How to clear data from list view in c#

Question

I have a button \"Show data\". When click it, data will display in list view. But I want to clear it and then click \"Show data\" again to display new data. Because I don\'t

Answer 1

listView1.Items.Clear();

Clears in 2008 c# column headers with the data, if you have multiple ListView on the same form the best way is writing a method such as (suggested by Lasse as above)

private void ClearLvItems(ListView li)
{
   while(li.Items.Count>1)
      li.Items.RemoveAt(1); 
}

Or if it does not work as expected as it does not work with me (one row still rests in Listview)

 listView1.Items.Clear();
 SetHeaders(li); // If you have more then one ListView in the same form. Otherwise don't use the parameters.

 private void SetHeader(ListView li)
 {
   string[] header_names = new string[] {"Id","Name","SurName","Birth Date"};
    int i = 0;
    foreach (ColumnHeader ch in li.Columns) 
    {
        ch.Text = header_names[i];
        ++i;
    }
 }
