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：

右键点击popupMenu主键，点击Customize选项添加菜单：

然后便可添加到鼠标事件中，此处以TreeList为例：

C#代码

1. privatevoidtreeList1_MouseUp(objectsender,MouseEventArgse)
2. {
3. TreeListtree=senderasTreeList;
4. if(e.Button==MouseButtons.Right
5. &&ModifierKeys==Keys.None
6. &&treeList1.State==TreeListState.Regular)
7. {
8. Pointp=newPoint(Cursor.Position.X,Cursor.Position.Y);
9. TreeListHitInfohitInfo=tree.CalcHitInfo(e.Location);
10. if(hitInfo.HitInfoType==HitInfoType.Cell)
11. {
12. tree.SetFocusedNode(hitInfo.Node);
13. }
15. if(tree.FocusedNode!=null)
16. {
17. popupMenu1.ShowPopup(p);
18. }
19. }
20. }
