.NET Listview Refresh

Question

I have the following code, which basically takes values from a database and populates a listview.

using (IDataReader reader = cmd.ExecuteReader())
{                  


        

Answer 1

Like this:

try
{
    lvwMyList.BeginUpdate();
    //bla bla bla

}
finally
{
    lvwMyList.EndUpdate();
}

Make sure that you invoke lvwMyList.Items.Clear() after BeginUpdate if you want to clear the list before filling it.
