Ajax Sample : Cultures Table

Setup for ajax

• Create a div element that will handle the updated the content
  <div class="items"></div>
• Create a partial view to render in the target area e.g. PagingItemsPartial.cshtml. The partial view model is the same as the page model in out sample PagingAjaxModel.
• Put the paging taghelper in the partial, currently it supports only "replace" mode for ajax, thats why we have to keep the paging inside the partial, so it will refresh with the partial data accordingly.
• Use ajax-... attributes to add ajax support to the PagingTagHelper.
• In the backend, create the relevant handler that will return the partial view via ajax.
• Add reference to ajax in the Scripts section:
  <script src="https://cdn.jsdelivr.net/npm/jquery-ajax-unobtrusive@3.2.6/dist/jquery.unobtrusive-ajax.min.js"></script>
