Drag and Drop in ListControl Will not fire

[Ken]

Hi:

I'm trying to use the ListControl. I have two on my form and I use the DragDropManager to join them. However, it seems that I am unable to get any of the events associated with drag and drop to fire. I've created them using the properties list and everything in code is correct. Yet if I put a break point in the dragdrop event, it never gets there. (allow dragdrop is set to true).

Anyone know what gives ?

Thanks,
Ken

Hello Ken,

Thank you for contacting Telerik support.

You can refer to our Demo Application (DropDown & List -> List Control -> Drag&Drop example) for a demo on how to move items from one RadListControl to another. From this example you can use the RadItemDragDropManager class in order to provide Drag & Drop between two RadListControls. For example:

RadItemDragDropManager dragDropManager = new RadItemDragDropManager(this.radListBox1, this.radListBox1.Items, this.radListBox2, this.radListBox2.Items);

I hope that you find this information useful.

All the best,

Thanks for the response, Peter.

I am using code from the sample. Visually, it works fine. The items do move from list 1 to list 2. The problem I am having is capturing any of the drag drop events. I've added events for all of them, put a breakpoint in each, and it is never hit.

Hi Ken,

Thank you for writing back.

RadItemDragDropManager class uses its own drag drop mechanism, different than the default OLE drag & drop mechanism. That is why default drag & drop events do not get fired. In this scenario you can use BeginDrag and EndDrag methods of RadItemDragDropManager.

If this does not help, describe in detail the desired functionality and behavior that you want to achieve and we will be glad to help further.

I am looking forward to your reply.

Kind regards,
