I found the attached TreedGridHelper sample in the forum while searching for hierarchial representation of self reference. The sample grid is good and Iam trying to manage the hierarchial relationship using Drag and Drop.When I drag and drop the item in the hierarchy, the value of column "Related To" of dragged item should be changed based on where it is dropped.
Ex : In the sample if I drag and drop 5th row (Parent Id 4 )to 3rd row (Parent Id 2), then the Related To value of the dragged record (Parent Id 4 ) should be changed to 2 from 3. ie. Before drag and drop 4 is a child of 3. After drag and drop 4 and 3 should be siblings.
Thanks and Regards,
Chakravarthi
