What is the difference between OnClick and OnServerClick in web button control

1. What is the difference between OnClick and
OnServerClick in web button control

If I have a asp button control as follows

<asp:button id="SubmitOrder" Text="Submit Order"
OnClick="OnSubmit_Click()" runat="server" >
</asp:button
If the above is going to fire server side function what is
the difference between
OnClick and OnServerClick

2. I have function OnVerifySubmit_Click() which I would
like to run before
posting page to server

What is the correct way

<asp:button id="SubmitOrder" Text="Submit Order"
OnClick="OnVerifySubmit_Click()" runat="server" >
</asp:button
or

In the page.load SubmitOrder.Attrubutes.Add
("onclick", "OnVerifySubmit_Click()")

Appreciate your help

Thanks
KrishnaOnclick runs client side generated code, onserverclick runs server side
code. These hooks are provided for controls that derive from htmlcontainer
base controls.

Either will do. It's a matter of style really.

Regards
