    </div><!-- /content -->

    <div data-role="footer">
        <h4>
          @ All right reserved.
        </h4>
    </div><!-- /footer -->
</div><!-- /page -->

    </form>
</body>
</html>

Now on the server side

  protected void btnLogin_Click(object sender, EventArgs e)
{
    Response.Redirect("Home.aspx",true);

}
protected void btnCancel_Click(object sender, EventArgs e)
{
    UserName.Value = "";
    Password.Value = ""; 
}

but when I am clicking the login/cancel button nothing happen other than the Url is changed from

http://localhost:2278/Mobile/Default.aspx

http://localhost:2278/Mobile/Default.aspx#/Mobile/Default.aspx

What is wrong in my code? Can't I access Server side functions from ASP.NET server controls in JQuery Mobile? I am aware that it can be done better in MVC but that's not a option for me in this case.

Please help

This is because .net adds type="submit" to Button control by default. You need to set that to false and I would also set CausesValidation to false too, like this:

<asp:Button ID="btnLogin" runat="server" Text="Login"
OnClick="btnLogin_Click" CausesValidation="False" UseSubmitBehavior="False" />

in all fairness however, I wouldn't have used a server-side event just to navigate away on button click. You can achieve that with much easier way:

<a href="Home.aspx" data-role="button">Login</a>

..that's, of course, assuming you don't have to do any other server-side operations before navigating away.
