QuestionProblems add a new record to a DataSet using the BindingNavigator Control Pin
Quecumber25618-May-07 4:11

Hi Everyone:
I have solved the problem of how to bind a DataSet to the BindingNavigator control thanks to those who guided me in the right direction.

I now have another problem that is causing me ulcers.

When I populate the DataSet with data I retrieved from some table. I have no trouble using the move next, move previous, move first and move last buttons on the BindingNavigator control. I can navigate from record to record with no problem.

When I try to add a new record into the dataset using the routine written below; two problems occur. 1 – The auto increment ID number goes from 5(the last record ID in the Dataset) to 7. What happened to 6? 2 – After I add the new record’s data; when I page back through the dataset’s records the new record I just added has the record ID of 7. When I move to the previous record 6 (the one that was skipped) I see the data for the first record in the dataset. Records 5 to 2 seem to be correct, but record 1 is empty.

Code Snippet:
Private Sub New_Bindings(ByVal intOrdinal As Integer, _
ByVal strCode As String, _
ByVal strName As String)

Dim tblBindings As DataTable
tblBindings = MyDataSet.Tables("tblBindings")
Dim drCurrent As DataRow
drCurrent = tblBindings.NewRow
drCurrent("Ordinal") = intOrdinal
drCurrent("BindingCode") = strCode
drCurrent("BindingName") = strName
tblBindings.Rows.Add(drCurrent)
Call Clear_Form()
End Sub

Logic dictates when I add a new record to the dataset it is added at the end of the dataset. This doesn’t seem to be happening. What I plan on doing is after I update the Dataset I will use the DataAdapter to write the changes back to the SQL Sever database, but the dataset looks incorrect, so I won’t commit an update until I’m sure the dataset’s information is correct.

A corollary to this problem is when I try to add records to an empty dataset. I get the DBNull error.

Does anyone know how to add a new record to: 1) an existing dataset, or 2) an empty one?

Thanks,
