DevExpress 给TreeList添加右键菜单

只有在右击节点时才会触发

private void treeList1_MouseDown(object sender, MouseEventArgs e)
{

if (e.Button == MouseButtons.Right)
{
treeList1.ContextMenuStrip = null;

TreeListHitInfo hInfo = treeList1.CalcHitInfo(new Point(e.X, e.Y));
TreeListNode node = hInfo.Node;
treeList1.FocusedNode = node;
if (node!=null)
{
treeList1.ContextMenuStrip = contextMenuStrip1;
}
}

}

添加BarManager和popupMenu组建:

设置popupMenu组件的Manager属性:
