Similarly as in the example when custom handle
client-side event where we set the handle of the RadDock to the desired HTML element. The Image is added to the dock's content twice: once when the dock is created for the first time and second time when the dock is recreated in the Page_Init.
For your convenience I modified one of our online demos for dynamically created docks
, where I set the handle to an image placed inside the RadDock. You can find it attached to thread.
