ListBox

controls

Hello , I am new at visual basic 2012 and i have an issue with the list box control selected item

I have a data base with 3 tables 1.Doctors 2.Names 3.NamesHolidays .
I create a data set with the 3 tables and their relations , i drag to the form the doctors Table as details.

I replace the NameId textbox with a combobox with the following parameters
• DataSource : NamesBindingSource
• DisplayMember : Description
• ValueMember : NameID
• SelectedItem : DoctorBindingSource - NameID
And i have a look up field filled up with the values that they are in the Names Table i select one and the NameID is stored to the doctorsTable.

After this i replace the NameHolidayID text with a listbox with the following parameters
• DataSource : FKHolidaysNamesNamesBindingSource
• DisplayMember : Date
• ValueMember : HolidayID
• SelectedItem : DoctorBindingSource - HolidayNameID

So now every time i choose a different doctor from the DoctorBindingNavigator Toolbar the selected name at the combo box is changed , the values to the listbox are changed to the right values for the specific name

But the problem is that the selected item at the ListBox is always the first item at the list and not the item that is stored at the HolidayNameID at the doctors Table.

I wrote no code the visual basic inserted a few lines of code to fill the tableadapters
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Me.HolidaysNamesTableAdapter.Fill(Me.PhysioDataSet.HolidaysNames)
Me.NamesTableAdapter.Fill(Me.PhysioDataSet.Names)
Me.DoctorTableAdapter.Fill(Me.PhysioDataSet.Doctor)
End Sub


I hope to describe the problem well...Thanks is advance for your time.
