This method simply refers the request to the underlying list's Find method.

The following code example demonstrates how to use the Find method. For the complete example see the class overview topic.

private void button1_Click(object sender, EventArgs e)
{
    if (binding1.SupportsSearching != true)
        MessageBox.Show("Cannot search the list.");
    else
    {
        int foundIndex = binding1.Find("Name", textBox1.Text);
        if (foundIndex > -1)
            listBox1.SelectedIndex = foundIndex;
        else
            MessageBox.Show("Font was not found.");
    }
}
