actually my requirement is when i click on the button i want to display some message and when we press ok then it is redirect to another page is it possible

Change onClick to OnClientClick

You need to use the OnClientClick method, OnClick is the server side event. e.g.

<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return confirm('are you sure');" />

This code produces a message box which if cancelled, prevents the server-side event from being fired. If you click 'OK' to the message box the server event is fired as usual and you can then do your redirect as necessary.
