DataItems does not return the correct elements if virtualization is used (DPSN-13445)

Hello dear support,

I ve a strange behavior that I may qualify as bug.

I ve tried to reproduce here https://dojo.telerik.com/osEPIvOG wit a result shown in this animated gif here attached (DPSN-13445).

Basically what's happening is that if your are selecting / clearing elements that looked to be in different pages (view), the dataItems() function does not return the correct value, but some previous item.

This "bug" is always reproducible;

Please let me know if there is a bad implementation (I m using here basic Telerik sample) or if there is a workaround, or if I can expect a fix;

By advance thx for your swift reply.

Hi,

You are right - currently the items in the virtual scenario are not available on the client so if you need you get selected item by its value you should probably send a request to the server and return the desired item by its value.

I will increase the severity of the bug because of this inconvenience of the specific scenario.

Hello Plamen

Thank you for your reply.

Indeed we are using dataItems() instead of value() because this last only returns the id (key) of the object in the datasource and not the full objects in an array; And we need the full objects for complementary attributes.

Despite our searches I did not find a way to convert value to full item in the context of a virtualized combobox. It looks like the get(id) function the datasource only serves elements that are in the view/page.

May be I m wrong ?

Any hints on that subject would be appreciated.

Thanx for your reply again.

Hello,

It looks like a bug indeed.

I have converted the ticket to a bug report.

As a temporary workaround for it you can use the value method that is returning the correct id and then find the corresponding item as for example it is shown in this example - https://dojo.telerik.com/@zdravkov/EYaJiwIk.
