RadAjaxManager and Usercontrol does not work

I have a UserControl that implements IPostBackEventHandler and I have several problems:

void IPostBackEventHandler.RaisePostBackEvent(string eventArgument)

{

if (eventArgument.Equals("Refresh", StringComparison.InvariantCultureIgnoreCase))

Refresh();

}

1) RadAjaxManager Property Builder does not list my control. I must add it manually in the Page_Load event.
2) When I initiate an ajax postback in javascript with the following code it does a normal postback (not ajax postback):

<%= Page.GetPostBackEventReference(FormView.FindControl("anotaciones"), "Refresh"

) %>

I solved the problem with two "not elegant" solutions:

1) By ajaxfing the whole FormView (totally inefficient!)
2) Or by putting the usercontrol in a RadAjaxPanel and then implementing the Ajax_Request event:

((sender as Control).FindControl("anotaciones") as Anotaciones).Refresh();

Is this a common practice? Or should RadAjaxManager work?
Thanks a lot!

Installation of Telerik Controls 2009 Q3

I have Telerik Premium Collection for .NET 2009 Q3. The subscription is expired on Jan 16, 2009.

Currently I am using the VS 2005 professional version on a Windows 7 Home Premium 64 bit PC. I am planning to upgrade the VS to VS2010 Professional.

However, I need to keep both version vs2005 and vs2010 at the same time.

May I know:
1. What is the best practice to install the Telerik controls? I already install the Telerik controls for VS 2005.
2. Is it possible to run Dot Net FW 4.0 for VS 2010 and Dot Net FW 2.0 for VS 2005 at the same time?

Thanks.

Fieldset padding difference in IE8 vs Firefox & Crome

Hi!

When using FormDecorator on Fieldset the page render with different paddings for IE8 compared to Firefox and Crome.
Use this link: http://demos.telerik.com/aspnet-ajax/formdecorator/examples/default/defaultcs.aspx to see the difference att the top, "Decoration Zone".
Is there a fix for this? If I hit the compatibly button in IE8 it renders almost the same as in Firefox and Crome.

Sincerely, Thomas

Get value of sibling combobox on client side in ClientItemsRequesting handler?

I have a RadGrid with two GridTemplateColumn columns, each of which contains a RadcomboBox within the EditItemTemplate.

I am trying to configure page method-based auto-complete for each combobox. The first will contain two items (say, "Colors" and "Numbers") and the second will ask a page method for a list of items that are relevant for what was selected in the first combobox; e.g., if the user selects "Colors" from the first combobox, he may only select a color from the second combobox. Likewise, if he instead selects "Numbers" from the first list, he can only select numbers from the second list. The page method used by the second combobox takes a parameter which is the value of the selection from the first combobox.

For the second combobox, I am attempting to use the ClientItemsRequesting event handler to set the value of the parameter to the page method a la http://trappedinhoth.blogspot.com/2008/05/telerik-radcombobox-auto-complete.html.

The ClientItemsRequesting event handler gives me the sender, which is the second combobox. From that, how do I get the value of the first combobox?

Thanks
