If MultiSelect is set to true, you can use Selected property.
http://msdn.microsoft.com/en-us/library/system.windows.forms.listviewitem.selected.aspx[^]

C#

for (int i = 0; i < int.Parse(textBox1.Text); i++)
{
  checkedListView.Items[i].Selected = true;
}

Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead.

Take a look at the SelectedIndexCollection[^], it may help.

Solution 3

You should just set each items selected property to true. Something like this

C#

int amountToSelect = 0;
           int.TryParse(textBox1.Text,out amountToSelect);
           for (int i = 0; i <= amountToSelect; i++)
           {
               listView1.Items[i].Selected = true;
           }

Hope this helps
