Hello Zeeshan,
I have already answered your other support ticket - for your convenience I pasted below my answer.
The RadTooltip controls is not draggable and only a single tooltip might be visible at any given time. This behavior is by design and will not be changed as changing it would defy the purpose of the control.
The purpose of a tooltip is to provide additional information for a given element.
It is not meant to be used as a popup control or as a draggable panel. For this purpose we provide RadWindow and RadDock controls. Both of these controls are draggable, and allow for more than one visible element of the kind on the page.
It is not possible to use a drag panel extentender to make tooltip draggable as the tooltip UI is constructed dynamically on the clientside, and it does not reside at the tooltips' original server location.
Our suggestion is to consider using RadWindow and RadDock, both of which are available in the Prometheus suite.
All the best,
George
