Hi,
I have a list of 6 DropDownList boxes, from DropDownList1 to
DropDownList6, and I'm changing the SelectedIndex of each using a
foreach loop as follows:
foreach(Payment ReqDisplay thispayment in listPaymentReqD isplay)
{
if ((string)thispa yment.TaxType == "FIT")
this.DropDownLi st1.SelectedInd ex =
(int)thispaymen t.PaymentRequir ementID - 1;
if ((string)thispa yment.TaxType == "FUI")
this.DropDownLi st2.SelectedInd ex =
(int)thispaymen t.PaymentRequir ementID - 1;
if ((string)thispa yment.TaxType == "SIT")
this.DropDownLi st3.SelectedInd ex =
(int)thispaymen t.PaymentRequir ementID - 1;
if ((string)thispa yment.TaxType == "SUI")
this.DropDownLi st4.SelectedInd ex =
(int)thispaymen t.PaymentRequir ementID - 1;
if ((string)thispa yment.TaxType == "ETF")
this.DropDownLi st5.SelectedInd ex =
(int)thispaymen t.PaymentRequir ementID - 1;
if ((string)thispa yment.TaxType == "SDI")
this.DropDownLi st6.SelectedInd ex =
(int)thispaymen t.PaymentRequir ementID - 1;
}
The problem is that when I change, say, DropDownList4.S electedIndex =
3; every other DropDownList's SelectedIndex changes as well!?
What am I doing wrong?
Thanks much for your help.

Do all ddls share the same items?
When you set the SelectedIndex property, it actually sets the Selected
property of the item you select. Thus the same item becomes selected in all
ddls it is participating.
The solution is to replicate the item collection for every single ddl.

So you are saying that by setting the SelectIndex of (say) the first
ddl ALL of the ddls in that group get set along with it?
So how do I replicate the item collection for every single ddl? I
don't understand what you mean. Could you give me a code example?
Thanks so much for your help.
Steve
I mean every ddl should have it's own item collection, not shared with the
other ddls.
How do you populate the ddls?
