I have a BindingSource(bound to a Entity).

The BindingSource is bound to a Combobox(CostCode) and a Text box(Field Qbdescription )

When someselects a value in the combobox..i populate the value iin the text box.

Public Class Form2
    Dim TransactionToSave = New TblTransactionsEntity
    Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        TblTransactionsEntityBindingSource.DataSource = TransactionToSave
    End Sub

    Private Sub CostCodeComboBoxEdit_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CostCodeComboBoxEdit.SelectedIndexChanged
        Select Case CostCodeComboBoxEdit.EditValue
            Case "4"
                TransactionToSave.Qbdescription = "Here am i44444"  'A
            Case "5"
                TransactionToSave.Qbdescription = "Here am i555"      'B
            Case "6"
                TransactionToSave.Qbdescription = "Here am i666"      'C
        End Select
    End Sub
End Class

The above code works fine except the value selected in the combobox resets to nothing when is executes code at A, B or C

Weird..basicially when TransactionToSave.Qbdescription=<value> the event CostCodeComboBoxEdit.SelectedIndexChanged is triggered again!

The BindingSource is bound to a Combobox(CostCode) and a Text box(Field Qbdescription )

Why do you bind the bindingSource to the TextBox?

Entity TransactionToSave has many properties ..2 being QBDescription and CostCode.

When a user select a value from CostCode combobox..its populates QBDescription with text dependent on what cost code is selected.

I then save the cost code and QBDescription with SaveEntity()..

Please try to call EndEdit() on the bindingSource before setting values from code.

didn't help...

Hmm, which properties of your entity are called when you change the value at A, B or C ?
