Hello,

In my project, I open up a RadWindow that has 3 combo boxes, amoung other controls. The comboboxes are: RadComboBoxGrupos, RadComboBoxProjectos and RadComboBoxUser (TemplateItems with checkbox and label). The last two should be dependent on the first. When I want to postback, I can get the single selected values on the RadComboBoxGrupos and RadComboBoxProjectos comboboxes but I want to get all items in the templateItem box (RadComboBoxUser) and cycle through all of them see which ones have a checked checkbox. But I can't get the items, only if I specify a single selected item.

Any ideas on how to do this?

Here is my code:

Window aspx:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="CreateCoordTaskForm.aspx.cs" Inherits="CreateTaskForm" %> 
 
<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>
