# SortedList order...

Posted on 2005-04-20

Using a SortedList to diplay the Months in a Dropdown List:

colMonth = New SortedList()
colMonth.Add( "1", "January" )
colMonth.Add( "2", "February" )
colMonth.Add( "3", "March" )
colMonth.Add( "4", "April" )
colMonth.Add( "5", "May" )
colMonth.Add( "6", "June" )
colMonth.Add( "7", "July" )
colMonth.Add( "8", "August" )
colMonth.Add( "9", "September" )
colMonth.Add( "10", "October" )
colMonth.Add( "11", "November" )
colMonth.Add( "12", "December" )

However, when the Dropdown list is displayed it goes in the order of:
<option value="1">January</option>
<option value="10">October</option>
<option value="11">November</option>
<option value="12">December</option>
<option value="2">February</option>
<option value="3">March</option>
<option selected="selected" value="4">April</option>
<option value="5">May</option>
<option value="6">June</option>
<option value="7">July</option>
<option value="8">August</option>
<option value="9">September</option>

Is there anyway of sorting this the right way?

Are you able to put in 01, 02, 03, 04..... ??

If you're taking that value and doing a Convert.ToInt32 on the backend, should work fine.

I could put in 01, 02, 03.

But I was using this routine to select the current date:

Dim intMonth As Integer = Convert.ToString(month(now))

for i = 1 to 12
if intMonth = i then
dropStartMonth.SelectedValue = i
end if
next

This doesnt work if I use 01, 02, 03

how about something like

dropStartMonth.SelectedItem = Month(i)

??

I totally know what you're saying with the sortedlist, but I haven't found it to be all that flexible.

Dim intMonth As Integer = Convert.ToString(month(now))

for i = 1 to 12
if intMonth = i then
dropStartMonth.SelectedItem = Month(i)
end if
next

Results in:

can the key object in the Add method be an int instead of a string?

colMonth = New SortedList()
colMonth.Add( 1, "January" )
colMonth.Add( 2, "February" )
colMonth.Add( 3, "March" )
colMonth.Add( 4, "April" )
