ListBox selected item

[David De Cotis]

Hello all, I am trying to go through a ListBox and verify if am item was
selected. If an item was selected, I would like to get a handle of the item

and simply do a response.write on the selected handle. The issue that I am

facing is that I am going each item, but my code does not catch the selected

item. Can anyone please take a look at the code and let me know what I am
doing wrong.

If listBox1.Items. Count > 0 Then
For intCount = 0 To listBox1.Items. Count - 1
If listBox1.Select edIndex = True Then
Response.Write( listBox1.Select edIndex)
End If
Next
End If
B.T.W. this is the way the listBox is defined in the .NET HTML page:

<asp:listbox id="listBox1" runat="server" Width="200px"
Height="142px"> </asp:listbox><BR >

Um, the listBox1.Select edIndex holds the index of the selected item, so what
are you trying to do?

You don't need to loop through the listbox, just use listBox1.Select edItem,
and by the way, listBox1.Select edIndex isn't a true/false, it's the index
number, starting with 0 of the item selected. So, if the first item was
selected, SelectedIndex would be 0, and if the 8th item was selected,
SelectedIndex would be 7.

David,

If you are trying to catch this information in the selectedindexch anged
event, ensure that the listbox's autopostback feature is enabled. I
was unsure if when you were trying to capture this information, so
simply wanted to put that out there in case that method was being
attempted.

Thanks, that is what I thought, but I got sidetracked because when I click
on the button getSelectedItem _Click (see code below) the page seems to
refresh and thereafter the selection that I made on the listbox is not
selected anymore and also the response.write only writes "You have selected
the following item: " and nothing else. It is like when I click on the
button getSelectedItem _Click everything is resetted. Can anyone please give
me an explaination.
Private Sub getSelectedItem _Click(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles getSelectedItem .Click
Response.Write( "You have selected the following item: ")
Response.Write( listBox1.Select edItem)
End Sub
Many thanks to all.

Are you resetting something in the Page_Load method?

Thank-you Craig, You hit it right on the mark. In the Page_Load method I
was reading my listbox entries from another posting and thereby creating the
new listbox for the current posting. Obviously, then my selectedindex would
always return nothing. when I place
Response.Write( "You have selected the following item: ")
Response.Write( act_quest_ListB ox.SelectedItem ) In the Page_Load method it
works. My question, how can I call my function from a button without having
my page reloaded????

Thank-you all
