Type Description

A TreeListHitInfo object which contains information about the Tree List’s elements located at the test point.


Use the CalcHitInfo method to determine which element is located at a specified point. For instance, this can be used when handling the Tree List’s Click event to determine which element was clicked. In such instances, pass the current mouse pointer’s coordinates as the method’s parameter.


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();
