Hello,

I have a page having a couple of grids

Everything seems working fine, once it is deployed in the server the grids in a specific page is taking life to load if there is no record!

When there is no record, we bind the grid with an object having null reference

Any workarounds?

Thank you

Regards
Raj

[Solved] Drag and Drop Cell

I'm working with the Item Drag and Drop sample, and it works very well. However, I have modified it slightly. The source datagrid has a different number of columns than the destination datagrid. I have modified the code so that when the item is dropped, I manually add the row to the grid. That all works fine, but I really would like to know which column the item was dropped on. Is there a way to get this information?

Thanks,
Derrick.

Wierd RadEditor rendering - shows no editor but alot of bullets

Hello,

Im experiencing a wierd rendering issue with RadEditor and i really need to fix the problem, as it is driving the customer crazy. Take a look at the attached screenshots. Sometimes when I enter the page where the editor is used, the editor is not displayed at all, only a wierd list of bullets (error.jpg). I have been unable to see any pattern as to when the problem occurs, but sometimes I wont see it for days and at other times it will occur 2-3 times a day.

Do you guys have any idea of what could be the problem?

Memory leak in very simple application using ASP.NET Ajax RAD controls.

We tested RadControls_for_ASP.NET_AJAX_2010_1_519_dev with very simple appliocation and found out that IE8 has memory lteaks issue.
The application is just simple RadGridView that is being updating every 5 seconds with the same data. We used RadAjaxManager for the grid.
We need in future to deploy more complicated apps that, loaded to IE8 client page will work for days in the same Session without refresh.

What do we have to do to avoid this problem?

Thank You.

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.
