CheckedListBox disabled, how to scroll?

[=?Utf-8?B?VmljdG9y?=]

Hi,

A simple, but yet frustrating issue. I am using CheckedListBox control on a
Windows Form in a C# application. When I disable CheckedListBox, the vertical
toolbar is becoming disabled also. So the user has no way to scroll control
up and down to see what items are checked and what are not.

Is it a way to disable control (so the user wouldn’t be able change checked
items), but leave the control scrollable?

Can be done by overriding WndProc and canceling some messages there?

Thanks,
Victor

You probably could use WndProc, but here's a quick hack that does it
more simply:

private void checkedListBox1 _ItemCheck(obje ct sender, ItemCheckEventA rgs
e)
{
e.NewValue = e.CurrentValue;
}

Eq.

I found a solution. Overriding OnItemCheck works nicely.
Thanks.

bool disableCheckBox es = true;

protected override void OnItemCheck(Ite mCheckEventArgs ice)
{
if (disableCheckBo xes)
ice.NewValue = ice.CurrentValu e;

base.OnItemChec k(ice);
}
