using winform,
Which event do I use to make sure that as I am ticking items inside a checked listbox, a textbox is populated with those values?

I am using the selectedindexchanged but it does not work accurately.
For example, I put a tick next to two items, The textbox shows only the first item.
To also get the second ticked item in th etextbox, I have to click on another item in the checklistbox.

Any thoughts please?
Thanks

I'd try the ItemCheck event[^]. The name gives it away, don't you think.

Is it possible you are getting selected items and checked items mixed up? This works for me

C#

private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e) {
  CheckedListBox clb = (CheckedListBox)sender;
  if (e.NewValue == CheckState.Checked) {
    textBox1.AppendText(String.Format(Environment.NewLine + "Checking {0}", clb.Items[e.Index]));
  } else {
    textBox1.AppendText(String.Format(Environment.NewLine + "Unchecking {0}", clb.Items[e.Index]));
  }
}

Alan.

I tried this event but it still does NOT do what I am after.
i.e. if I tick two items, the second item only is shown in the textbox if I click on another item in the control.

I've added a code fragment.

Please try your code and see what I mean.
Note my previous explanation.
Thanks

I don't understand what you are trying to say and I would need to see how you are updating your text box before I could offer any further advice. If you are using the checked item collection bear in mind that the ItemCheck event fires before the check state of an item changes.

There is no OnClick event for this control.
