You will need to use JavaScript to toggle styles like you are trying

<asp:Button ID="btnFromCalOpen" runat="server" Text=""  OnClientClick ="ShowCal()" style="display:none;visiblity:hidden;" />

Original Comment You can’t do onLoad with JavaScript for any button. What are you hoping to accomplish? We can help figure out that solution.
