Cathi can you give me your opnion in this please.

I am using DataBinding to bind my DS to my WindowsForms Objects, in fact I hate the databinding but I see it usefull in one thing which is less code!! & not more than that, any how....

When I add a new row to my DS, I have no problem (if I don't have to update any field manualy) if I do, I have to add 2 rows and at the end of the stage I remove one of them, I don't see it as practical. the resone for that, I am using the next code to add new row and reset the form field at the same time:

Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
With BindingContext(myDS, "Company")
.AddNew()
.Position = .Count - 1
cbSelect.SelectedIndex = .Count - 1
End With
End Sub

the advantage of this code is because of databinding the text field in the form will be empty because it will be binded to a new row.

But if I want to add values to some fields manualy at the same time, it will not allow me.
So, I have to add the following code with the above code, when Save button click:

With myDS.Tables("Company")
Dim tmpDR As DataRow = .NewRow
tmpDR("CompanyID") = strCompanyID
tmpDR("Entered") = Now
tmpDR("companyname_e") = Me.txtCompanyName_e.Text
tmpDR("Email") = Me.txtEmail.Text
tmpDR("PostalAddress_e") = Me.rtbPostal.Text
tmpDR("Location_e") = Me.rtbLocation.Text
.Rows.Add(tmpDR)
End With

This way 2 rows added to the DS, so I delete the first added row:
' The added Row in the "Add" Sub will be removed
With BindingContext(myDS, "Company")
.RemoveAt(iRow)
End With

Do you have any idea to allow me to use databinding & manual if adding method?
