Hello Telerik Team,

I've an user control which has a AJAX Panel. This user control is loaded in a Page which has a AJAX Manager. I want to raise the Ajax_Request of the consuming page from withing the user control on certain condition.
I tried to use  This causes a error in MicrosoftAjax.debug.js Assembly:    System.Web.Extensions Version:     3.5.0.0 FileVersion: 3.5.30729.196

Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null 

for Controls and Behaviors.Parameter name: element

How do I achieve the desired effect.

Regards

Alok

Hi, I just wondered if someone might be able to help me.

I have a radtooltip which is generated from a webservice for speed, and within this tooltip I have a radcalendar.  As you would expect none of the ajax events for the calendar work anymore.  Is there any way around this, or is it unfixable?

Cheers,

Davoc

Hey Guys,

I have the following problem:

I use the RadGrid in a SharePoint webpart. Everythink is ok but, when I use the group feature in relation with static headers, there is a layout issue with the GroupHeader.
The text of the groupheader is aligned to the top so that the first groupheader overlaps with radgrid headers and the next groupheader overlaps with the groupheader before.
To solve the problem I tried to set the VerticalAlign.(radGrid.GroupHeaderItemStyle.VerticalAlign = VerticalAlign.Middle;)
The crazy think no is, that when the RadGrid gets the focus, the groupheaders will be align correct. But after grouping they will be align wrong again.
I found a thread in in the forum which describes similar problems but this could not solve the problem.
The images in the attachements shows the problem.

Please Help!

I've tried every solution provided on the forums and online and I'm still receiving the "Telerik is undefined" error when referencing

Telerik.Web.UI.RadListBoxItem in javascript code.  I'm using version 2010.2.826.35.   Here's what I've tried so far....

1.
<location path="Telerik.Web.UI.WebResource.axd">
    <system.web>
        <authorization>
            <allow users="*"/>
        </authorization>
    </system.web>
</location>

2. in <system.webServer>, <handlers>...
 
<add name="Telerik.Web.UI.WebResource.axd_" path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" preCondition="integratedMode,runtimeVersionv2.0" />

I'm at a lost right now.  I'm just trying to insert some rows in a RadListBox via javascript.   Any help is appreciated.

Thanks.

Hi,
    Am using Rad Chart Control.
1) I can add one legend in single chart. Is this possible to add more than one legend in a single chart?
2) In Line series, based on condition for particular X-Y value, i want to show the image/icon in X-Axis for y-value. Is this possible?

Thanks.

hi,
I have a RadTreeView as a page node list on a master page.When you click node in the treeview, a page will be showed in the right side of the master page. In the right side, I put an iframe, and the page will be shown in the iframe. I use client side event:OnClientNodeClicked for the RadTreeView. In the client event, it will set the src of the iframe:
myIfrmame.src = linkURL;

Now the question: 
When user click a node, I want to display a RadAjaxLoading Panel first before the render of the page completed. How to achieve that? Anyone who have any suggestion, will be greatly appreciated.

Is there a limit on how many times an appointment can recur? I created an appointment with the following properties:

Start date: 1/9/2003 12:00:00 AM
End date: 1/15/2003 12:00:00 AM

Recurrence rule:
DTSTART:20030109T000000Z
DTEND:20030115T000000Z
RRULE:FREQ=WEEKLY;UNTIL=20981231T000000Z;INTERVAL=1;BYDAY=TH

And sure, it recurs. But only until 3/24/2011. The last entry I get is one showing up from 3/24/2011 through 3/29/2011, and then, no more. Notice how the Recurrencerule says UNTIL=20981231? So how come it stops in 2011?

Naturally, if we move the schedule back one year, i.e.

Start date: 1/9/2003 12:00:00 AM
End date: 1/15/2003 12:00:00 AM

Recurrence rule:
DTSTART:20020109T000000Z
DTEND:20020115T000000Z
RRULE:FREQ=WEEKLY;UNTIL=20981231T000000Z;INTERVAL=1;BYDAY=WE

The last entry I can see is now 3/18/2010 through 3/23/2010.

As far as I know, this behavior isn't documented anywhere. Is this a bug?
