Hi I have read this thread http://www.telerik.com/help/aspnet-ajax/schedule_appearancetemplates.html on using templates I would like to be able to use the radio buttons to assign the job to a dept

when I load the page I get the following error

Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

this is my aspx

Hi mike,

The templates should we within RadScheduler. I realize that the help topic you have referred to shows only the templates code and not the entire context of RadScheduler so this might have confused you. Here is an online demo that better illustrates how to use and define templates:

Hi Mike,

All the code (aspx, code-behind, etc.) can be viewed from the code tabs. Please, see the attached screenshot. The RadScheduler instance is defined in the aspx code and it is bound to a sample data source. Let me know if you have further questions.

All the best,
Peter
