Checkbox not evaluating to true even though it is checked

I have a gridview that has a register checkbox and a waitlist checkbox depending on some values I hide one of the checkboxes and display a star for some odd reason when I run my website one time it evaluates to true the next time i get some error saying 

Checked The name 'Checked' does not exist in the current context

.aspx

 <asp:TemplateField HeaderText="Register" ItemStyle-CssClass="template-center">
                        <ItemTemplate >
                            <asp:CheckBox ID="chkRegister" runat="server"/>
                            <asp:Label ID="lblStarRegister" runat="server" Text="*" ForeColor="Red"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Wait List" ItemStyle-CssClass="template-center">
                        <ItemTemplate>
                            <asp:CheckBox ID="chkWaitList" runat="server" />
                            <asp:Label ID="lblStarWaitList" runat="server" Text="*" ForeColor="Red"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>

code behind

  if ((((CheckBox)row.FindControl("chkRegister")).Checked == true) || (((CheckBox)row.FindControl("chkWaitList")).Checked == true))

Visible = false will not render your control. Use display:none to hide your control. It will be available.

Edit:

Use css like 

.hiddenelement
{
    display:none;
}

Apply this class on the checkbox you want to hide. like 

<asp:CheckBox ID="chkRegister" runat="server" CssClass="hiddenelement"/>

The checkbox will be hidden but available in code behind.

Edit2:

if (true)
{
    chkRegister.CssClass = "displaynone";
}
else
{
   chkRegister.CssClass = chkRegister.CssClass.Replace("displaynone", "");
}
