How to make the columns in a ListView expand dynamically?

ColumnHeader header = new ColumnHeader();
header.Text = "";
header.Name = "col1";

listView1.Columns.Add(header);
listView1.View = View.Details;
listView1.Scrollable = true;

readableRss = RssReader.covertRss("http://rotter.net/rss/rotternews.xml");

lines = Regex.Split(readableRss, "\r\n")
                   .Where(str => !string.IsNullOrEmpty(str))
                   .ToList();

for (int i = 0; i < lines.Count; i++)
{
    listView1.Items.Add(lines[i]);
}

This is what im getting:

I need to use the mouse to move the Column/s to the right so i will see all the line/s. How can i make it automatic so each line the column will be spread/open to the right so it will show the entire line ?

Adding this line: header.Width = 1000; solve it. But how do i know how much to set it to ? 1000 is good in this case but why not 999 or 1500 ? I just guessed that the width should be 1000

Add that line to make the column resize based on content:

header.AutoResize(ColumnHeaderAutoResizeStyle.ColumnContent);

You need to add it after you have added all the items.

You need to use the ColumnHeader's AutoResize method, which will,

Resize the width of the column as indicated by the resize style.

So, something like this,

header.AutoResize(ColumnHeaderAutoResizeStyle.ColumnContent);
