[David]

Hi,

Just hoping this is possble, i have a List of Objects that i want to bind in a ComboBox (Not a problem) but then that list also has a list of Object's which i would like to display and selectable. I.E.

like this
Object 1
=========
    Object1a
    Object1b
    Object1c
Object 2
=========   
    Object 2a
    Object 2b

ETC...

Hope someone has done this in the past

Thanks David

Hello David,

I hope the following link will be of help:

I should note that the source code is using older version of the RadComboBox Template, so you will have to update the XAML manually with the version you use. Let me know if you have problems with this.

Is there a quick way to get the template?

or is it just create a dummy project goto blend and then edit template copy etc....

Hello David,

The quickest way is to open blend, create dummy project, put references to Telerik.Windows.Controls.dll and Telerik.Windows.Controls.Input.dll, add a RadComboBox, select edit control template from the context menu and you will get what you need.

Right i have got the point of AddHandler which doesn't seem to be there?

Any clues?

David

[Valeri Hristov]

AddHandler is an extension method defined in the Telerik.Windows namespace. You need to add "using Telerik.Windows;" in your code.

Hello David,

I just updated the source code of the blog post with the new RadComboBox styles. For your convenience I am attaching the application here - note that you should use the assemblies from Q1 2009 SP1, which was released last week. Please, let me know if you still experience problems using it.
