I'm using strong typed dataset.
The problem ties with datarelation string "BGHuntedBGHarvest." The "KillNo" is one data field in detail datatable. If I remove the binding, the error will show next data field. The error will be gone until I remove all data fields that not in the datarelation columns. Thanks. Ben
This is error message:
************************************************** **************************
BGHarvestBindingSource.DataMember = "BGHuntedBGHarvest"
Cannot bind to the property or column KillNo on the DataSource.
Parameter name: dataMember
