Implementing DragAndDropManager in version 2012.1.326.40

[Igor Stefanovic]

I have problem with using DragAndDropManager for Telerik version 2012.1.326.40. Recently I find out that one of my old projects has problem with drag end drop with some list boxes. It was using RadDragAndDropManager to handle drag and drop. So I switched to DragAndDropManager. However in 2012.1.326 version of controls there is no DragDropPayloadManager. All examples are using this class to pass data so my question is can I implement DragAndDropManager in this version of controls and how to replace DragDropPayloadManager.

Hi Igor,

You could use the DataObject class to pass the desired data and replace the DragDropPayloadManager. For example check the implementation below:

private void OnDragInitialize(object sender, DragInitializeEventArgs args)
{
    ...
    DataObject dragData = new DataObject(yourData);
    dragData.SetData("DragDropData", args.OriginalSource);
    args.Data = dragData;
    ...
}

However, we suggest you to consider upgrading your application to a higher version in order to get advantage of all new features and controls provided by the suite including the DragDropPayloadManaged. You could also check the following article that provides detailed information how to migrate to the DragDropManager:

Hope this helps.
