I have a RadGrid with radio buttons on the inside of a FormTemplate. I want hide the panels below or show the panels below on checkchanged of the radio button.

However, my issue is that i don't know how to access the panels oncheckchanged. Any help would be appreciate. Thanks in advance.

   protected void RadioButtonCompany_CheckChanged(object sender, EventArgs e)
{
    RadioButton RadioButtonCompany = (RadioButton)sender;

    Panel pnlPerson = (Panel)RadGridInjuries.Items[1].FindControl("pnlPerson");
    Panel pnlcomp = (Panel)RadGridInjuries.MasterTableView.FindControl("pnlComp");

    if (RadioButtonCompany.Checked)
    {
        pnlPerson.Visible = false;
        pnlcomp.Visible = true;
    }
    else
    {
        pnlPerson.Visible = true;
        pnlcomp.Visible = false;
    }

}
