DISREGARD: Resolved. :)

First, a checkbox is a LAST RESORT. I am trying to emulate the foxpro toggling of values in .net

Ok, I have a textbox control that is used for a bit field in SQL Server (1 or 0) TRUE or FALSE. By default, the value is TRUE or FALSE. I want it to toggle between Y and N. I have that working using the keypress event. I am also changing the value in the _TextChanged() so that when data is first loaded, it displays Y instead of TRUE and N instead of FALSE. Both of those work fine.

Now, my problem is in saving the value. Obviously it raises an exception. How do I save TRUE instead of Y and FALSE instead of N? Where is the best place to put that code? For this form, values are saved when the control is exited, not using a save button.

Also, is the way I have done it so far ok? Is there a better way? Should the code below be some place else? I'm am not comfortable yet with which event runs when and where I would put code...

        private void txbisactive_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == (char)32) 
            {
                if (((TextBox)sender).Text == "TRUE")
                {
                    ((TextBox)sender).Text = "N";
                }
                else
                {
                    if (((TextBox)sender).Text == "FALSE")
                    {
                        ((TextBox)sender).Text = "Y";
                    }
