[Solved] Strainge behaviour for load on demand

[Yuriy Rogach]

Hi Guys,

I'm new with Prometheus, and here is what I need and what I get.

I need load on demand functionality, which will work like this:
If user click on arrow to open dropdown, then click on "Down" button on keyboard to go next record below and if this is the last record in current batch next batch is called from the server (call ItemsRequested?)

Now if you will go to the demo http://www.telerik.com/DEMOS/ASPNET/Prometheus/Combobox/Examples/PopulatingWithData/AutoCompleteSql/DefaultCS.aspx

And try to move down with keyboard, after the last visible record - you will get not next batch of record - you will get first record and note at the bottom "Items 1-1 out of 1" which is absolutely not correct.

And the same problem with regular radcontrols

Hi Yuriy Rogach,


I was able to reproduce the behavior you described. Generally, the virtual scrolling loads the items upon using the scroll of the drop-down area. It is not supposed to work when using the down arrow key.

We will research the matter to find out whether we can update the example to work the way you need. We will get back to you on the results.

I am seeing the same issue now with Q2 2009. Has any functionality been added to handle this?

Thanks!
