I click on items in the listBox user control right clicks and color the items <br/>
i click on in Red. I used a breakpoint on the New Form :
<pre class="lang-cs prettyprint prettyprinted
Code: 
<span class="kwd private<span class="pln  <span class="kwd void<span class="pln  listBox1_SelectedIndexChanged<span class="pun (<span class="kwd object<span class="pln  sender<span class="pun ,<span class="pln  <span class="typ System<span class="pun .<span class="typ EventArgs<span class="pln  e<span class="pun )<span class="pln 
        <span class="pun {<span class="pln 
            item <span class="pun =<span class="pln  listBoxControl1<span class="pun .<span class="typ MyListBox<span class="pun .<span class="typ SelectedItem<span class="pun .<span class="typ ToString<span class="pun ();<span class="pln 
            <span class="kwd this<span class="pun .<span class="pln f1<span class="pun .<span class="typ PlayLightnings<span class="pun ();<span class="pln 
            f1<span class="pun .<span class="pln pdftoolsmenu<span class="pun ();<span class="pln 
            <span class="typ int<span class="pln  indx <span class="pun =<span class="pln  listBoxControl1<span class="pun .<span class="typ MyListBox<span class="pun .<span class="typ SelectedIndex<span class="pun ;<span class="pln

            <span class="pun {<span class="pln 
                <span class="kwd if<span class="pln  <span class="pun (<span class="pln item <span class="pun !=<span class="pln  <span class="kwd null<span class="pln  <span class="pun &&<span class="pln  <span class="pun !<span class="pln pdf1<span class="pun .<span class="typ Lightnings<span class="pun .<span class="typ Contains<span class="pun (<span class="pln item<span class="pun .<span class="typ ToString<span class="pun ()))<span class="pln 
                <span class="pun {<span class="pln 
                    pdf1<span class="pun .<span class="typ Lightnings<span class="pun .<span class="typ Add<span class="pun (<span class="pln item<span class="pun .<span class="typ ToString<span class="pun ());<span class="pln 
                <span class="pun }<span class="pln 
            <span class="pun }<span class="pln 
        <span class="pun }
[/code]
And i see that Lightnings have items inside . But then when i click on the: <br/>
deleteSelectedLightningsToolStripMenuItem_Click in Form1 i see that Lightnings <br/>
is empty count 0. I cant figure out why.

I had the same problem with the variable counter in the listBox User Control wich was 0 also all the time. I cant find out why counter or Lightnings are getting reset or set to be empty . Tried to use breakpoints on all the places i did an instances for
the Lightnings list but when i click on the : deleteSelectedLightningsToolStripMenuItem_Click its never get to any of the instances. Same for counter variable in the listBox User Control used a breakpoint and it never get to the line in the listBox user control
code: counter = 0; so i cant understand where and why this variables get reset all the time. <hr class="sig danieli
