I'm working on one of my first projects. I have a listbox where I select multiple values and I would like to add each selection (selectedItem.Text) to a list of strings.
so far what I was working on is something like ..
selectedItem = new List<string>();
var value = lstpdfList.SelectedItem.Text;
for (int i = 0; i < lstpdfList.SelectedValue.Count(); i++)
{
selectedItem.Add(value);
}
I would really appreciate any advice.
Iterate each item from ListBox.Items collection
foreach (ListItem item in ListBox1.Items)
{
if (item.Selected)
{
selectedItem.Add(item.Text); // selectedImte.Add(item.Value);
}
}
There is SelectedItems property of ListBox, try to iterate throught it. For example, if there is strings in your ListBox, then your code might look like this:
selectedItem = new List<string>();
foreach (string value in lstpdfList.SelectedValues)
selectedItem.Add(value);
You can just cast them to strings:
var selectedItems = listBox1.SelectedItems
.Cast<string>()
.ToList();
If you have populated your ListBox with something other than just strings, just cast to whichever type you need, like so:
var selectedItems = listBox1.SelectedItems
.Cast<WhateverYourTypeIs>()
.Select(item => item.ToString())
.ToList();
