CheckedNodes.Count returns 0 when TreeView on Master Page

I moved my implementation to use Master Pages now the CheckedNodes.Count is always 0.The code is below.

RadTreeView RadTreeView1 = (RadTreeView)Master.FindControl ("RadTreeView1");

checkedCategories = RadTreeView1.CheckedNodes.Count;

It worked fine when it was on the same page. I don't have RadFormDecorator.

Custom loading panel is only displayed correctly first time window is loaded

Hello. I have followed the instructions in this article in order to display a custom loading panel when opening a RadWindow:

http://www.telerik.com/support/kb/aspnet-ajax/window/custom-loading-sign-for-radwindow.aspx

This worked great for me - thanks for putting it together. I am noticing, however, that the custom loading panel only displays correctly the first time the window is loaded - every time after that, the loading panel is not displayed correctly, even when ReloadOnShow=true for the window. When the entire page is reloaded, the loading panel displays correctly, but again, only on the first show.

I have modified the sample project from the above link to demontrate the problem and included both code and images displaying the behavior.

Default.aspx - Defines a window with ReloadOnShow=true that uses a custom loading panel

Change Grid Column Header Font Color

I have a grid that has databound columns that are defined in the aspx code. When preparing the data for NeedDataSource(), more columns will be dynamically added to the right side of the grid. This all works great. My problem is that some of these dynamically added columns will need the color of the font of the LinkButton (for sorting) in the header to turn gray once databound. Which header column needs to change will be tracked on the server side. So my question is: Where is the best place on the server side (which event) to change the font color for the header column and how?

I've tried setting the .ForeColor property to gray & setting the .CssClass property in the ItemCreated, ItemDatabound, & PreRender events to no avail. I do have a custom skin on my grid.

Web.config registration missing!

Hello,

I am using asp.net ajax radeditor 2009.3.1314.35. I have tried the solution from "Error: Web.config registration missing! The Telerik dialogs require a HttpHandler registration in the web.config file." but no help. Actually on my localhost the solution works but on the server it always gives me this error and throws the dialog window to the login page.

---------------------------
Message from webpage
---------------------------
Web.config registration missing!
The Telerik dialogs require a HttpHandler registration in the web.config file. Please, use the control's Smart Tag to add the handler automatically, or see the help for more information: Controls > RadEditor > Dialogs > Introduction
---------------------------
OK

Any idea whats wrong ?

Rating Column Rendering Error

Hi,

I have a rating column inside a ragrid, which usually works fine, however I am encountering an error when I add new items to it for the first time.

If items are loaded from the database, then they appear correctly, however if I update the previously empty data source with a new item, the rating column will display hyperlinks for 1,2,3,4,5, rather than the star images that are usually present. Please see the attached screenshots for more details.

I haven't come across this problem anywhere else on the forum, so any help would be appreciated.
