this Code Library solution for Row Selection Persistence on Paging & Filtering.

The header checkbox does not work if Grouping is enabled in the RadGrid and/or there is another RadGrid nested within in the outer RadGrid.

I've added the Group Expressions and NestedViewTemplate in the code sample to reproduce the problem. Could anyone please mention the reason why the header selection does not work in this code sample with Grouping and NestedViewTemplate ?

<telerik:RadGrid ID="RadGrid1" runat="server" Skin="Outlook" AllowSorting="true" AllowPaging="true"

RadControls for ASP.NET AJAX Trial

Hi,

I'm currently using the trial version of the controls.

Does the trial version expire and, if so, can the trial be extended?

Thanks.

Repeater with Web user control

Hello,

I'm have a similar setup to this demo: http://demos.telerik.com/aspnet-ajax/tooltip/examples/default/defaultcs.aspx.
Where I have a repeater, radtooltipmanager that loads a Web User Control that contains a RadUpload and a submit button.
The key difference between the demo and my is that I have a RadUpload control on the Web User Control.
I can't get the RadUpload to work. I understand that I have to disable AJAX somehow,
but can't seem to get to work properly.

Please advise.

Thanks,
Quan
