Select a row in listview

Question

I am web developer , working on a part of my project developed in WinForms. So my question could be a basic one. Try to bear with it.

I have two list views on my page and a remove button that works for both.

Problems.

1. I am not able to select a row in both the list view when I run my program, may be some property needed for it?
2. If I am able to select the row I want to detect which list view item has been selected, so how would I do that?

3. I have three columns and have bound the data by using the code below.

       listView1.Columns.Add("ID",20);
       listView1.Columns.Add("Name",40);
       listView1.Columns.Add("Mobile",40);
   
   
       foreach (var item in dataList)
       {
           newItem = new ListViewItem();
           newItem.SubItems.Add(item.ID.ToString());
           newItem.SubItems.Add(item.Name);
           newItem.SubItems.Add(item.Mobile.ToString());
           listView1.Items.Add(newItem);   
       }
   

but the ID column is left blank and the data starts to bind in these sense.

ID Name Mobile
   1    abc
   2    xyz

So how do I properly show the data?

4. Lastly I want to use my ID column to delete the data. So if I give width=0, is this the best way to hide a column?

Answer 1

1. See ListView.FullRowSelect property.
2. See ListView.SelectedItems property. Note, that by default ListView allows multiselection.
3. Set item text via constructor: newItem = new ListViewItem(item.ID.ToString());, then add rest of subitems (except of item.ID).
4. If you want to delete the column, just remove it from the columns collection.
