I will post here the information that I provided in your support ticket on the matter:
You can use the RegisterStartupScript
method of ScriptManager to register a unique handler function for every RadDock you add dynamically on the page.
Another option is to use the dock
parameter that is passed to the event handler. This parameter contains a reference to the client-side object of the dock, the command of which is clicked. It will allow you to get the current dock and find the element in its content that you want to manipulate.
I would suggest continuing our discussion in the support ticket if you need additional help with configuring the client-side handler.
All the best,
the Telerik team
