Side Menu is hidden when opened main page at first time ASP.NET WebForms


Hello Support,
I attach new theme to my application. built with ASP.NET Webforms. the sidebar menu is hidden when open the page at first time.

see video please:


I test it in real host as you see in the video above.

Could you tell me if there's maybe javascript function to refresh menu at first time or something?

I use latest Metronic 8.2.8 version (Demo1)

my full <script>tag is :

<script>
 window.__bootstrap = { Tooltip: bootstrap.Tooltip };

 $(document).ready(function () {
 // do stuff here.
 $.fn.bootstrapBtn = $.fn.button.noConflict(); // fix conflict between jquery ui and Bootstrap

 // activate current opened menu-item
 // Get the current page"s pathname (path only, without the domain and protocol)
 var currentUrl = window.location.pathname;
 if (currentUrl == "/") {
 currentUrl = "/Default.aspx";
 }
 // Find the first .menu-link whose href matches the current URL
 var firstLinkWithHref = $(".app-sidebar-menu .menu-link").filter(function () {
 var linkUrl = $(this).attr("href");
 var linkListUrl = $(this).attr("data-href-list");

 if (linkListUrl == null || linkListUrl.trim() == "") {
 // Hide List Breadcrumb
 $("#linkList").parent().hide();
 }
 else {
 // Change href to data-href-list to allow visit list screen first.
 // KAMAL LATER
 }

 // If the link has a valid href and it matches the current URL, return true
 return linkUrl && (linkUrl === currentUrl || linkListUrl == currentUrl);
 }).first(); // Get the first matching link

 // If we found a matching link
 if (firstLinkWithHref.length > 0) {
 // Add the "active" class to the matched link
 firstLinkWithHref.addClass("active");

 // Traverse to the parent .menu-item
 var parentMenuItem = firstLinkWithHref.parents(".menu-item").first(); // skip first .menu-item as this (for <a>)
 var parentModuleSubMenuItem = parentMenuItem.parents(".menu-item").first();
 var parentModuleMenuItem = parentModuleSubMenuItem.parents(".menu-item").first();

 parentModuleSubMenuItem.addClass("here show");
 parentModuleMenuItem.addClass("here show");
 }

 var json = "<%=Newtonsoft.Json.JsonConvert.SerializeObject(ExaCloud.FExaAccounts.CurrentTheme)%>";
 const theme = JSON.parse(json);
 ApplyTheme(theme);

 // Keep Session Alive 
 setInterval(function () {
 fetch("/KeepSessionAlive.aspx")
 .then(response => console.log("Session refreshed!"))
 .catch(error => console.error("Error keeping session alive:", error));
 }, 19 * 60 * 1000); // Ping every 19 minutes

Hi,

Thank you for reaching out to us.

By default, when you switch direction, the sidebar must be open.

Please make sure that you have data-kt-app-sidebar-minimize="on" attribute added on your body element.

You can only set the default direction in thememode.json to change the direction dynamically, you should store user user-selected mode somewhere on your server, and then, if the value is set, use this value in KTBootstrapBase.InitThemeMode().

Hi, Lauris Stepanovs
I use conditional rendering mechanism that is exist in webforms.
in <head> tag i do this.


<!-- Fonts -->
 <% if (ExaCloud.FExaAccounts.UserLang == 2)
 { %>
 <link rel="stylesheet" href=" />
 <% }
 else
 { %>
 <link rel="stylesheet" href=" />
 <% } %>

 <!-- Plugin Styles -->
 <% if (ExaCloud.FExaAccounts.UserLang == 2)
 { %>
 <link rel="stylesheet" href="/assets/plugins/global/plugins.bundle.rtl.css" />
 <% }
 else
 { %>
 <link rel="stylesheet" href="/assets/plugins/global/plugins.bundle.css" />
 <% } %>

 <!-- Main Style -->
 <% if (ExaCloud.FExaAccounts.UserLang == 2)
 { %>
 <link rel="stylesheet" href="/assets/css/style.bundle.rtl.css" />
 <% }
 else
 { %>
 <link rel="stylesheet" href="/assets/css/style.bundle.css" />
 <% } %>



after that i don't find any flickers or any issues with sidebar.
and when user change language i just refresh a whole page. window.location.reload();

It works great now...
So now I don't think I need KTBootstrapBase.InitThemeMode() alright??

Hi,

Sorry for the late reply.

`KTBootstrapBase.InitThemeMode()` sets the default theme mode from Starterkit/_keenthemes/config/themesettings.json. If you don't want to use the configuration, you can just set the default mode directly in Starterkit/Views/Partials/ThemeMode/_Init.cshtml.

Please note I use RTL version and LTR version both.
When app start if UserLang is AR then call SetRtlMode method and change stylesheet with rtl.css versions.
