当两个列表框都绑定时，如何将内容从一个列表框移动到另一个列表框? [英] How to move contents from one list box to another when both listboxes are bound?

问题描述

foreach (string item in listBoxAvailableStops.Items)
             {
                 if (listBoxSelectedStops.Items.Contains(item) == false)
                 {
                     listBoxSelectedStops.Items.Add(item);
                 }
                 else
                 {
                     MessageBox.Show("These Stops are already selected!");
                 }
             }

这是我的代码，我想将内容从listBoxAvailableStops移至listBoxSelectedStops，但是这两个列表框均已绑定.因此，它将显示一个错误，指示必须首先删除绑定.因此，当两个列表框都绑定时，如何将内容从一个列表框移动到另一个列表框.

谢谢&问候

This is my code and I want to move the contents from listBoxAvailableStops to listBoxSelectedStops, but both of these listboxes are bound. So it will show an error indicating that the binding would have to be removed first. So how can we move the content from one listbox to another when both these listboxes are bound.

Thanks & Regards

推荐答案

而不是直接添加到列表框中，而是添加到基础数据源.列表框的目的是显示绑定数据，然后将其添加到列表中意味着添加到基础数据源.那么，为什么不直接在数据源上执行此操作，第二个列表框将显示它呢?

Hi,

Instead of adding to the list box directly, add to the underlying data source. The purpose of list box is to display the bound data, then adding to it means adding to the underlying data source. So why don''t do it directly on the data source and the second list box will display it
