DevExpress GridControl未绑定列 [英] DevExpress GridControl Unbound Columns
问题描述
我想知道如何在gridview中正确添加一个未绑定的列。
我在设计器中添加了一个未绑定的列（设置unbound类型，显示格式和全部）
，但每当我运行应用程序时，尝试更改未绑定列的值，并失去其焦点值不保存（即使在更改显示格式时显示格式无法正确显示）。
I would like to know how to properly add a unbound column into a gridview. I've added a unbound column in the designer (set the unbound type, display format and all) but whenever I run the application, try to change the value of the unbound column and loses its focus the value is not saved (even the display format is not displaying correctly when I'm changing it).
我一定要做错事。我需要帮助的人！

Instead, the GridView publishes the CustomUnboundColumnData event which can be used to provide data to the unbound column and also save it. The help topic contains the example of how to use this event. Also, you will find a lot of useful information abound unbound columns at:
