Difference |

(For all supported draggable controls except the TreeView and ListView controls) The icon of the mouse will not change, if it is not on the client area of a control. (For TreeView and ListView) When you drag a control, you cannot see the mouse icon during the drag. PowerServer does not support dragging and dropping multiple controls simultaneously. You can only drag and drop one control at a time. |
