Question

I have a listbox in my winform, when an item in the listbox is selected, a value is placed into a textbox in the same Form. There my many items in my listbox which when selected, i want the text box to be empty so i can pass in the new value. How do i check is if the user has clicked on something other their initial selected item? i get the currently selected item like this below:

var selectedItem = (ReportItems)listbox.selectedItem

My solution was to always clear the textbox first. So as soon as a user selects an item in the listview, rather than populating the textbox straight away, clear the textbox before populating it.

clearText(); is called soon as a listbox item is clicked.

    public void clearText()
    {
        textBox1.Clear();
        textBox2.Clear();
        textBox3.Clear();
        textBox4.Clear();
        textBox5.Clear();
        textBox6.Clear();
        textBox7.Clear();
        textBox8.Clear();
        textBox9.Clear();
        textBox10.Clear();
        textBox11.Clear();
        textBox12.Clear();
    }
