>Hi Sascha,
Thank you for your interest in Syncfusion Products.
The CallbackPanel and the CallbackMultiplexer is to be deprecated in the future releases. So we have marked these controls as Toolboxitem(false). You can use these controls by registering it in the aspx page with tag prefixes or you can use the UpdatePanel class instead, which enables the sections of the page to be partially rendered without a postback. Please refer the below link to get more details on this issue:

Thanks,

Hi Melba,
thanks for your reply. That's not exactly what I wanted to hear (read) as I rely on your controls more than to those of Microsoft...
well, do you just have an example for replacing the multiplexer-control with the update-panel?
regards
sascha
