Hi CJL,

I performed a test based on your description but I didn't reproduce the
problem.

I set up a Windows application project and drag&drop a ListView from
Toolbox onto the form. I set the VirtualMode property of the listview to
true and the VirtualListSize property to 10 and handle the
RetrieveVirtualItem event of the listview.  I add a button on the form to
show the selected indices. The following is the code in the form.

public partial class Form1 : Form
   {
       public Form1()
       {
           InitializeComponent();
           this.listView1.RetrieveVirtualItem += new
RetrieveVirtualItemEventHandler(listView1_RetrieveVirtualItem);
       }

       void listView1_RetrieveVirtualItem(object sender,
RetrieveVirtualItemEventArgs e)
       {          
           ListViewItem item = new ListViewItem(e.ItemIndex.ToString());  
       
           e.Item = item;              
       }

       private void button1_Click(object sender, EventArgs e)
       {
           MessageBox.Show("SelectedIndices: " +
this.listView1.SelectedIndices.Count.ToString());
           for (int i = 0; i < this.listView1.SelectedIndices.Count; i++)
           {
               
MessageBox.Show(this.listView1.SelectedIndices[i].ToString());
           }          
       }
 }

Build the project and run it. If I select 3 items using Shift key in the
listview and click the button on the form, a message box pops up saying
'SelectedIndices: 3' firstly and three message boxes show up consequently
and each of them says the index of each selected item.

Is there any difference between your project and mine? If yes, you may show
me some sample code or send me your project that could just reproduce the
problem. To get my actual email address, remove the 'online' from my
displayed email address.

I look forward to your reply.

Sincerely,
Linda Liu
