how do you call the function? What event is raised to call the function?

if the function is called when the box is changed; your code should work I guess. If you need to press a button to update the field i'd use this code:

C#

foreach (ListViewItem in listView1)
{
    ListViewItem find_name = listView1.FindItemWithText(textBox1.Text);
 
    if(find_name!=null)
    {
        //MessageBox.Show(find_name.ToString());
        //show_booked_details();
        find_name.BackColor = Color.DarkViolet;
    }
    else
    {
         MessageBox.Show("No Records Found");
         textBox1.Text = "";
         find_name.BackColor = Color.White;
         //show_booked_details();
    }

}

In your sample the search always begins at the first item, so it will only ever find the first occurrence. You need to use this version[^] of the FindItemWithText() method, to start the search at the item after the one that you previously found. You also need to optimise your loop so that it does not repeat for every item in the ListView.
