Combo box issue

Hi,

I had two combo boxes that are databound to the same array of objects.

So both combo boxes has the same list of objects, but they are to be independent of each other on the same form

I had the second combobox with the event SelectIndexChanged.

Somehow whichever combobox index is changed, the other will follow.

This two same selections still happened even without the SelectedIndexChanged event

Has anyone had this problem before?

Re: Combo box issue

Hi,

You need to have two separate data sources defined

Public Class Form2
    Dim DS As New NorthwindDataSet
    Dim DtCust As New NorthwindDataSet.CustomersDataTable
    Dim DtCust2 As New NorthwindDataSet.CustomersDataTable
    Dim DACust As New NorthwindDataSetTableAdapters.CustomersTableAdapter

    Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        DACust.Fill(DtCust)
        DACust.Fill(DtCust2)
        ComboBox1.DataSource = DtCust
        ComboBox1.DisplayMember = "CompanyName"
        ComboBox1.SelectedIndex = 0
        ''
        ComboBox2.DataSource = DtCust2
        ComboBox2.DisplayMember = "CompanyName"
        ComboBox2.SelectedIndex = 0
    End Sub
End Class
