Checkboxlist index issue

Question

Hello there. i want to make an application, i use a checkboxlist, and i want to retain in an array checked or unchecked indexes like this: for unchecked items, the array location should be a 0, and for checked items, the array location should be 1.

i tried like this:

[code]

private void checkboxlist1_SelectedIndexChanged(object sender, EventArgs e)

{

     int[] v=new int[6];

     for(int i=0;i<6;i++)

if(checkboxlist1.getitemchecked(i))

v[i]=1;

else

v[i]=0;

  string w=v.ToString();

}

[/code]

and then , the result is wrong. for example, if i check the first three items, the result will be 110000. it seems it's a step behind or something. should i use itemcheck event instead of selectedindexchanged, or both, or what? thank you
