推荐答案

Quote：

(DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'SelectedQuantity'.)

错误很明显。



它说 DataSource ，它被绑定到 ListView 不包含任何列' SelectedQuantity '。



请将该列添加到 DataSource （在查询中从数据库获取数据），以便在 Mark-up 中使用它。

The error is quite clear.

It says the DataSource, which is getting bound to the ListView does not contain any column 'SelectedQuantity'.

Please add that column to the DataSource (in the Query fetching the data from Database) in order to use it inside Mark-up.
