Javascript Intellisense

[Christopher Blickley]

What is the best way to get Javascript Intelliense working on the controls within an client-side event when an item is passed into the event instead of the entire RadControl?  For example, in the RadMenu's OnClientItemClicking event, the second parameter passed in has a "get_item" functioin that grabs the RadMenuItem that was clicked. Is there a way to get Intellisense working on that item?  An example would in the following snippet from the docs, where I would love to get Intellisense on the "item" variable.

Thanks,
Chris

<script type="text/javascript">
function onClicking(sender, eventArgs)
{
  var item = eventArgs.get_item();
  var navigateUrl = item.get_navigateUrl();
  if (navigateUrl && navigateUrl != "#")
  {
    var proceed = confirm("Navigate to "+ navigateUrl + " ?");
    if (!proceed)
    {
      eventArgs.set_cancel(true);
    }
    else
    {
      eventArgs.set_cancel(false);
    }
  }
}
</script>

Hello Christopher Blickley,

At this moment it is a limitation because there is no easy way to say to handler what item it contains.

Sorry for the inconvenience.

Thanks Veronica,

Maybe a future enhancement could be to provide functions for the items like are currently being provided for the main control, like "toMenuItem()".  I worked around it be calling "toMenu" on the first parameter, then called "findItemByValue" on the RadMenu object, passing in eventArgs.get_item();  This seems to work, but requires those extra steps.  I suspect that many people would benefit from Intellisense on the "item" objects passed in to the client-side handlers since, at least in my case, this is the most frequent place I work with the RadControls on the client.

Thanks,
Chris

Hi Christopher Blickley,

Thank you for the suggestion. We'll make sure to make this improvement in future versions as it will be useful indeed.

Meanwhile, you can create your own 'toMenuItem' method:

function toMenuItem(object) {
    /// <summary>Casts an object to a RadMenuItem instance</summary>
    /// <returns type="Telerik.Web.UI.RadMenuItem">A RadMenuItem instance</returns>
    return object;
};

It simply returns the passed object which is enough to give Visual Studio a 'hint' about the returned type.

Kind regards,
