示例1: listView1_SearchForVirtualItem
//This event handler enables search functionality, and is called
//for every search request when in Virtual mode.
void listView1_SearchForVirtualItem(object sender, SearchForVirtualItemEventArgs e)
{
//We've gotten a search request.
//In this example, finding the item is easy since it's
//just the square of its index. We'll take the square root
//and round.
double x = 0;
if (Double.TryParse(e.Text, out x)) //check if this is a valid search
{
x = Math.Sqrt(x);
x = Math.Round(x);
e.Index = (int)x;
}
//If e.Index is not set, the search returns null.
//Note that this only handles simple searches over the entire
//list, ignoring any other settings. Handling Direction, StartIndex,
//and the other properties of SearchForVirtualItemEventArgs is up
//to this handler.
