CheckBox Control in Visual studio asp.net 2005 C#

May you please help me on this: I developed a web application that has Checkboxes and i want to show some controls when the user tick the box and hide them when the user untick the box. I only managed to do the showing part when the user tick the box, now i'm failing to hide them when the user untick the box.

Here is the showing part of the my code:

 protected void chkboxMentor_CheckedChanged(object sender, EventArgs e)
    {
        lblMentorName.Visible = true;
        txtMentorName.Visible = true;
        lblMentorStuff.Visible = true;
        txtMentorStaffNo.Visible = true;
        lblMentorDate.Visible = true;
        btnShowCal.Visible = true;
    }

Please help me with the hiding part.

You need to set the Visible property to the checkbox's Checked property.

        lblMentorName.Visible = chkBoxMentor.Checked;
        txtMentorName.Visible = chkBoxMentor.Checked;
        lblMentorStuff.Visible = chkBoxMentor.Checked;
        txtMentorStaffNo.Visible = chkBoxMentor.Checked;
        lblMentorDate.Visible = chkBoxMentor.Checked;
        btnShowCal.Visible = chkBoxMentor.Checked;

EDIT: More elegant solution would be to put these controls in a Panel and just set the Visible property of that using the checkbox's Checked property

As SLaks says

just set

<Yourontrolname>.Visible = chkboxMentor.checked

for each control you wish to toggle

protected void chkboxMentor_CheckedChanged(object sender, EventArgs e) 
{ 
     if(chkboxMentor.Checked)
    {
        lblMentorName.Visible = true;
        txtMentorName.Visible = true; 
        lblMentorStuff.Visible = true;
        txtMentorStaffNo.Visible = true;
        lblMentorDate.Visible = true;
        btnShowCal.Visible = true; 
    }
    else
    {

        lblMentorName.Visible = false;
        txtMentorName.Visible = false; 
        lblMentorStuff.Visible = false;
        txtMentorStaffNo.Visible = false;
        lblMentorDate.Visible = false;
        btnShowCal.Visible = false; 
    }
}
