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

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

 

     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

C#代码  

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

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：

 

C#代码 

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

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