Methods:
- ReinitializeDragControls()
Perform re-initialization of drag controls in the WebDragDropExtender control. You will need to call this method whenever the drag control is refreshed/updated using AJAX callback. For instance, this method needs to be called in OnResponse client side event of WebGrid so the drag behaviors are initialized back to the WebGrid after its refresh (partial updates). For example of this usage, see the Scenario 1 - Outlook Style Drag and Drop sample. -
ReinitializeDropControls()
Perform re-initialization of drop controls in the WebDragDropExtender control. You will need to call this method when the drop control is refreshed/updated using AJAX callback. For instance, if the WebExplorerPane items are removed or added using AJAX, the changes won't take effect until this method is called. -
ClearDropControlCache()
Clear the cache of the drop controls. The drop controls are cached in many ways internally by WebDragDropExtender to provide a high performance drag-drop solution. However, when the drop control's properties are modified, for instances, its location or sizes, you need to call this method to invalidate the cache.
