Drag Drop external item onto RadTreeView

[Abhilash]

Hi,
[To whomsoever it may concern]
I am using RadTreeListView in my application and need to support drag-drop of external file from filesystem onto any node of tree view.
Once i drop file onto Node, i need to find the node and update its children by reading file contents. 

Could you help me achieving the following:
1. Need to find event on external item drop which will help me identify target node. Currently I am able to get the file contents on drop event of tree view but not able to figure out target node.
2. Allowing file drag onto parents nodes and not on any of the child nodes, since child nodes are generated based on contents of file.

Thanks in advance!

Regards,
Abhilash

Hi Vlad,
Thanks for your resonse.
I have seen this demo, however this does not allow you to drag drop items from file system. I need to drag specific file from file systetm onto specific node of RadTreeView. For details, please read through first post in same thread.

Hello Abhilash,

 You might want to look at this help article, demonstrating how to enable dragging from external program. Then you can integrate it in the TreeListView using the code from the sample posted earlier in the thread.

Hi Tsvyatko,
The link that you provded explains handling drag drop of external file on WPF. My application is Silverlight app.

Also I have read through:
http://www.telerik.com/help/silverlight/raddraganddrop-getting-started-with-drag-and-drop.html
http://www.telerik.com/help/silverlight/raddraganddrop-getting-started-scenarios.html

But there is no link which explains scenario of external file drag drop on RadTreeListView.
Also I have tried regsitering events DropQueryEventand DropInfoEvent like:

 

radTreeListView.AddHandler(RadDragAndDropManager.DropQueryEvent, new
EventHandler<DragDropQueryEventArgs>(OnDropQuery),
true);<BR>
radTreeListView.AddHandler(RadDragAndDropManager.DropInfoEvent, new
EventHandler<DragDropEventArgs>(OnDropInfo), true);

 

 

However these events were not raised when drag and droped any item from file system.
It would be really nice if you can redirect me to relevant link or send sample POC across.
