[VB]

Imports GrapeCity.Win.MultiRow

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Dim comboBoxCell1 As New ComboBoxCell
    comboBoxCell1.Name = "comboBoxCell1"
    comboBoxCell1.Items.Add("Tokyo")
    comboBoxCell1.Items.Add("Nagoya")
    comboBoxCell1.Items.Add("Osaka")

    GcMultiRow1.Template = Template.CreateGridTemplate(New Cell() {comboBoxCell1})
    GcMultiRow1.SetValue(0, "comboBoxCell1", "Nagoya")
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim gcMultiRow As GcMultiRow = Me.GcMultiRow1
    If TypeOf gcMultiRow.CurrentCell Is ComboBoxCell Then
        Dim comboBoxCell As ComboBoxCell = TryCast(gcMultiRow.CurrentCell, ComboBoxCell)
        Dim selectedValue As Object = comboBoxCell.Value
        Dim selectedIndex As Integer = -1
        If Not selectedValue = Nothing Then
            selectedIndex = comboBoxCell.Items.IndexOf(selectedValue)
        End If
        MessageBox.Show(String.Format("Selected Index: {0}", selectedIndex))
    Else
        MessageBox.Show("Present cell is not ComboBoxCell.")
    End If
End Sub
