代码编号:长描述

如果下面的代码注定失败，我还有什么其他选择?

If the below code is doomed to fail what other alternatives do I have?

推荐答案

我猜 LongDescription 或 CodeNumis 是只读属性(不是有公共二传手).您需要将绑定更改为您在 Run

I'm guessing that either LongDescription or CodeNumis is a read-only property (doesn't have public setter). You need to change binding to be one way for all read-only properties that you use in Run

<Run Text="{Binding LongDescription, Mode=OneWay}"/>
