is the comboxbox slection changed event? Fill the text box with the name selected or what?. You need to store the information from the database to some local storage like dataset or an object list, if you need to retrieve more information based on the name selected and fill the text box.

Customer Add= New Customer? Then how you know his name in the selection list. I think I am not well understood your question

In this event: ComboBox.SelectedIndexChanged Event[^]

Something like:

VB

Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged

        Dim selectedEmployee = CType(ComboBox1.SelectedItem, String)
        TextBox1.Text = TextBox1.Text & Microsoft.VisualBasic.vbCrLf & selectedEmployee 

End Sub
