    if(condition is okey)
    { 
        // go default.aspx
    }

Sounds like you just want to do a redirect:

protected void BtnLogin_Click(object sender, EventArgs e)
{
    if(myCondition)
    { 
        Response.Redirect("/default.aspx");
    } 
    else
    { 
        //stay this page
    }
}

If you want to retain the POST data, you can use Server.Transfer instead (note: based on your edits, it doesn't sound like this is what you need - I think you just need Response.Redirect):

Server.Transfer("/default.aspx");

Note that transferring the handler of the POST like this will not cause a browser redirect and therefore will not change the browser URL.

If you need to actually POST to a different URL and have the browser update, you'll need to post directly to that URL using a cross-page postback (using the action attribute on the form element), validate on that page and then redirect back to the original page if validation fails.
