Can anyone help me with this problem



I have a dropdown list of states the value is the 2 char state code and the 

text is the state name. When I go from one form to another I want to select 

the state of the previous form.



I am using the following code to do this



  Dim objListItem As ListItem

  Dim objListControl As ListControl

  Dim strState As String



  objListControl = BillingState ' this is the id of the dropdownlist



  strState = "NY"



  objListItem = objListControl.Items.FindByValue(strState)

  objListItem.Selected = True



When I execute this I get this error



System.Web.HttpException: A DropDownList cannot have multiple items selected





I have got this code to work before but the values were numbers any help 

please



Thank You

Chuck

What you are trying to do is to add a selected item to the selected 

items list. this is only possible to do when selection specification is 

set to "multiple".

What you need to do is ONE of the following:



1. call the ClearSelection() method before setting selection



2. set the selected index property of the list control according to the 

index of the item you want to select. you can find the item's index 

using Items.IndexOf(item) - watch out not to set the VALUE of the item, 

but its INDEX in the list



regards,

Ziv.
