Hi Ron,
To enable this scenario, the
IsDropAllowed attached property needs to be set to the individual Cell containers. Currently, there is no direct access to the containers.
In the upcoming release of the RadGridView there will be an event
OnRowLoaded which will allow you to access the individual cells and set the event. Unfortunately I cannot think of a workaround with the current version.
Best wishes,
Miroslav
