Private Sub ValidateComboItem(ByVal comboName As ComboBox)
        Dim comparetext As String
        If Not comboName.Text = String.Empty Then
            Dim ItemFound As Boolean = False
            For i As Integer = 0 To comboName.Items.Count - 1
 
 
                If comboName.Items(i).ToString = comboName.Text Then
                    ItemFound = True
                End If
            Next
            If Not ItemFound = True Then
                comboName.Text = String.Empty
                ErrorProvider1.SetError(comboName, "Value cannot find from list")
            Else
                ErrorProvider1.SetError(comboName, Nothing)
            End If
            ItemFound = False
        End If
 End Sub
