redirect on another page on button click
<p>I am creating a web app and I have 2 textboxes and one button with an input field</p>

<pre><code>&lt;input id="Login" type="submit" onclick="location.href='@Url.Action("loggedin","logincontroller")'" style="" width="200" height="34" value="submit" /&gt;
</code></pre>

<p>and my controller looks like</p>

<pre><code>public ActionResult loggedin(string role, string username, string password)
{
    webservice.loginservice a= new webservice.loginservice();
    a.getlogintype(role, username, password);
    return View();
}
</code></pre>

<p>with my webservice</p>

<pre><code>[WebMethod]
public string getlogintype(string role, string username, string password)
{
    string strtru="";
    string strfalse="";
    sqlcon;
    SqlCommand cmd = new SqlCommand("select * from [admin] where userid='" + username + "' and pass ='" + password + "'", con);
    con.Open();
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    DataTable dt = new DataTable();
    da.Fill(dt);
    if (dt.Rows.Count &gt; 0)
    {
        strtru = "true";

    }
    else
    {
        strfalse = "false";

    }
    con.Close();
}
</code></pre>

<p>My controller is calling the webservice and now I want to know how to redirect the page on successful validation. This is my first application using mvc I know there are many mistakes in this app(please let me know all the mistakes).</p>

<p>I am creating the application on mvc 5 and I am only using input fields not <code>@Html</code> syntax because I want to design it like(<a href="http://beta2.hti-india.com" rel="nofollow">beta2.hti-india.com</a>) this app is created by me on asp.net c#.</p>
