checkedit group, making it possible to have no boxes checked

I am working with CheckEdit controls that have the same radiogroupindex, however I want to have the ability to let the user have ALL boxes in the same group unchecked. Is this possible with CheckEdit?

For example, I have a Yes and a No checkbox in the same group, but I want to be able to have both unchecked and have everything still work.

thanks

Hi,
To achieve your goal, handle the CheckEdit.CheckedChanged event in the following manner:

C#
void checkEdit1_CheckedChanged(object sender, EventArgs e) {  
    if (Control.ModifierKeys == Keys.Control) {  
        checkEdit1.Checked = false;  
        checkEdit2.Checked = false;  
    }  
}

This code allows you to set the Checked state to false if the Control key was pressed when clicking the CheckEdit.
I have created an example to demonstrate this. Please try it on your side and inform me of your results.

This works, however, it allows both Yes and No to be checked at the same time, which is not what I want. I need it to have three states basically, yes checked, no checked, or neither checked.
thanks

Nevermind, it works like you said. However, is there anyway to do this without using the control key?

Hi Matthew,
You can set the Checked state of the CheckEdit control via the right mouse button click. For this handle the CheckEdit.MouseUp event in the following manner:

C#
void checkEdit1_MouseUp(object sender, MouseEventArgs e) {  
           if (e.Button == System.Windows.Forms.MouseButtons.Right) {  
               checkEdit1.Checked = false;  
               checkEdit2.Checked = false;  
           }  
       }

I hope you find this information useful.
