Hey guys,
I've added a list of items to a listbox in my C#/ASP web form. I allow
the user to select a few items, and then click a button. I want to be able to
retrieve the items from the list box that THAT user has selected and write it
to a string.
This is what I'm doing to read the text and it's not working:
protected void Button1_Click(o bject sender, EventArgs e)
{
string strTemp;
foreach (ListItem lstItem in ListBox1.Items)
{
strTemp = lstItem.Text;
if (lstItem.Select ed = true)
{
strTotString = strTotString + "," + strTemp;
}
}
}
Any idea what I'm doing wrong?
Not matter how many or what I highlight, it keeps giving me the very first
item in the list box (whether or not I've actually highlighted it).
Thanks! 2 1063

2 things:
If there is a property named SelectedItems, I would use that to iterate
through.
Your IF statement is a little funky :) You have if (lstItem.Select ed =
true) instead of if (lstItem.Select ed == true). To avoid this, I just use
if (lstItem.Select ed) ... unless I have to of course ;)
HTH,

Thanks Mythran, I appreciate the advice and the info.
However, it still does the same thing.
When I run my form, I'll highlight a couple of items on the list box, and
then click a button which runs this code:
protected void Button1_Click(o bject sender, EventArgs e)
{
string strTotString;
string strTemp;
strTotString = "";
foreach (ListItem lstItem in ListBox1.Items)
{
strTemp = lstItem.Text;
if (lstItem.Select ed == true)
{
strTotString = strTotString + "," + strTemp;
}
}
tBxComments.Tex t = strTotString;
}
After that code is run, what actually happens is that the VERY FIRST item in
my listbox is the ONLY item that will end up being the value of
strTotString... EVEN if I didn't select that item.
What I basically want to do is retrieve a list of all the items that I've
selected (highlighted) from a listbox that I have. What could I be doing
wrong? I just don't get it.
Thanks!!!

Hi, All,
I'm using MS.net 2003 and using a windows.forms.listbox control for my
window application but I don't know why the Horizontal Scrollbar could NOT be
shown even if I set HorizontalScrollbar = true. The text info in listbox
already beyond its right edge. How can I see the hidden part info in listbox?
here is a part of codes.

Hi all,
After unsuccessfully trying to make my own dual listbox control out of
arraylists, I decided to look for a 3rd party control. I've looked for over
a week now and can't find anything but ASP.Net stuff when I need a Windows
Form control. I've seen dual listbox populators in countless Windows
applications, and have seen them run very fast, so I figured this would be
extremely popular.
Here's how it should work:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
