I have created a checkbox dynamically. It's local.

chkNew.CheckedChanged += new System.EventHandler(chk_CheckedChanged);


in my chk_CheckChanged function I want to find it's checkstate...

How can I reference this control since it is dynamic?

ie Controls("chk1").CheckState doesn't work

Thanks.

Use the sender parameter of your chk_CheckedChanged handler:
private void chk_CheckedChanged(object sender, System.EventArgs e) {
  CheckBox chk = (CheckBox)sender;
  if (chk.CheckState == CheckState.Checked) {
     ...
