Intermediate dialog in radlistbox drag and drop

[Julian]

Hi all,

 I am trying to implement a feature whereby the user will drag an item from one list box and when they dump it into the other, before it is dumped, they will get a dialog which will ask them to set one of the properties of the item they wish to transfer. I am currently trying to abuse a dataconverter but it doesn't seem to be working.

 Thanks,

 Julian

Hello Julian,

Thank you for contacting us.

In order to achieve the desired functionality you need to create custom ListBoxDragDropBehavior - you need to override the default implementations of the Drop and DragDropCompleted methods. Inside them using the DragDropState you could get the current dragged/dropped item and change the properties of the item as needed. Please, check the following sample project from our SDK Repository that demonstrates how to override the listed above methods and get the dragged/dropped item:
https://github.com/telerik/xaml-sdk/tree/master/ListBox/CustomListBoxDragDropBehavior

Please, do not hesitate to contact us if you need our further assistance with the implementation of the described above approach.

We hope this will help you.

Regards,
