 return true;
else if(Ok!=true)
 return false;

Change your nick -- if you need to get something good, it's never "easy".
Was that you who vote "3" to all answers? Was that because those answers were not easy enough?

Adding to other answer, in order to talk to server from Javascript, there are few ways to interact:
1. XMLHttpRequest[^]
2. Callback[^]
3. WebService call[^]
4. PageMethod[^]

Pick one that suits you.

Have a look VB.NET/C# and JavaScript communication[^]. This pretty much explains a good approach.

Solution 2

can't you do this at your save button in aspx

<br />
<asp:Button OnClientClick='javascript:return confirm("Proceed to Save?");' id="Button1" runat="server" text="Save" onClick="Save" /><br />

will end up doing the same you want.
