Load content

24 Oct 20182 minutes to read

By default, the content inside the content-template property element is considered as the content for the Dialog widget.

Also, we can render the Dialog widget content through the following ways.

  1. Request through AJAX

  2. Request iframe content

  3. Request image content

This settings can be specified through content-type property.

NOTE

Create a view page (AjaxContent.cshtml) which contains the content of the dialog.

  • CSHTML
    • <div class="control">
    <ej-dialog id="dialog" title="Dialog" content-type="ajax" content-url="@Url.Content("~/dialog/ajaxcontent").ToString()">
    </ej-dialog>
</div>

    AjaxContent.cshtml

  • CSHTML
    • <div id="content"> This content is loaded via AJAX request. </div>

    Load content

    We can handle the AJAX request’s success and failures through the events “ajax-success” and “ajax-error” events respectively.

    You can modify the previous example as below to handle the success and failure events.

  • RAZOR
    • <div class="control">
    <ej-dialog id="dialog" title="Dialog" content-type="ajax" ajax-success="onSucess" ajax-error="onerror" content-url="@Url.Content("~/dialog/ajaxcontent").ToString()">
    </ej-dialog>
</div>

    Add the below script to the view page

  • JS
    • <script>
        function onSuccess(args) {
            //handle success event
        }
        function onError(args) {
            //handle success event
        }
    </script>

    NOTE

    The same way we can render the iframe and image content for the Dialog widget by specifying the content-type as “iframe” and “image” respectively and also by specifying the proper location in the content-url property. If you wish to dynamically change the dialog content, you can set the content-url and the content-type property through setModel on any action.
