combobox should support both multiple select AND LoadOnDEmand !

Hi , 

Why is your combobox does not support BOTH multiple select AND LoadOnDemand ?

It would be so convenient to have .

I see a lot of questions like that, but all the answers explain why its not supported.

I tried all other recommendations ( like using RadAutoCompleteBox or searchbox ) , but it's not displaying any items in the drop down list ,so the user has to know what he is looking for, withuy having ability to select it from the list. 

PLEase let me know if you have ANY Telerik control which allows both features .

If you do not have , I would like to submit a feature request for that .

I really do not care what control it will be .

All i need is to be able to select from the list ( with option to select all ) , OR to start typing , and then it will prompt for a matches .

Thanks ,

Hi Orit,

Load On Demand is not supported with CheckBoxes because the RadComboBox items loaded on demand are not accessible on the server and that is needed for the CheckBox feature.

This has been confirmed to be a Limitation of the Control and implementing it would require the ComboBox to be rebuilt with the new structure. That would result in a breaking change for all of those using it.

Instead, we have created a new control that would allow you to select multiple items. The Server Filtering and Virtualization functionalities would be the closest options that could overcome the ComboBox's LoadOnDemand+CheckBoxes limitation.
