Examples

The code below obtains the name of the element located under the mouse pointer. The MouseMove event is handled to track mouse pointer movement.

using DevExpress.XtraTreeList;
//...
private void treeList1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e) {
   TreeListHitInfo hi = treeList1.CalcHitInfo(new Point(e.X, e.Y));
   string elementName = hi.HitInfoType.ToString();
   //...
