Why am I getting false positives on my WinForms 2015?

Testing for dataset changes on form closing in WinForms 2015.

    If DS.HasChanges Then
            ChangesMade = True
             'Call Option to save code
        End If
        For Each dr As DataRow In DS.Tables("tCARDS").Rows
            If dr.RowState <> DataRowState.Unchanged Then
                ChangesMade = True

            End If
            If dr.HasVersion(DataRowVersion.Proposed) Then
                ChangesMade = True
            End If
        Next

Open in new window

The trouble is that when the user moves between datarows using a datagridview or bindingnavigator the Dataset is marked as changed. It also shows the rowstate as being modified when it isn't. The user isn't changing anything just navigating amongst records. I'd like to figure out how to check for any true changes rather then getting the false positive?

Any ideas?

Thanks

I left the program without an auto save notify feature. The only work around I could think of was to manually track changes by cloning the dataset and looping the rows comparing to the original dataset to see if there changes. Seemed like a lot of work for a fairly common feature in programs. Especially when it would seem like there is already a simple method to do so.

In the end it just wasn't feasible for this program and nobody piped up with thoughts so yeah, if you have any ideas I would still like to implement this in future programs?

Thanks!
