Hi all,

What i need is a way to store an ID with a text label in a combobox format...

Exactly the same thing as a combobox in HTML

How can I do this in my windows VB application?

You can use the ItemData property for this. This can contain numerical values for each item.


    Dim l_lIdx As Long    

    For l_lIdx = 1 To 10

        Call Combo1.AddItem("Item " & CStr(l_lIdx))

        Combo1.ItemData(Combo1.NewIndex) = 100 + l_lIdx


Private Sub Combo1_Click()

    Debug.Print Combo1.ItemData(Combo1.ListIndex)

End Sub

Hi drxav;

In Windows Forms the ComboBox.ValueMember is used to hold data with the associated items in the drop down list. This member, ValueMember, needs to be a property of the bound data source. This means to use ValueMember you need to use the DataSource of the ComboBox and not just adding items to its list.

See code snippet to for example of its use.


Public Class Form1

    Public Class ComboBoxItems

        Private _item As String

        Public Property ItemMember() As String


                Return _item

            End Get

            Set(ByVal value As String)

                _item = value

            End Set

        End Property

        Private _value As String

        Public Property ValueMember() As String


                Return _value

            End Get

            Set(ByVal value As String)

                _value = value

            End Set

        End Property

    End Class

    Private cbiList As New List(Of ComboBoxItems)()

    Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object, _

        ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged

        ' The Selected item and vale was

        Dim item As String = CType(Me.ComboBox1.SelectedItem, ComboBoxItems).ItemMember

        Dim value As String = Me.ComboBox1.SelectedValue

        MessageBox.Show("Selected Item is = " & item & " and the Value Member is = " & value)

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim cbi As ComboBoxItems

        RemoveHandler ComboBox1.SelectedIndexChanged, AddressOf ComboBox1_SelectedIndexChanged

        For idx As Integer = 0 To 10

            cbi = New ComboBoxItems()

            cbi.ItemMember = "Item Number " & idx.ToString()

            cbi.ValueMember = idx.ToString()



        ComboBox1.DataSource = cbiList

        ComboBox1.DisplayMember = "ItemMember"

        ComboBox1.ValueMember = "ValueMember"

        AddHandler ComboBox1.SelectedIndexChanged, AddressOf ComboBox1_SelectedIndexChanged

    End Sub

End Class
