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