AssistanceBubble.js with ASP.NET UpdatePanel

Looking for guidance on implementing HelpBalloon.js () within an ASP.NET UpdatePanel. Experiencing issues with image loss after a postback.

Answer №1

Below is the solution that I have come up with:

Create a designated space for the image:

<div id="imageContainer"></div>

Then, insert the provided code snippet:

 <script type="text/javascript>
    var prm = Sys.WebForms.PageRequestManager.getInstance();
    prm.add_pageLoaded(Page_Loaded);

    function Page_Loaded(sender, args) {
      var helpBalloon = new HelpBalloon({ returnElement: true, title: 'Title', content: 'Text.' });
      $get('imageContainer').appendChild(helpBalloon.icon);
    }
</script>

Answer №2

This plugin is unfamiliar to me, but the concept behind it suggests that updating the JavaScript after the Panel loads is crucial.

Upon examining the code of the HeloBallon plugin, it appears to capture the onload event and execute the registerClassLinks function.

To ensure the function runs again when the panel is updated, you can implement this JavaScript code on your page.

var prm = Sys.WebForms.PageRequestManager.getInstance();    
prm.add_initializeRequest(InitializeRequest);
prm.add_endRequest(EndRequest);

function InitializeRequest(sender, args) {      
}

function EndRequest(sender, args) {
    HelpBalloon.registerClassLinks();
}

You will need to verify if this solution works or make any necessary adjustments, but this should give you a starting point.
