Question

I just stumbled upon the SetItemChecked and SetItemCheckState when working on a checked listbox.

The SetItemChecked takes an listindex and True/false to either set the listitem to checked or unchecked.

The SetItemCheckState takes an listindex and a CheckState-enum to set the state to either checked, unchecked or Indeterminate.

Why does SetItemChecked exists, when SetItemCheckState does cover all states?

Is it just to make it easy to use a boolean because its the most common use to check/uncheck or has I missed something?

And if it just to make it easier to use a boolean, why not have that as an overload to the function?

Thanks.

There is no real difference. SetItemCheck calls SetItemCheckedState like so:

public void SetItemChecked(int index, bool value) {     this.SetItemCheckState(index, value ? CheckState.Checked : CheckState.Unchecked); } 

Like you’ve already assumed, I guess it’s just a helper-method to make things simpler for the developer.
