使用PopupContainerEdit和PopupContainerControl制作下拉菜单树小记

转自：http://jlcon.iteye.com/blog/898210  

首先拖动一个PopupContainerEdit控件和PopupContainerControl控件到界面上，在PopupContainerControl中拖动一个TreeList控件，设置TreeList控件的OptionsView属性，我的设置为

                                       
 

  设置TreeList控件的OptionsView属性                              设置TreeList的OptionsSelection属性：                   

 

                                                   

 设置TreeList的OptionsBehavior属性，使其不可编辑：          然后设置PopupContainerEdit的PopControl属性

                                                                                                    使其与PopupContainerControl组件关联

 为TreeList添加FocusedNodeChanged事件

private void treeList2_FocusedNodeChanged(object sender, FocusedNodeChangedEventArgs e)
{
       TreeListNode node = e.Node;
            popupContainerEdit1.Tag = node["xxxx"].ToString();
            popupContainerEdit1.EditValue = node[0].ToString();
            popupContainerEdit1.ClosePopup();
}

 选择之后便可关闭弹出框。

 

补充：为了能让PopupContainerControl和PopupContainerEdit的宽度保持一致，需要在PopupContainerEdit上添加QueryPopUp事件处理：

private void popupContainerEdit1_QueryPopUp(object sender, CancelEventArgs e)
{
      PopupContainerEdit popupedit = (PopupContainerEdit)sender;
      popupContainerControl1.Width = popupedit.Width;
}
