I wanna add details to watchers column like my following image.. I use following code to add those details.But it prints in 1st column.. could anybody tell me to do this.

Here's the code I've used:

private void addwatchers(string watchers)

 string row = watchers ;
 ListViewItem item = new ListViewItem(row);
 //ADD ITEMS
 listView1.Items.Add(item);


private void button2_Click(object sender, System.EventArgs e)

 string cwatchers = richTextBox2.Text.Split('n');
 for (int i=0;i<cwatchers.Length;i++)
 
 addwatchers(cwatchers[i]);
 

Every time you call addWatchers() you create a list view item (a row in the list view). You have several ways of creating such items. The one you're currently using is passing an array of string, which represents the column values (by position) to create each item.

What I'd do is to create the ListViewItem in the caller method instead:

for (int i = 0; i < cwatchers.Length; i++)

 var item = new ListViewItem(i.ToString()); //<-- arbitrarily using i as the value for the first column. You should use whatever makes sense to you.

 //TODO: add the sub item for the ID column
 item.SubItems.Add("");

 //Add in Watchers
 item.SubItems.Add(cwatchers[i]);

 //TODO: add the rest of the sub items

 //Add the item to the list view
 listView1.Items.Add(item);

You can safely get rid of the addwatchers method since it's only adding the corresponding subitem.

UPDATE

If you already have the items created when you call addWatchers, then the only thing you need to do is iterate through the items in the list view and add the missing sub items.

Let's say you have added in a previous process all the items to the listview. And when you did that, you created the listview item with two columns.

private void button2_Click(object sender, EventArgs e)

 string cwatchers = richTextBox2Text.Split('n');
 for (int i = 0; i < cwatchers.Length; i++)
 
 //Get the listview item in i and add the sub item for the watchers.
 //this assumes that the list view item is created and contains two subitems so the next one to be added is the wawtchers.

 listView1.Items[i].SubItems.Add(cwatchers[i]);

 //TODO: add the rest of the sub items
 

Hope this helps!
