DataList jumps to next in list

I have solved my previous problem but face a new one now. Perhaps someone can help.

I have a MS SQL 2000 database. I use two tables from that database. Two different ADOdc's connect to a table. One table contains information about companies and the other contains contactpersons from those companies.

In my form I have a DataCombo with following properties:

BoundColumn = Companyname
DataField = Companyname
Datasource = Contactpersons
ListField = Companyname
RowSource = Companies

Also in my form is a DataList and properties are:

BoundColumn = Companyname
DataField = NameOfContact
Datasource = Contactpersons
ListField = NameOfContacts
RowSource = (is empty)

A third ADOdc called Name, is used to store the rows that are the same in both tables, resulting in a list of contactpersons for a specific company.

Code in the form is:
VB Code:
Option Explicit
 
Private DeleteContact As String
 
Private Sub DataCombo1_change()
Dim query As String
    
    gstrContact = DataCombo1.Text
    
    query = "SELECT * FROM Contactpersons WHERE CompanyName = '" & gstrContact & "' ORDER BY Name"
    
    Name.RecordSource = query
    Name.Refresh
    Set DataList1.RowSource = Name
    DataList1.Refresh
 
End Sub
 
Private Sub Form_Load()
 
ContactPersons.Recordset.AddNew
    
    DataCombo1.Text = ""
 
End Sub
Now what is the problem?

When the form opens, I can go to DataCombo1 and select a company. When a company is chosen, all the contacts of that company are visible in DataList1.

I then select a name by clicking it.

And then the problem comes.

When I push a button that I have on my form, the NEXT name in my DataList1 gets selected. Why, I don't know. It's like a lostfocus was written somewhere to jump to the next one in the list. I cannot seem to find the solution.

I wanted to delete the selected person, but because the next one in the list gets selected when I push the delete button, the wrong person gets deleted.

Good thing I made a backup of my database before trying this.

Anyone who can help?
