Winforms listview not showing items in detailsview?

This code works for me: using System; using System.Windows. Forms; public class LVTest : Form { public LVTest() { ListView lv = new ListView(); lv.Columns. Add("Header", 100); lv.Columns.

Add("Details", 100); lv. Dock = DockStyle. Fill; lv.Items.

Add(new ListViewItem(new string { "Alpha", "Some details" })); lv.Items. Add(new ListViewItem(new string { "Bravo", "More details" })); lv. View = View.

Details; Controls. Add(lv); } } public static class Program { STAThread public static void Main() { Application. Run(new LVTest()); } } Try this code for yourself in an empty project.

Then, focus on adapting it to your application: compare how your program is different from this code, and work on changing it to more closely match mine. It's OK if you lose functionality in your program; just try to get a basic version working. Then, add functionality back bit by bit so you can be sure that the program still works every step of the way.

If you're still stuck, post more code from your project and we might have a better idea of why you're having trouble.

Thank you, this pointed me in the right direction. What the problem was? I reloaded the listview every time with new data, and I did a lvw.Clear() to clear the list, but that also clears the columns, so no items are shown in details mode.It had to be lvw.Items.Clear().... – Michel Aug 23 at 10:56 Ooh, tricky.....! – James Johnston Aug 23 at 14:02.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
