Error when RadGrid right arrow is pressed in edit mode and keyboard navigation is enabled

Hi, need help with this error. By reading the fixed issues on past releases i found this one: Fixed: Error when RadGrid left arrow is pressed in edit mode and keyboard navigation is enabled.

I'm using the Q2 2011 SP1 Release, and yes it is fixed, but the error came out when pressing the right arrow.

I dont know if this is a tracked issue, but i need a way to avoid the error in my website using this release.

I have an option to make it? Maybe disabling the left and right arrows?

Thanks for your help

Telerik Web Ui without internet connection?

Hi,
I am working on a intranet solution for our customers using Telerik Ajax toolkit.

During some debugging I figured out that the pages did a couple of requests to http://aspnet-scripts.telerikstatic.com/ajaxz... where it loads javascript files from.
I was shocked seeing outgoing connections, since the project is meant to work in a local LAN without internet access.
Disconnecting my network cable and reloading the page lead to a nonworking page.
My customers will use the web application in a sealed productivity environment where an internet connection will not be accepted nor possible in the most cases.

Requesting external script files from the internet turned telerik tools from brilliant to useless for the whole project.

Please tell me there is a way to circumvent these requests, and use local web resources instead.

Kind Regards
Timo

HtmlChart ActiveRegions and image maps?

Hi - I've been trying to convert my application from using RadCharts to using the much nicer looking RadHtmlCharts (Q2 2012 v2012.2.607.35), but have got stuck at implementing the equivalent of the RadChart's ActiveRegions (http://www.telerik.com/help/aspnet-ajax/chart-image-maps.html).

Does anyone know if the RadHtmlChart supports any form of active elements with click through to a custom url?

Thanks in advance
Tom

Migrating from UpdatePanel to RadAjaxPanel

I have a server control which shows/hides a few radcombobox controls based on previous selections (within the same control). These controls are placed inside an UpdatePanel (panel created OnInit, controls added OnLoad) to minimize full page refreshes and this all works great.

We're consolidating on RadAjax and I figured it would be a simple migration to RadAjaxPanel but when I switch in the RadAjaxPanel I'm getting full page refreshes, not just on the first select (as described in other threads) but on all control interactions.

I have set EnableAJAX to true and I have also hooked the AjaxSettingCreating event to get the default behaviour of UpdatePanel (i.e. UpdateMode = always and ChildrenAsTriggers = true).

Are there some other settings I need to make to get parity with the UpdatePanel?

Many Thanks,

Brian

OnClientClicked event in code behind

Hi,

I have a simple button that I create at runtime.

Dim btn as New RadButton()

btn.AutoPostBack = False

btn.OnClientClicked = "BtnClicked"

function BtnClicked(sender, args)

{

alert("Hey!");

}

When I click on the button, BtnClick is not fired. What is wrong my code?

Thanks.

RadAjaxManager loading/displaying controls in reverse order

I am upgrading 2008 Q3 version of telerik control to 2011 Q3 version in my project in .NET 4.0. I have a RadAjaxManager used in the page that has a updated control as asp:panel. Multiple user controls are dynamically loaded in to the asp:panel. Initally all the instance of the user control displays the loading image before displaying the content. Before with 2008 version, it dislays all the user controls in top down order. but with the 2011 version it displays in bottom up which is really strange. I appreciate any suggestion on fixing this order issue. Thanks in advance!

RadAjaxLoadingPanel with MasterPage?

Within my master page I have a RadSplitter layout. One of the Splitter panes contains the MasterPage contentholder and since the requirement called for only this area to update on the click of a navigation node item I placed an iframe within the contentholder (All content in iframe is located within the site itself). I was wondering however, if there is a way to utilize and show the RadAjaxLoadingPanel after the navigation node item has been clicked and hides when the page in the iframe is finished loading?
