I have clickable nodes in my treeview. I am adding a custom class to them, but I cannot get this to show up. I have tried a wide variety of settings in CSS. The class I am adding is called rednode. Here is what the node looks like in the page source:

<span class="rtSp"></span><input type="checkbox" class="rtChk" /><img src="images/page_white_text.png" alt="" class="rtImg" /><a class="rtIn rednode" href="javascript:setValue('10003')">Great Deals</a>

</div></li>

Could you please tell me what to do in my style sheet so that this node is colored red?? The sample on your site does not use a linked node.

Best way to detect page is in a radWindow

I'm looking for a javascript logic that I can use to detect if the page is in a RadWindow or not. The main reason is that I need to call the radWindow.close() when inside a RadWindow or self.close() when in just a regular browser window. How best to handle this?

Also, keep in mind that the parent page that launched the window may not have any Telerik content. We have an application that has two modes: Normal (with Telerik Controls) and 508 (which does not have any Telerik controls).

RadListBox behaving strangely embedded in server control

Hi,

I like the functionality provided by a pair of listboxes set up as a source and target. What I don't like is to have to declare them separately, databind and ultimately looping through the items in the target listbox to get a list of selected values. I have therefore tried to wrap all of this in a server control. The constructor takes a name, an IEnumerable list as datasource and the names of the text and value properties. It also provides a "GetSelectedItems()" method that returns the selected values as a CSV string (which is what I need). When I instantiate this server control it looks and appears to function as expected.

Now to the problem: when the page posts back the target listbox is empty. The items added clientside disappears. Clearly, this is not supposed to happen, so I must have done something wrong. I enclose the code for my server control below. Any pointers will be greatly appreciated.

Sincerely,
Lasse

An Unhandled Exception Has Occurred.Could not load file or assembly 'Telerik.Web.UI, Version = 2009.3.1103.35...Or One of its dependencies. The System Cannot find the file specified

Hi,
This is my first post. I saw a similar post but it didnt really solve my issues. I actually uninstalled and re-installed VB2008 and all the controls in my project started showing me this error: Error Rendering control. An Unhandled Exception Has Occurred.Could not load file or assembly 'Telerik.Web.UI, Version = 2009.3.1103.35...Or One of its dependencies. The System Cannot find the file specified.

I will be very grateful if someone can suggest a solution quickly.

Regards,

Charles

Hi all-
Downloaded the free trial verison of the Telerik ASp.NET AJAX controls. I was looking at Menu and wanted to build a navigation menu similar to what we see on home page for Telerik when you click PRODUCTS.
