Hi Saravanan,

Can you provide us some more details regarding what you're looking to do?

By default, a newly created tab will have no webparts inside. So if you add a wiki webpart, it will automatically bring up the screen you're seeing right now unless you have a default wiki page that will load instead (the webpart will identify the default wiki page due to the name of the page being called "default").

If there is no default, you would have to click that choose an existing page option if you wanted to use one of your existing pages to populate that webpart.

Are you asking if you could already have a pre-determined wiki page load (not necessarily the default) within that webpart once the tab is made?

Regards,

Jon
