Ajax actionlink

Answer 1

Use an Update Panel. It will capture the post back from your delete link and asyncronously reload the content.

Take a look at http://www.asp.net/ajax/documentation/live/Tutorials/CreatingPageUpdatePanel.aspx for an example.

Hope that helps.

First, make sure that your delete link posts a form. Your question is not clear about this, but since you say that you are using a delete link I am guessing that you are doing this with a GET. Actions that modify resources should be done via POST, not GET.

Once you've done that, you can use the jQuery AJAX form plug-in to do the post via AJAX. It's quite simple, and once you have a working form to do that delete, you will find converting its to use the AJAX plug-in to submit the form instead very straightforward. Just follow the examples on the site.

Use jQuery:

<script type="text/javascript">
    function deleteComment(id) {
        $.post(
            "/MyController/DeleteAction",
            { id : id }
            function (data) {
                // do some gui updates
            });
     }
</script>

And use in a link:

<a onclick="deleteComment(<%= CommentId %>); return false;" href="#">Delete</a>
