Hi, I am new to programming and trying to figure out how to set up a auto populated drop down list for year.

I am trying to set up a drop list of years, starting from 2009 to current year. I have tried to use the code below but it failed.

Can someone please help me to look into the coding and explain to me what I did wrong? Any help is greatly appreciated!

I am using Visual Studio 2005 to programe.

Private Sub cbo_StartYear_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cbo_StartYear.SelectedIndexChanged

        cbo_StartYear.Items.Clear()  'CLEAR THE LIST FIRST
        Dim currentYear As Integer = Date.Now.Year
        Dim i As Integer
        For i = 2009 To currentYear
            cbo_StartYear.Items.Add(i)
        Next i
        cbo_StartYear.SelectedIndex = cbo_StartYear.Items.Count - 1
End Sub

推荐答案

就像Om Prakash所说的那样，您应该将此代码放在Form_Load或Control_Load事件中.
就像

As Om Prakash said, you should put this code in Form_Load or Control_Load event.
Just like,

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        cbo_StartYear.Items.Clear()  'CLEAR THE LIST FIRST
        Dim currentYear As Integer = Date.Now.Year
        Dim i As Integer
        For i = 2009 To currentYear
            cbo_StartYear.Items.Add(i)
        Next i
        cbo_StartYear.SelectedIndex = cbo_StartYear.Items.Count - 1
End Sub
