Instead of having the property to select single or multiple it would be more productive to have a property called SelectCount and we can enter the amount of listings to be selected. If its a single I select 1... for multiple I select how many I need. No more need for the Single/Multiple property except for backward compatibility.
Hello David,
The RadMultiSelect, a server wrapper of the Kendo UI MultiSelect widget, has the functionality to limit the number of selected items.
The RadMultiSelect is included as of R1 2020, which you can check in our online demos and download from "your account" page:
