javascript - LinkButton on Master Page doesn't fire on Second Child Page in ASP.NET -

i'm creating project in asp.net (framework 4.0). have used asp linkbutton in master page & has 2 page linked (home.aspx & service.aspx).

question follows : linkbutton1 works on home.aspx , doesn't work on service.aspx.

user.master code follow

<ul class="nav navbar-nav navbar-right">     <li>         <asp:linkbutton id="linkbutton1" runat="server" onclick="linkbutton1_click" autopostback="true">signout               <i class="glyphicon glyphicon-off"></i>         </asp:linkbutton>     </li>     <li class="dropdown">         <a href="#" class="dropdown-toggle" data-toggle="dropdown">             <span>                 <asp:label id="lblname" runat="server" text=""></asp:label>             </span>             <i class="icon-user fa"></i>             <i class=" icon-down-open-big fa"></i>         </a>         <ul class="dropdown-menu user-menu">             <li class="active">                 <a href="frmuserhome.aspx">                     <i class="icon-home"></i> account                  </a>             </li>             <li >                 <a href="frmuserhome.aspx">                     <i class="icon-home"></i> personal home                  </a>             </li>             <li>                 <a href="#">                     <i class="icon-hourglass"></i> pending approval                  </a>             </li>         </ul>     </li> </ul> 

user.master.cs code linkbutton1 click

protected void linkbutton1_click(object sender, eventargs e)     {           if (request.cookies["asp.net_sessionid"] != null)          {              response.cookies["asp.net_sessionid"].value = string.empty;              response.cookies["asp.net_sessionid"].expires = datetime.now.addmonths(-20);          }          formsauthentication.signout();          session.abandon();          response.redirect("~/default.aspx");     } 

while inspect element (using chrome browser )on home.aspx page found below code

<li>     <a id="ctl00_linkbutton1" autopostback="true" href="javascript:__dopostback('ctl00$linkbutton1','')">signout           <i class="glyphicon glyphicon-off"></i>     </a> </li> 

and while on service.aspx (chrome browser inspect element)

<li>     <a id="ctl00_linkbutton1" autopostback="true" href='javascript:webform_dopostbackwithoptions(new webform_postbackoptions("ctl00$linkbutton1", "", true, "", "", false, true))'>signout           <i class="glyphicon glyphicon-off"></i>     </a> </li> 

why difference between home.aspx & service.aspx (while inspect element through chrome browser) ?

thanks original answer writer & @nimesh providing link .

set postbackurl property linkbutton server control, means cross page posting , asp.net framework instead of normal __dopostback() adds "webform_dopostbackwithoptions".

i'hv made changes according code requirement .

code linkbutton1 (user.master) page

    <li>     <asp:linkbutton id="linkbutton1" runat="server" onclick="linkbutton1_click"  postbackurl="~/default.aspx">signout          <i class="glyphicon glyphicon-off"></i>     </asp:linkbutton>     </li> 

if in case have not set "postbackurl", asp.net framework not add default button control, means there has control setting onclick attribute value using following sever side code .

code user.master.cs

protected void linkbutton1_click(object sender, eventargs e)     {           if (request.cookies["asp.net_sessionid"] != null)          {              response.cookies["asp.net_sessionid"].value = string.empty;              response.cookies["asp.net_sessionid"].expires = datetime.now.addmonths(-20);          }          formsauthentication.signout();          session.abandon();          postbackoptions mypostbackoptions = new postbackoptions(this);          mypostbackoptions.actionurl = "~/default.aspx";          mypostbackoptions.autopostback = false;          mypostbackoptions.requiresjavascriptprotocol = true;          mypostbackoptions.performvalidation = true;           // add client-side script hyperlink1 control.          linkbutton1.onclientclick = page.clientscript.getpostbackeventreference(mypostbackoptions);          response.redirect("~/default.aspx");     }
