I have a combobox that is bound to a objectdatasource. The combobox is used as a lookup.
My problem is everytime the combobox looses its focus it reverts to an empty string. The selection disappears (text.property will result to empty string). This is very weird.
Any ideas?

My Code Below:
Code:
Public Class frmUsers_AddEdit
Private newUser As Users
Private usertypeList As List(Of UserType)
Private Sub LoadComboboxes()
Try
usertypeList = UserTypeDB.GetUserTypeList
UserTypeComboBox.DataSource = usertypeList
Catch ex As Exception
MessageBox.Show(ex.Message, ex.GetType.ToString)
End Try
End Sub
Private Sub frmUsers_AddEdit_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.LoadComboboxes()
UsersBindingSource.Add(newUser)
End Sub
end class
Databindings of my UserTypeComboBox:
UserTypeComboBox.DataSource = UserTypeBindingSource
UserTypeComboBox.DisplayMember = UserType
UserTypeComboBox.ValueMember = UserTypeID
UserTypeComboBox.SelectedValue = UsersBindingSource - UserTypeID
