Currently there is a known issue with Drag and Drop
control. Can you please let us know if your RadDiagram
is wrapped within a RadDocking
control? If it is, we're currently investigating the cause for the issue. In the meantime in order to workaround it you can subscribe to the DragOver
event of the RadDiagram
control and mark it as Handled
. By doing so the Drop
event will be fired the dropped shape will be added to the RadDiagram
. You can use the following code:
sender, Telerik.Windows.DragDrop.DragEventArgs e)
Regarding the second issue, can you please make sure you're using a supported ConnectionType
. With this release there are only a few supported ConnectionTypes
You can find more information regarding these types in our documentation. Before we supported Straight and RoundedConnections but as they are now depreciated they aren't displayed. And if you use any of these obsoleted types, please change them with any of the new supported type. The Polyline connection is the most commonly used type as it by default comes with two ConnectionPoints - start and end points, and therefore it is displayed as a straight connection. In the tutorial I mentioned you can find more information regarding the ConnectionPoints and regarding the new support for rounded connections.
If, however, you're not using RadDocking nor obsoleted ConnectionTypes, I'm afraid we'll have to ask you to elaborate further on your solution and its implementation. As only then we will be able to investigate the case locally.
