Hi,

I wonder if there is a way to turn checkbox on and off with only mouse click, not spacebar.

Could anyone tell me about it?

Thanks in advance!

You need to handle the keyup event and check spacebar key code in that to restrict.

Thank you, Tadit Dash! I solved it.

Why it is technically possible to block different input types and favor others, it is very unwise in most cases... By blocking input devices you block users with only that type of device (in most case these are people with disabilities)...

Already answered by Tadit Dash, but here is my code. Don't ask me why it also works with checked or unchecked state :)

C#

private bool checkBoxKeyFlag;

        // Prevent CheckBox to be set by keypress.
        private void checkBox1_KeyDown(object sender, KeyEventArgs e)
        {
            this.checkBoxKeyFlag = true;
            this.checkBox1.Checked = false;
        }

        private void checkBox1_CheckedChanged(object sender, EventArgs e)
        {
            if (this.checkBoxKeyFlag)
            {
                this.checkBox1.Checked = false;
                this.checkBoxKeyFlag = false;
            }
        }
