How to get index of an item in the DropDownByKey control?

Question

Hi,
I'm new to PDK for .NET and I have a simple question about the "IndexOf" method of the items collection.
Attached a small test program:
Dim li As New DropDownListItem
li.Key = "A"
li.Text = "Zero"
DropDownByKey1.Items.Add(li)
li = New DropDownListItem
li.Key = "B"
li.Text = "One"
DropDownByKey1.Items.Add(li)
li = New DropDownListItem
li.Key = "C"
li.Text = "Two"
DropDownByKey1.Items.Add(li)
li = New DropDownListItem
li.Key = "D"
li.Text = "Three"
DropDownByKey1.Items.Add(li)
li = New DropDownListItem
li.Key = "E"
li.Text = "Four"
DropDownByKey1.Items.Add(li)
Dim liForSearch As New DropDownListItem
liForSearch.Key = "C"
liForSearch.Text= "Two"
Write(" Index --> " & DropDownByKey1.Items.IndexOf(liForSearch))
The output should be 2 but instead I get -1 (Not Found).
Why?
thanks,

Hi,
Since you have the Key of the listItem you are looking for you should get the item by applying:
liToSearch = DropDownListItem.Items[key];
int index = DropDownListItem.Items.IndexOf(liToSearch);
