dynamic dropdownlist

I'm trying to create a dynamic dropdownlist, not in a datagrid, that populates the list based off of the current month, and then the previous 11 months. I've got it working to the point that it does populate the ddl, but then it is refilling it.

Does anybody know of a good resource that shows how to do this?

Are you clearing your list before you populate it again? Can you post your code?

Good luck

Sub setDropDownList()
ddlTimeFrame.Items.Clear()
Dim monthArray() As String = {"January", "February", "March", "April", "May", "June", "July", _
"August", "September", "October", "November", "December"}
Dim testDate As Integer
Dim strMonth As String

Dim count As Integer = 0
myDate = myDate.Today()
testDate = myDate.Month()

While count < 12
testDate -= 1
strMonth = CStr(monthArray.GetValue(testDate))

ddlTimeFrame.Items.Add(strMonth)
Page.FindControl("phTimeFrame").Controls.Add(ddlTimeFrame)
If testDate = 0 Then
testDate = 12
End If
count += 1
End While
End Sub

I added the ddlTimeFrame.Items.Clear() but it is still refilling it

Are you calling this funtion inside or outside an

if (not IsPostback) then

end if

constructor?
