Client-side: synchronously wait for items to load

[Dili]

Hi everyone,

I'm manipulating a RadComboBox client-side in javascript using jquery and need some help. I'm loading items into the dropdown via the requestItems() method. I would like to do a synchronous wait until the dropdown has finished loading completely. I couldn't find any such methods in the documentation: http://www.telerik.com/help/aspnet-ajax/combobox-client-side-radcombobox.html

Here's my code

var cb = $find('RadComboBoxId');
var filterText = "my filter";

cb.clearItems();
cb.clearSelection();
cb.showDropDown();
cb.set_text(filterText);
cb.requestItems(filterText, false);
/* i would like to wait synchronously here until the list has completely loaded
   before proceeding to the next line. */
alert('all relevant items have been loaded!');

Does anyone know of a solution? Solution doesn't have involve jquery.

Thanks!

Hi,

In such scenario we recommend using the OnClientItemsRequested event which  occurs after the load-on-demand mechanism has added new items to the RadComboBox.

Hope this information will be helpful.

Hi Plamen,

Thank you for your reply! I was hoping to avoid using an asynchronous event but it seems there's no other pattern available from telerik to achieve this. I'll try something out in the next few days and post my solution here.

Thanks again!
