RadDock Problem with RadWindow

Dear,

I'm trying to create nested raddockzones in a page, and load that page within RadWindow.
but my problem is the nested raddockzones is inactive in IE9 and IE8 browsers, but work on other browsers.
FYI, this works if you add the nested raddockzones in RadWindow ContentTemplate directly, but I want to load external page from RadWindow.

please help me with this problem, urgent.

Thanks.

Skinning user controls via radskinmanager

I am creating 2 web server controls for our project using telerik asp.net ajax controls. Controls are derived from ISkinnableControl interface.

I have created skin by modifying exisiting skin file css classes to build our skin. I want to use custom prefixes for css (i,e myCalendar). Reason is that same telerik control is used in both user controls.If I use telerik style class prefixes there could be clash in style.

.myCalendar_<skinname> .rcTitlebar table

{

table-layout: auto

width: 100%

border-collapse: separate

border: 0

border-style: none

;

}

//code to set css to control (inside userconctrol.cs)

protected override void

CreateChildControls()

        {

base

.CreateChildControls(); 

        _calendar =

new

RadCalendar();

        _calendar.EnableEmbeddedSkins =

false

;

	_calendar.EnableEmbeddedBaseStylesheet =

false

;

        _calendar.CssClass =

"myCalendar myCalendar_"

+ Skin;

        _calendar.Skin = Skin;

	...

}

On Aspx page I have RadSkinManager to apply skin to control instances.
To Apply skin, Currently I have 2 options. I have to do it for each control instance.
1. Set it in markup at design time
2. Set it via page_preinit event.

How can I achieve following
Use custom preffixes in css stylesheets. When RadSkinManager skin changes, it should automatically apply it to control instances. I don't want user to register control instances in radSkinmanager targetControls collection / assign skin it to indivisual control instances.

Note: I am storing css files in library assembly and using stylesheetmanager to load them in application.

My problem is similar to
http://www.telerik.com/community/forums/aspnet-ajax/skin-manager/generic-code-to-apply-skin-to-all-user-controls-on-page.aspx

Thanks & Regards

Site Map child level not displaying

My Site Map is not displaying the child level in Sitefinity | Pages | Site Map | . The menu system in the 'live site' is working fine; again, it is just in the admin backend that it is not expanding - and just in the actual Pages | Site Map - the menu displays correctly in the "Edit this page" view.
Our servers went down last week, so I believe it is a server related issue. I believe we are on Sitefinity ver 3.7. We have a number of different sites running Sitefinity and am very happy with it - but at this time, they all have the same error. With the Child levels not displaying, there is no way to get at the pages to edit them. [attached image]

Using RadInputManager To Compare Two TextBox Controls

Does anyone know if it's possible to use the RadInputManager to compare two TextBox controls the way a CompareValidator control does? I like having the warning icons in my TextBox controls and when I use the CompareValidator control, I don't get them when two TextBox's text properties are different.

I've also found the reason of this issue its because of the query string of the page on which this grid is implemented. When grid item is rendered on form then every link item is taking same query string as of page's query string. This issue is not getting occurred when I run above code without using query string.

Please help me...
