Drag&Drop between RADgridview to itemcontrol

[Senthil kumar]

currently, i am using on telerik RAD control version 2013.2.724.40. my assignment is to implement the dragdrop from RADGridview to itemcontrol. The itemscontrol contains a RADCartesianChart and when dropping a row from datagrid to itemcontrol to show the new chart for the related selected row.
suppose, when dropping the selected row item in existing RADCartesianChart, then new lineseries and y-Axis (multiple Y-axis) to be created in same chart. (it will share same X-axis). if user drops the selected row out side the RADCartesianChart (but, within the itemscontrol), then created new chart with in the item control. 

i have created ItemControlDragDropBehaviour as same as suggested in telerik's example. so, it works fine with itemscontrol. but, when i dropping the selected item with in existing chart in the itemscontros, it is not give the dropped chart control.

how to find the chart control when dropping in exact chart control when dropping over the chart control in the itemscontrol.
